Xserve RAID - ADM

Can I install an Apple Drive Module 1TB SATA in a Xserve RAID (M9721LL/A)? If not, what the maximum capacity of this RAID model? Thanks!

The Xserve RAID take ATA drives not SATA drives and the maximum capacity (with firmware 1.5.1) is 750MB so "No".

  • Expanding xServe RAID Array - updated info sought.

    I don't want to have to reformat the RAID and I don't want to lose data because...
    1) The organization will suffer extended downtime.
    2) I don't have ready access to 3TB of empty storage to back up the entire contents of the RAID.
    These and Apple's documentation are a few of the many different sources of info on this topic I've sought.
    With apologies in advance to William Lloyd, who has answered many of these questions.

    My (familiar) situation.
    I inherited administration responsibilities for an xServe RAID using the latest firmware (1.5.1).
    The xServe is an intel xeon dual 2 GHz, running Mac OS X Server 10.6.8
    The RAID had six (sigh) drives in the left controller. None in the right.
    When I became admin, one of these six was dead. So I went on eBay and got three refurb ADM's.
    --one to replace the dead drive.
    --another to expand the RAID 5 to a full seven drives. (from 2.5T to 2.73T)
    --a third to put on the shelf as a spare.
    Now then.
    The replacement drive rebuilt beautifully. Happy 6 drive RAID.
    I put in the 7th drive and expanded. It took several days.
    I'm at the point of "merging" slices that gives everyone pause about losing data.
    Much discussion here about whether this can result in added capacity without destroying data relates to earlier versions of Mac OS X Server and G5 not Intel xServes. So that's a point that I think I could use some clarity on. Can Intel Macs can expand the file system with this slice-merging function without data loss whereas Power PC Macs cannot?
    Next, my RAID as I inherited it was one slice. That is to say, one volume. One partition. In RAID Admin under "Arrays and Drives" all the little drives display a [1]. They did when the RAID was degraded to 5 drives. They did when I added the 6th drive replacement. They do now, having used the Expansion function under "Advanced" to add the 7th drive.
    So, next question. WAS IT EVER SLICED?
    That seems to be a deal-breaker for merging slices without data loss.
    For this, I looked in RAID Admin to my Events tab which dates all the way back to 2008.
    I see exactly zero mentions of slicing anywhere. Come with me on a journey, won't you?
    You'll see my expansion and verification up top.
    The drive failure in October 2013.
    Other exciting things. But no slicing.

  • Adding Additional Drives to 3.55 Xserve RAID

    So, we just purchased the 3.55 Xserve RAID (7 500gb ADM's). I'm surprised to read that I cannot "grow" the volume by adding ADM's without reformating the volume using OS X. Is this still true?
    Our intention was to simply add ADM's as needed, however this is likely not going to work... if each time I need to offload the data and reformat the volume.
    Annoyed.

    Xsan allows you to aggregate fibre channel LUNs (analogous to "disks") into what are called "storage pools." You then aggregate storage pools into volumes. So to grow a volume, you can either add more LUNs to an existing storage pool, or you can add more storage pools to a volume.
    A bit technical.
    Keep in mind that to run Xsan, you will need a few things:
    1) A fibre channel card for every machine that wants to access the volume over fibre
    2) A dedicated ethernet network which is separate, and used specifically for metadata traffic on the volume -- this enables Xsan to do file locking
    3) A pair of dedicated metadata controller machines -- preferably Xserves with > 2 GB of RAM, to manage the SAN.
    At minimum, figure $20K on top of the storage to get started with Xsan, if you want it to perform well and be reliable. You owe it to yourself to get Xsan training and certified as well -- making errors early in the planning/deployment process can magnify later on.
    Xsan is great for what it does best -- high speed, shared, video editing -- but to just give the ability to grow a volume, I personally think it's overkill. If you can stick to one RAID you could probably do a concatenated RAID volume with OS X's built-in RAID.

  • Expanding a XServe RAID and Striping

    Greetings!
    I have an XServe RAID with four 250 GB ADMs inside the 1-4 slots of the Upper or left controller. This one array totals 701.27 GB at RAID 5 showing up on my Desktop as one RAID.
    I recently acquired two ADMs, a 750 GB and 500 GB, and I'd like to install them in my vacant second controller on the right, slots 8-9. I'm pretty sure I can create another array with these two drives setting them at RAID 5. Then what I'd like to do is stripe the two arrays, using Disk Utility, and create a software RAID that will show up on my desktop as one RAID. (I currently use this RAID as my Final Cut Pro media drive.)
    My questions are: Am I on the right path?
    If I stripe them together, I will lose my data on my existing array, correct? (I have the data backed up on another external drive so when I'm done I can copy it back)
    I feel is best to have one RAID rather than several. Or should I consider having two RAIDs but being cognizant that I will have to stay on top of of my Final Cut Capture Scratch media folders as I edit? (ie, Two RAIDS = two separate Capture Scratch folders. So I'd have to choose what Final Cut media will be on what RAID, etc. rather than one folder where all the media can go)
    My goal down the road is to completely populate the left/top controller with 250 GB ADMs. If I do, I would assume I can expand the side with the 250's by merely using the Expansion function? Would this "upset" the prospect of having a single RAID of two striped arrays?
    Thanks in advance!

    William Lloyd wrote:
    This doesn't sound like a good idea. You're mixing stuff in a variety of configurations that don't match, and if you want to stripe the two sides, they should match for optimal performance.
    As in: they should all be 250 GB ADMs, right?
    With the 750 GB and 500 GB drives, your options are RAID 0 (with NO protection) giving ~ 1 TB of storage, or RAID 1 (mirror) giving ~450 GB of storage. The latter is probably preferable.
    So I could install them into the right side controller and make an array of the two using RAID 1 (mirror) and end up with 450 GB of storage. I'll get the protection but losing the extra storage because it would defer to the smaller size 500 GB ADM. And I can't add them to the other side where the 250 GB ADMs are because you're not supposed to mix different size ADMs on the same controller. (This is the stuff that is not in Apple's fine print when they sell it to you. You find it out either through Discussion threads or Technical Articles.)
    If you were to attempt to stripe this with the other side, you'd have either 1.4 TB or 900 GB of storage, respectively. In the former case, if one of the drives on the right side failed, you would lose 100% of your data on the entire volume.
    My option(s) would be: install the two non-compatible sized drives into the right side controller, combine them as a RAID 1 array and then have two separate RAIDs on my desktop, with the second RAID being physically larger than the other but actually smaller because of the incompatible 750 and 500 GB sizes. Then, when editing with Final Cut, I'd have to choose which RAID that I wanted to store my media on.
    So if I were you, I'd give up trying to make it look like one volume.
    Agreed. But are there any other options I can explore? I purchased the 750 and 500 GB drives naively thinking I could expand the storage of my Xserve RAID by buying larger drives. Now I'm finding out I should have purchased only 250 GB ADMs-- but they weren't available from Apple when I was able to purchase additional drives and no one told me otherwise. Until now.
    Thanks for your learned reply. I guess I should have consulted with you/Xserve RAID Discussions before buying anything.

  • Xserve RAID: Server Monitor says degraded, disk utility says mirror FAILED.

    Xserve Quad Intel 4x2GH
    4096 GB RAM
    OS X Server 10.4.11
    Xserve RAID 7TB 14x 500 GB ADM via dual fiber channel, Mirrored, 3.5 TB array.
    Flashing yellow indicator light on Xserve this morning. Investigated and found that RAID Admin says everything is OK, all 14 drives normal.
    RAID Admin log says :"4000 1 Wed Apr 08 09:37:59 EDT 2009 Disk 2 Failed To Respond. Retrying. RETRY COUNT:0 LBA:0x1C700"
    Under the RAID tab, Disk utility says: "Mirrored RAID Set: Degraded" and "Disc2s3: FAILED"
    All LED's are solid green across the front of the ADMs.
    Since all my drives are reporting OK, could this be a problem with the Fiber Channel interfaces?
    Should I just backup (again), shut down and rebuild the mirror using Disk Utility?

    Hi Kappy<
    I am trying to migrate user data from a RAID - 1 slice from my old PowerMac G4 running OS X 10.4.11 to my new MacBook Pro running OS X 10.5.4 by reading a mirror RAID slice from my old Mac that is mounted in an external drive enclosure and connected by FireWire.
    The problem is that the new Mac cannot read the old Mac disk, it never shows up on the desktop, or comes up as available when trying to use Migration Assistant. Then, if I go into Disk Utility, the external RAID slice shows up briefly with a locked yellow padlock beside it, then I suddenly get the window shade of death, and have to hold down the power button to reset/restart my MacBook.
    Why can my new computer not read my old computers disk, and how can I change permissions, or make the old drive readable by the new mac.
    Regrettably I am away from the original Desktop, and cannot load the old drive back into it, connect the two machines and migrate that way. My only option for reaching my necessary data is to retrieve it off the drive I have with me.
    Thanks in advance for any help you can offer.

  • Xserve RAID won't mount on G5.

    Hi,
    We purchased an an Xserve RAID yesterday that has 4 x 500Gb ADM's in it. I was checking out the different options in RAID admin and the Xserve was working perfectly, the unit was mounted on the desktop. I changed the RAID type from something I was experimenting with back to RAID 5. This was fine, after erasing the RAID, it showed on the desktop. I copied around 250Gb of data to the Xserve, and it was going fine, until the last Gb or so failed because the name of a file was too long. I thought this was odd, as both the source and destination devices were jHFS+. The RAID then stopped responding, and this required me to forcibly restart the G5. Upon doing this, the RAID didn't show on the desktop. I went into Disk Utility, and there was nothing.
    I restarted both the G5 and Xserve multiple times, reseated the fiber card, fiber connections, drives, control modules and reset the control modules. This still didn't work. I deleted the RAID array and created another, the RAID was still invisible in Disk Utility. System Profiler reports that a fiber connection is established. I can't remember the LUNs it shows though.
    Does anyone have any ideas?
    Any help is much appreciated.
    Thanks!
    Elijah

    I have managed to fix the problem (at least it's still going at the moment...). We were just about to return the Fiber Card to Apple, but just before I removed the card from the G5 I had one last look at the settings on the RAID. Previously I had noticed that LUN Masking was on. I didn't take much notice of this before, as I read in an Apple manual somewhere that LUN Masking is always on while the Xserve is initializing the disks. As a last resort I thought to try and force LUN Masking to be disabled. I changed the array to JBOD, so the disks wouldn't be initialized, and entered the advanced settings. I then went to the LUN Masking section and turned off masking for both controllers. I then shut down the Xserve and unplugged it for 10 minutes.
    I then turned on the Xserve and the G5 and to my utter delight, the G5 said "Unrecognized disk inserted"! The G5 was finally seeing the RAID.
    I then formatted the RAID and everything has been fine since (4-5 hours).
    I have no idea how LUN Masking turned on, the masking list had no devices in it, so the RAID was basically disallowing anyone access through fiber. Upon turning masking off, the RAID reappeared on the G5. Apple support said nothing about LUN Masking when I on the phone to them. I guess they though resetting the RAID controllers would reset the LUN Masking, but it doesn't seem to. I repeat: Resetting the RAID controllers does not reset LUN Masking.
    All along this was the problem, but no-one at Apple or the reseller we purchased the Xserve RAID from thought of it!
    I hope this helps someone out there.

  • XSERVE RAID Disk Failed to Recover After Reset...

    Greetings,
    I've got an PATA XSERVE RAID with 14x250GB Dries setup as RAID 5.
    Last week event monitor reported that Disk 14 Reported An Error Command 0x35 ERROR 0x10 STATUS 0x51 LBA 0X3978B80.
    Not having a spare Drive available, I ordered one and Reconditioned the Raid Using the RAID Admin Tool. 3 days later it reported all as well. This morning my new ADM arrived and before I could replace Drive 14, it started generating basically the same Error.
    So I swapped in the New Drive, and it began to rebuild, now here's the kicker...
    After a few minutes it started giving me this ERROR:
    DISK 14 FAILED TO RECOVER AFTER RESET. RETRYING
    then...
    DATA WAS LOST DURING A REBUILD.
    It continued to repeat these messages until it Finally reported:
    DISK 14 OFFLINE
    So, I thought it must be a bad Drive, So I figured let me kill 2 birds with 1 stone and swap out a drive I had working fine in an XSERVE. So I ejected the new drive from the XSERVE RAID and Replaced it directly with the Drive from the XSERVE (Also 250GB) And...
    It did the Same exact thing, same errors, etc.
    So what's going on?
    RAID ADMIN reports all Components OK
    Any help is appreciated.
    Thanks
    LJS

    OK, So replying to my own issues here...
    So I've replaced the Lower Controller and updated the firmware on that Controller.
    The I ejected disk 14, waited a minute or 2, then re-inserted the Disk, then made it available for use.
    It attempted to add to the existing RAID and the errors started all over again (See 1st post)
    So apparently it wasn't the controller.
    So I figured it must be the RAID Set itself, so to be sure, I swapped Drive 8 with Drive 14.
    Deleted the ARRAY and Re-Created it, it's building now and Now Drive 8 is offline, So it would appear to be the drive, but I already replaced it with a known working drive, a new one from Apple, and then one directly from my XServe (See 1st post)
    So I'm just baffled at this point.

  • Mac Pro + XServer RAID + FCP2 + Configuration

    Hello all. This is my first post here.
    I will soon buy a MacPro por video editing on Final Cut Pro 2 and I was wondering if you could help sort out if the configuration I've chosen is the best.
    I'll show you the configurations I thought first:
    *Mac Pro*
    - Two 3.0GHz Quad-Core Intel Xeon
    - 4GB (4 x 1GB)
    - Mac Pro RAID Card
    - 2 x 500gb HDD
    - ATI Radeon X1900 XT
    - 20" Apple Cinema Display + 23" Apple Cinema HD Display
    - Dual-channel 4Gb Fibre Channel PCIe
    *XServer RAID*
    - 2000GB ADM (4x500GB Ultra ATA)
    - Cache Battery Back-up Modules
    - Dual-channel 4Gb Fibre Channel PCIe
    My idea:
    A) The MAC Pro I'll be used for 3D rendering and video editing. I'll configure the 2x500GB with RAID1 (mirroring) for a fail safe env, leaving my with 500GB of available space
    B) XServer RAID will be connected directly to the Mac Pro (for now) via the fiber optic cards and we'll provided additional storage.
    C) For projects stored on the XServer RAID (videos for example) I must be able to access and edit directly with FCP2 without having to pass it to the Mac Pro
    D) I was thinking of using RAID5 for XServer RAID configuration leaving me with 2.64 x 500GB (as described on support faqs) = 1.3 TB of disk space with a reasonable fail safe environment (RAID5 with 3 drives allows one drive to fail and offers a good recovery rate).
    OK. My questions:
    1) Is my MacPro config enough for FCP2 + 3D Rendering ?
    2) Can I use the XServer RAID directly with Mac Pro or do I need aditional software / hardware?
    3) Can I connect the fiber optic from one board to the other without using the router? (on google the answers I found were very vague...)
    4) Is the RAID5 the best choice (in terms of performance vs data recovery) for video editing. The RAID5 specs states that random writes to disk are slower that other RAID configs. Is RAID 50 (5+0) a better choice?
    5) I opted for the 4 HDD config on XServer but I could change to a 7 HDD config for a similar total space.
    I'm sorry for the long post, but I can't find anywhere suitable information about this questions.
    Hope to hear from you.
    Thanks in advance!

    We have a ton of Xserve's and Xserve RAID's at my work. As of right now they're all directly connected to our servers with Fibre Channel cables (NOT fiber optic, totally different animal.) We finally just bought our first Fibre Channel switch to hookup five 10.5TB RAIDS and a huge tape loader for backups. The RAID's work perfectly when directly connected and are very fast. The only reason that you would need a Fibre Channel switch is if you want multiple machines to be able to access the array without using network shares.
    I really don't think that just four drives will give you the performance that you're looking for. In order to get good performance out of a RAID5 you NEED as many spindles as you can get. If you're stuck to a budget if would probably go to smaller drives but get more of them. I think you've already discovered this but if you want to do a RAID5+0, you'll need to populate drives on both sides of the RAID as they are physically seperated.
    As far as I know, you can only get Xserve RAID Drive Modules from Apple as they do some pretty intensive testing on every drive before they ship. You can't even buy empty modules, you can buy blanks but they don't include the required electronics.

  • Xserve RAID Admin Tool 1.5.1 not quite working

    I have an Xserve RAID that's currently at firmware 1.3.2/1.26a according to Xserve RAID Admin Tool 1.5.1. However, when I try to upgrade the firmware to 1.5.1 via the RAID Admin Tool 1.5.1, it just doesn't do anything--it accepts the .xfb file and then...nothing. Quitting out of the the Admin Tool and restarting still shows the firmware at 1.3.2/1.26a. Same thing if I shut down and restart the Xserve RAID from the RAID Admin tool. Any tips? There's nothing stored on the RAID system yet (the array hasn't even been created--it's a blank system) and nothing is attached to it either (I've just plugged in the ethernet links to format it first before I start attaching an Xserve G5 to it). Also, even though the lower controller is showing green and I have an ethernet cable plugged into it, I can't get any info out of it nor can I configure it with an IP address. Only the top controller seems to allow some configuration such as IP address.

    Okay, I've solved the problem.
    Basically, the issue was that the lower controller wasn't seated right despite it showing a green light in RAID Admin. When I went to visually inspect it, I noticed that despite what RAID Admin 1.5.1 claimed, its light wasn't even on, let alone green. And since the lower controller handles slots 8-14 of an Xserve RAID and my slots 8-14 are totally unpopulated (empty) at the moment, it was never noticed. Now that I've reseated the lower controller, everything is visually showing green across the board and the firmware upgrade is proceeding as expected and it has upgraded the firmware from 1.3.2/1.26a to 1.5.1/1.5.1c complete with autorestart of both upper and lower controller modules.
    Basic lesson learned: RAID Admin lies. If possible, visually inspect the box itself!
    Thanks to all who responded.

  • Switching to Xserver/Xserve RAID

    Hi boys and girls...
    I was looking for a little assistance in switching over to Xserve. Let me give you some background info first.
    Were a small studio in London, with only 11 people in-house and the majority working externally whether free-lance, from home or from another country etc. Were mostly Mac based, though 4 machines are those little beige pc things all running XP 2002. At the minute its 1 G5 and a collection of G4 tower's and G4 power book's, G4 cube's and so on. Were all connected to a G4 server running Mac OS X Server 10.2.8 with a very small dual 120GB HD raid thing running Retrospect.
    Our problem is, this system was set up some time ago and were starting to outgrow it.
    What were looking for is a way to backup all of our current work and archive all of our old work. Most users like to work directly off the server as theres so much file sharing between the macs and pc's, directly updating files so there isnt any duplication etc.
    First question, is it possible (and a good/bad idea ?) to have 10-15 users working directly from a Mac server, that stores the archived work for users to reference and also current work which is backed up to tape and duplicated (as we currently have) to another HD?
    Secondly, Is the ideal way to be running things? Is there a more efficent way?
    Finally, what kind of spec should we be looking at? There's such a huge difference between servers, while were willing to invest, we dont want to go crazy (maybe a little) on costs.
    I look forward to your responses and thank you in advance
    Marcus

    There are certainly some drawbacks with your current setup that mean you should make some changes.
    In general, there's nothing wrong with working with files directly off the server, however, 10.2.8 has some issues with multiple users accessing the same files at the same time, so you should look to move to 10.4 ASAP to address that issue, regardless of any other changes you make.
    I am assuming that the remote users don't work this way - uploading/download files as appropriate - it would be painful to work off the server remotely.
    The only real disadvantage with working with files directly off the server is that if a file is changed erroneously and saved, there's no easy backup.
    If the file was copied to the local drive and saved, it's easy to roll back to the previous version by re-copying it from the server, but if that change is saved directly to the server the only rollback involves pulling out Retrospect.
    The other change that would make a difference is installing a gigabit switch and connecting the server to it. Even if all the host systems don't have gigabit ethernet, the extra bandwidth to the server will definitely help.
    As for a new server, 10-15 file sharing users are not likely to stress the server, do you don't need a top-of-the-line configuration.
    You should first decide how much disk space you need. With 500GB drives, the XServe can handle up to 1.5TB on its own, without any additional XServe RAID. However, you might want to consider RAID (using RAID you're limited to 1TB of RAID 5 storage, or 500GB of mirrored storage in the box).
    In addition to your current data usage, consider using an online disk backup where multiple copies of the data is stored on the server itself before (or in addition to) backing up to tape.
    While tapes offer several long-term archive advantages, they really don't work so well for quick restores of a file or two. Having a snapshot of the last couple of days data online makes it trivial to step back a day or so without having to resort to tapes. This may mean, though, that your 100GB of data requires 200 or 300GB of disk space.
    If you do decide than an XServe RAID is the right solution, consider getting it right-sized from the get-go rather than buying it small (e.g. 4 drives) and adding later. While it can be done, adding drives to an existing array is a PITA.
    If you do opt for an XServe RAID, and you don't currently have any rack-mounted equipment, consider using a PowerMac G5 as your server rather than an XServe. While similar in terms of performance, the PowerMac can work out cheaper depending on configuration.

  • Can I move Array from one Xserve RAID to another and keep the data

    I'd like to move a set of disk with an existing Array from one Xserve RAID to another. Can I simply shutdown both Xserve RAIDs and move the disk over, assuming I put the disk back in the same order?

    Yes, you should be able to do this.
    BE SURE YOU HAVE A BACKUP FIRST.

  • Clarification on how to use Xserve Raid and Fibre Channel without xsan.

    First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
    Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
    Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
    I never thought of that. I will try that while I await for your answer, thanks again.

    I have the following setup:
    Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
    Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
    Qlogic Sanbox 5600
    Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
    Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
    Here is the problem.
    The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
    Anybody have any suggestions?
    Thanks

    Are multiple computers accessing the same data on the RAID at the same time?
    If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
    The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.

    Intel Xserve, G5 XServes, XRAID, Promise

    +The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
    This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
    +Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
    Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
    Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
    Hope that's clear,

  • Can't copy files to Xserve Raid

    Hello,
    I'm having serious issues copying files to my work's Xserve Raid. When I try to copy files to it, it stalls for several minutes trying to copy, but making no progress, before giving an error saying:
    "The Finder cannot complete the operation because some data in "filename" could not be read or written. (error code -36)"
    When I click ok, I get disconnected from the Raid.
    Any thoughts as to what could be happening?

    What do your logs say? I'd check your afp (or whatever sharing mechanism you're using) and I'd keep an eye out for any fibre channel or LUN messages that might indicate connection/communication problems with RAID itself. (These might show up as LIP messages.)
    Sounds to me like an underlying communications issue rather than a file sharing issue but without more information it's hard to say.
    Good luck,

  • Xserve RAID lost RAID 5 array on right/bottom controller

    I cleanly shut down an Xserve G5 with an Xserve RAID attached and then powered off the Xserve RAID this morning. I replaced a failing memory module in the Xserve and moved the rack 6". I then powered on the Xserve RAID, waited for a couple minutes until it was fully booted, and then booted the Xserve. When it came up, my RAID 50 volume failed to mount. Upon further investigation, it appears that the RAID 5 array on the right hand disks is "gone". In RAID Admin (Disks and Drives tab), the left side array is visible, but all disks on the right side list status as "OK" and Type: as "Spare".
    Configuration: Xserve RAID with 14 250 GB disks. Each side was configured with 6 disks in a RAID 5 array and one spare. These were striped using Software RAID on the Xserve into RAID 50 and mounted as a single volume. The RAID firmware is currently 1.5 and the Xserve is running OS X Server 10.4.3.
    To summarize today's activities: under Apple's guidance (as this entire system is covered under a Premium Support contract), I swapped the (bottom) controller for the right side, updated firmware (from v1.3/1.20a to 1.5/1.50), multiple resets of both controllers, repeated forced firmware updates, etc.
    Also, I swapped the left set of disks for the right set, and the array from the left set now shows up on the right side, and the missing array from the right is still missing with the disks on the left side. I replaced the disks to their original positions with the same results.
    RAID Admin's Utility "Recognize Array" will not perform any operations on the rigth side disks and Apple tells me that there's nothing further that I can do with it.
    None of this has solved the problem or substantially changed the issue, and the disks on the right side are still missing their associated array. Apple is unable/unwilling to offer any further help except to refer me to 3rd party data recovery services.
    Does anyone have any suggestion at all that might possibly recover the missing array? Is anyone aware of any tools that I might use to recreate the RAID 5 array on the right controller? I was hoping that there might exist some low-level tools with which the disks could be recreated into an array by hand? Are there any commercial products that would work on this? Any other ideas?
    Many thanks for any suggestions.

    Not sure why you swapped the controllers back and forth
    William, I don't think I was clear on this. I swapped the controller with a new controller that I had in a spare parts kit. This was at Apple's request.
    really, RAID is not a backup...
    I'm well aware, but despite my incessant warnings, users will become lulled in to a false sense of security when something "just works" for a very long time. This array wasn't intended to store valuable data that couldn't be lost, but...
    It may be possible for Apple to re-create the RAID set, did you ask AppleCare about the possibility?
    Apple has told me more than once that there's nothing else that they can do for me...and yet I keep calling back.
    I was surprised that this array was lost when there were absolutely no prior signs of a problem and the system was merely shutdown and restarted cleanly. I'm more surprised and quite disappointed to learn that Apple will do nothing else for me (under a Premium Support contract) to attempt to repair a damaged array. When I asked questions about where the RAID information is stored, I received the answers: "I can't tell you that" and "Apple doesn't release that information". I did not get the feeling that they were working with me, but rather holding my hand while they walked me through published documentation.
    I expected that there would be utilities (analagous to filesystem repair utilities) such as RAID Admin's "Recognize Array" that could help repair and recover damaged array data. I think that the lesson that I've leanred today is that I was naive to have expected such a thing without actually having investigated it ahead of time.
    Anyway, thanks for your input, William.

  • Configure Xserve RAID as a single RAID 5 array?

    We just picked up a used Xserve RAID with 14x750GB drives, and we want to configure the entire unit as a single RAID5 array. RAID Utility will let us configure each side as a separate array, but not both sides in a single array. Is this not possible or are we just missing something simple?

    No, each side of the RAID is logically separate so while you can create a RAID 5 on either side there is no way to create a single RAID5 of the unit. You can create a RAID 50 and make the 2 RAID5s into a single volume software RAID 0 by using Disk Utility to join the two 5s into a single volume but that's as close as it comes.
