Reseting my Xserve Raid

Hi
I have an Xserve G5 that provides user accounts with network home directories that are stored on an Xserve raid. When I opened raid admin today it was no longer able to see the Raid's IP address via Bonjour. l have seen a number of threads in which people have had a similar problem that was resolved using the reset button (and a carefully placed paper clip). My question is whether I can safely do this with my setup or will it mean having to re-setup all my home directory sharepoints etc.
Cheers in advance

Hi Lee,
Resetting the RAID controllers won't harm anything. The volume may go offline for a bit, but you won't need to re set up your home directories, etc.
That said, I don't think it should be necessary. Not sure why it's not discovering, but if you have a machine that is connected directly to the RAID, you could open up a terminal and type "ping 255.255.255.255" and you should see a response from the 169.254/16 IP address of the RAID.
Personally, I'd recommend giving the RAID a static IP address after you connect to it the first time. Makes things easier.

  • 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

    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.

  • 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.
    https://discussions.apple.com/message/3330193

    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.

  • 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.
    - Martin
    Xserve RAID (14 250GB disks) on Xserve G5   Mac OS X (10.4.3)  

    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.

  • AFP and Xserve RAID very SLOOOOW

    Recently we have been having problems with AFP pegging the Xserve RAID activity lights. Xserve RAID Disk access is very slow.
    Machine Specs:
    Dual 2.3 GHZ G5 Xserve
    1GB RAM (recently downgraded because of memory problems after a power outage)
    1x80GB Xserve drive module
    3TB Xserve RAID 5
    Xserve RAID has been upgraded to 1.5 FW and has both ethernet connections connected.
    The whole story is we had a power outage last week. The servers all came back up fine. Throughout the day we noticed that the file server was acting strange. We checked server monitor and it said that RAM slot 3&4 had problems. We opened up System Profiler and it reported that modules 2&3 were only 256MB! (These are 512MB modules). We brought the machine down and pulled the modules. The machine is now at 1GB of memory with more coming. The next day the machine was incredibly slow and the RAIDs access lights were pegged. Also something was pulling all free memory into inactive memory. After trial and error I've found that if I turn off AFP the RAID is no longer pegged and the memory goes back to normal. I thought AFP was the problem and did a complete rebuild of the server last night. This morning the same thing is happening. Also the logs show nothing is wrong.
    All of our Macintosh users are Mobile accounts over AFP. We have around 60 Macintosh users. All of our PC users connect using SMB. We have around 20 PC users. All of our network users work off of the file shares.
    Thanks for any and all help,

    Check so that the Xserve RAID diskcache settings are not reset/off.
    I have had to take apart the RAID controllers and putting them back togheter again to alleviate slowness/"malfunction" making a couple of RAIDs operating like normal again.
    I use Helios Lantest http://www.helios.de/ and XRG to measure/stress disks locally and over the network to see if they are working correctly.

  • Connecting xserve to xserve raid - done everything

    Hello,
    I'm having trouble connecting my secondhand xserve to xserve raid.
    - xserve is running 10.8.5
    - i'm screen sharing the xserve
    - I have reset both the RAID controllers with paperclip
    - both fiber channels are connected
    - both controller cards are connected to the xserve via ethernet
    - half the hdds in both sides of raid show red light
    - it has been on for 24 hours now
    Add system in RAID Admin doesn't propose anything, so I have manually entered the ip addresses from server.app>network pane.
    If anybody has any ideas I would be thankful.
    Paul

    There are several possibilities.
    First off, from your screen shot, both your RAID and your host are using the same IP addresses (169.254.192.90 and 169.254.87.107). That's not going to work. However, it's probably not your major problem... let's move down the stack.
    Your interface on the host isn't connected/configured corrected - as noted by the Orange ball alongside the IP address. You need to fix that.
    Second, the 169.254 addresses are somewhat variable, so just because the RAID had that address at one point in time that doesn't mean it still has that address - it could have changed. This may or may not be the case, depending on the link status of the host system.
    If you choose to Add System within RAID Admin, it will search over the network to find nearby, available RAID systems to add. This is usually better than relying on dynamic IP addresses that might have changed since you last configured the array.
    In either caase, focus on the link to your host. Check if you can at least ping the RAID. Use a tool such as tcpdump to see if you can determine the IP address of the RAID (hint: you should see it broadcasting on the network link).

  • XServe Raid Controller Replacement

    My XRaid runs fine, then shows a fault on one of the two RAID controllers. The other takes over, and everything works as far as serving files, but the array attached to the RAID controller with the fault will not allow files to be written or created. Reading is fine.
    If I reset the controller, shut down the XServe (intel), then reboot the XRaid, all functionality is restored. I'm figuring that I need a replacement RAID controller. Anyone have a good source for the RAID controller? Or a better long-term solution?
    Thanks!

    Hi
    You should still be able to order replacement/exchange parts for the XServe RAID via Apple Service or GSX. If you go to your nearest Apple Repair Centre/Specialist with the XServe RAID's Serial Number they should be able to quote for a replacement/exchange?
    Are you sure it's not the FC Cable itself? Have you tried swopping the cables? Do you have another cable you can try instead? Have you tried re-seating the Controllers? Shutdown the RAID, remove the kettle leads, remove the affected controller. If you have a can of air give the inside a good blast and insert the controller.

  • XServe Raid won't mount after drive replacement

    We had a drive go bad on an XServe Raid.  We replaced the drive.  It went through the rebuilding process. Now we can't mount the raid.  The verify in the disk utility is successful but it still won't mount.  What are we missing?

    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.

  • Raid Admin will no longer discover Xserve Raids

    We have 6 Xserve Raids and as of the late I can no longer discover all of them using Raid Admin. I have gone through the reset procedure several times on 2 of the 6, and they are still undiscovered.
    Supposedly that resets them to DHCP (no fixed address) and they should be seen in "Add System". Does not happen. I can still see one Xserve and monitor it; but the rest are lost. I know discovery is changed to Bonjour.
    All volume mount and properly on their corresponding Xserve and appear to be working fine, but I cannot create, monitor, or do anyhting with them. This is really a mess becaue I am trying to add a 7th and can't discover it to initialize it.
    Any suggestions ?

    I am able to see a new Xserve-Raid on a cross-connect cable connecting the Raid to a Powerbook. I am able to format it and am sure that when connected to Fibre-Optic channel that I will be able to format the Raid Disk. Thanks for your good advise.
    I am not sure I will ever be able to see it (the new Xserve Raid) again to monitor or to change, once it is on our real private network. I guess I don't understand why several of the Xserve Raid's have spontaneously dissappeared from the Raid Admin monitor, never to be found again; even when specifying their assigned address (fixed addresses). The controller must have lost the fixed address and Bonjour cannot detect it anymore.
    Has anyone had a similar issue ?

  • Inherited Xserve Raid

    I have an older Xserve G4 with OS 10.4.8 server. I just inherited an Xserve Raid that's about the same vintage. I can't seem to get the RAID Admin utility (1.5.1) to connect to it. It seems to see the hardware, but no info other than name show up in the Raid Admin window when I try to add a system, but never gives me any drive info - or much of any other info. It just says it's gathering info. the components and network lights are red (in the RAID Admin) and the drives-array light is yellow. All LEDs on the front and back of the RAID hardware are green, including the two fiber channel link LEDs. I tried to upgrade the RAID's firmware, but when I click upgrade, it just closes the upgrade window and goes back to RAID Admin which is still gathering info. no reboot. Is there a RAID utility that I need? Can't find one on Apples site.
    Thanks in advance

    Whether you need one or both ports depends on how the RAID was originally configured.
    It may be that even with both ports connected you still won't be able to connect if it's setup with IP addresses that aren't valid on your network.
    You could also try resetting the controllers using the instructions here.

  • Xserve Raid Not Showing all Drives Empty - No Green Lights on Xserve Raid Drives

    I have an Xserve Raid.  I recently set it up with my Xserve server with fiber cables and now when the Xserve Raid system boots and starts all the drives show as empty in the Raid monitor.  Not sure if I have something configured wrong and I think I shut it down incorrectly before I got it hooked up right.  When I first got it I was able to see the lights on all the drives but now it boots but no drives show up at all.  I have fiber cables to the host Xserve machine and the Xserve Raid plugged into the network with only 1x  ethernet cables (not 2 if that makes a difference).  When I try to manage the Xserve Raid all drives show as empty even though all the 500GB drives are plugged in.  Not seeing any green lights when the Xserve raid boots indicates something is up.  I reset the controller cards to stock with the paper clip to factory settings.  Does anyone have any ideas on what to try.  Anyone have this issue?  I haven't found any discussions except one that had a single side of drives go down because of a bad controller card.  My Xserve Raid shows no drives at all.  Any help is appreciated.

    Expansion is a 2 step process: First, you expand the array. Second, you merge the slices. The documentation is clear on step #2, but the GUI doesn't FORCE you to do it. However, it is necessary.
    If you did both steps, try rebooting your host and see if it picks up the changed size. It does work... the usual issue though is growing the file system to recognize the additional size. On Linux, I can't help you.

  • 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!

    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.

  • Left side of XServe Raid disappeared.  Please help

    Hello,
    During the cleanup of a bunch of data on right side of my XServe Raid (two raid 5's with spare, one on the left side, one on the right side), the server became very unresponsive (Windows 2k server), to the point where it wouldn't even shut down. I reset the box but when it came back up the left side of the XServe was gone (showed up as a missing drive in disk manager).
    RAID Admin shows that there is no raid on the left side and shows all drives as spares. I've just completed copying all the data off of the still functional right hand side and can now attempt to recover the left side (if that's even possible?). I saw a suggestion that full power offs and restarts (multiple times) has helped another poster. So far I have powered down the XServe Raid 2 or 3 times without the left side raid showing up. I'll be trying a few more times shortly.
    I believe there is an option to recover the raid in RAID Admin? My XServe has an older version of firmware that does not support the RAID Admin Utilities. I have been nervous of upgrading the firmware and possibly irreversibly losing the raid if it isn't already irreversibly gone.
    Can anyone offer any suggestions?

    No luck on the reset, both via Raid Admin and the reset button on the XServe Raid.
    A restore of most of the data has completed onto another storage device.
    I can see a power spike or something wiping out the config of both arrays, but to have only one side just disappear and with no way to re-read the raid configuration from the drives, I can't trust the XServe RAID anymore and we won't be going back to using it.
    I certainly appreciate you taking the time to offer a suggestion Camelot!

  • 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.
