OT (ish): ATTO raid card and Sonnet drive array won't mount

Hi,
It's slightly off topic I think, but the title says it all. My ATTO configuration tool says all is ok and all 8 drives are fine, but Finder doesn't show the drive array (8xdrives as RAID 5). ATTO support have told me how to manually mount the drives via a command line interface, but I'd really like to just turn the computer on and have them there on the desktop(!). While support is thinking about it, I was wondering if anyone had had anything similar and if they felt it was the OS as opposed to the PCI card? I'm running 10.4.11. Other drives (SATA and FW) mount fine.....
Cheers!
Todd.

Apple RAID Card and 3TB Drives only show 2.2 TB

I tried a 3TB Seagate Barracuda XT drive in the July 2010 Mac Pro (and a Jan 2008 Mac Pro) on the RAID Card that came with the machines (so one is the RAID Card now shipping) and both show a maximum of 2.2 TB with a 3TB drive.
I'm curious if anyone else has tried this with different results. Any luck in getting the RAID Card to see the full 3TB in the drives?
By the way, without the RAID Card, the Mac (OS 10.6.4) sees the full 3TB, but not with it.
Anyone else seeing this?

Okay. Seems Apple didn't plan for or certify 3TB.
However, Apple doesn't support using 3rd party drives. Some do, and in some situations, drives you would think work don't, or they work but only briefly.
When I said read FAQ I was thinking of all the points like this:
Question: *Which drives does Apple support for the Mac Pro RAID Card and the Xserve RAID Card?*
Answer: Only Apple SATA drives and Promise 450GB SAS Drive modules sold through the Apple Store are supported for use with the Mac Pro RAID Card (Early 2009) and the Xserve RAID Card (Early 2009).
Apple 300GB SAS Drive modules are supported with the Mac Pro RAID Card (Late 2007) and Xserve RAID Card (Early 2007).
Drives must be either all Serial ATA (SATA) or all Serial Attached SCSI (SAS) drives. SSD drive modules are not recommended for the Apple RAID Card because these drives use their own on-disk cache and cannot take advantage of the protection provided by the battery-backed cache on the RAID card.

K8n Neo2 Plat Sata Raid 0 and IDE drive - Board won't detect IDE

I have my K8n Neo2 Platinum board configured just fine for 2 WD raptor sata drives in raid 0. However, I need to add more space so I went out and got a Seagate 180gb IDE drive. I plug it into the primary IDE slot and the board won't detect the new hard drive. I have 2 DVD-ROM drives working fine in the Secondary IDE slot. Why won't the K8n detect what is plugged into the primary IDE slot?
Any help would be greatly appreciated!
Jeff

Okay...
First, remove both of your DVD Drives and try connecting the new HD to the Secondary IDE Interface as master. Use 'cable-select'. If the drive then works, leave everything set to cable-select, and try installing the HD as master, and one DVD drive as slave, on the primary channel. Next, set the other DVD drive to cable select, and install it on the secondary interface as a slave.
If the drive is still not detected after removing both DVD Drives, then try installing the DVD Drives onto the primary interface. If they work, then you've most likely got a bad HDD. If they don't... your mainboard may be bad.

Mac Pro RAID Card and Western Digital drives

I'm having huge troubles with these items.
I first installed four WD7500AYYS (Raid Edition) to build a RAID 5 and install Leopard on it. At this point, one of the drives was probably DOA and didn't show up in the bay. I then reinstalled the Seagate that shipped with the machine, then proceeded to create another enhanced JBOD raid with one of the WD drives. After a couple of seconds, RAID utility reported an error (disk about to fail and such). I then tried with another one. The process ended with a kernel panic after two hours, while RAID utility was still marking the drive for enhanced JBOD. That disk never show up again, in any bay.
At this point, I'm left with two WD drives. I can't get past the creation of a RAID set with them, no matter what. Either RAID utility reports an error, or it says the disk has been ejected, or it keeps create the RAID for hours... The later usually ends with a "force quit", or a force shutdown. During these attemps, the RAID card went missing once, then it appeared again on the following reboot. The RAID battery, which was fully charged at first, is now being "repaired" (charging ?).
I then ran AHT to see whether there was something wrong. No errors reported.
Because all four drives were Raid Edition, I thought this could be the root of the problems. So I bought a Caviar SE16 (WD5000AAKS). To no avail. It fails too, in the very same way. And now it no longer appears in any bay.
The last step I took was to remove the RAID card (connecting the iPass connector to the motherboard). Out of the five WD drives, only two RE2 (the two that still show up with the RAID card) do appear in disk utility. But disk utility never ends "writing the partition map" or "preparing for initialization".
By now, I end up with five WD drives that appear to be just dead, as if they were killed by the RAID card trying to RAID them. The only drive that works, with or without the RAID card, in any bay, is the Seagate. I didn't try to fiddle with it though (I'm reluctant to format it just to see whether I can create an enhanced JBOD raid with it).
So the question is, are Western Digital drives compatible with this RAID card ? If they do, then how a RAID card can kill them in such a way while keeping the Seagate alive ?
I'm lost in conjectures. I don't even know if/how I can bring all the WD drives back to life. I'm not sure the RAID card is faulty, I've already lost a lot of time and money, I'm not willing to buy yet another drive to see it fail too, and my Mac Pro is kind of useless as I don't want to spend time on installing/configuring everything I need on a drive that is bound to be replaced by a larger RAID 5 array.
Any help is appreciated. Thank you.

Someone yesterday or Friday, had a system with 4 x 1TB drives and Pro RAID, but in their case, it was determined later Saturday that drive bay #1 was not functioning.
Hopefully these fully retail drives, not OEMs, and I would think they are fine. They are what I would use (Sonnet Tempo only supports RE of the WD drives). Someone else, Danish?, had 3 out of 4 WD drives were DOA.
I've never had trouble buying over a dozen from OWC, so it does seem odd.
If you have SoftRAID 3.6.6 I would use that to zero the first and last 100 sectors, or you can begin to zero the whole drive and cancel at any time, just to check the health of the drive and that it can zero and not produce I/O errors.

http://docs.info.apple.com/article.html?artnum=306231
Originally, only Apple drives were supported. My understanding was that this changed. But the only article I found in KB dates back to Aug '07:
Question: What drives does Apple support with the Mac Pro RAID Card and the Xserve RAID Card?
Answer: +Only Apple drives are supported with the Mac Pro RAID Card and the Xserve RAID Card.+
My understanding that 3rd party retail drives such as WD RE2 750GB, Seagate, Hitachi were supported as well since the article was written - and I can't find where I read that, but sure that I did, as this was discussed in the past.
I'd like to find an official article. Even my friend Google was helpless

MacPro Raid Card w/ SAS Drives is battery required?

We have a MacPro (early 2008) dual 2.8 Quad with Mac Raid Card and 4 300g SAS drives. The battery became an issue early on it was always showing low on start-ups. Now it shows failed. I am now running system with 3 drives striped raid 0. Is the battery required to be replaced? I like this system for the speed it gives us on short HD, using my original media as the back-up. I am a little out of my league with the SAS drives so any opperation tips would be a plus! Thanx in advance....

The RAID card allows for the use of SAS drives or for the use of RAID 5 (which requires checksum calculation on writes and for data re-creation after a failure).
The battery assures that the data will be held in the RAID card's RAM until it can be written to the drives, even if a power failure occurs just after the data are written to the card (but before they are re-written to the drives).
Not using that feature? You don't need the battery.
Not using RAID 5 or SAS drives? You don't need the Apple RAID card. Disk Utility can set up Striped or Mirrored RAID sets.

Raid Card and Multiple Hardrives.

does anyone have any idea if I can use the raid card to use a seperate hard drive to run windows and then use another drive for mac OSX? That way I don't have to worry about partitioning my hardrive. If there is any way to do so I would really like to know. Also any cheaper suggestions for a raid card?

Fact is you cannot use the APPLE RAID CARD and also run Windows on any of the internal SATA ports. Unless you want to play around with iPass or reroute the cables.
http://www.apple.com/support/macpro/
I consider the RAID card more hinderance, and not just in terms of Boot Camp.
http://www.apple.com/support/bootcamp/
Windows 7 is fine, more users probably than use Leopard, and runs well, no issues, and better than Vista even with SP2.

Raid card and scratch disk setup for FCP

Hi Guys
Can anybody tell me what is the correct way to set up a raid card and scratch disk for FCP if you have 3 x 2TB internal hard drives, with the OS on HD1 and drives 2 and 3 dedicated for FCP
Also with this i also have all my documents i.e work stuff, invoices, pictures, music ect from my old windows PC and used to have them stored on HD2 with the Windows 7 OS on HD1 - i have been told that it is fine if i put this on the same drives as FCP is this correct...?
i only ask this as i have been told how to do it in different ways by 3 people......

Thanks John, although i'm rather embarrassed to admit that I am a complete newbie when it comes to technical/computer hardware terms (i.e. I have no idea about different types of disks, other than a HDD and a SSD, or even what the difference is between your media cache and a scratch disk).
This means that after reading all the links you so helpfully provided hasn't done much other than making me feel even more stupid!
The best that I can conclude from what I think that i've understood is that I will use:
Intel 530 Series 120GB SSD for O/S, Programs (and Pagefile?? No idea what this is, sorry)
Samsung 840BW 500GB - Scratch Disk (is this the media cache?) and preview
Seagate Barracuda 3TB HDD - media, projects, and exports
Please tell me if i've got something around the wrong way....
Thanks again.

Apple RAID Card, 4 SAS drives, 1 bootable large striped volume?

I have an Apple RAID card and 4 SAS 250GB drives. I did the migration when I set up the RAID to give me 1 drive for my bootable OSX volume and the other 3 combined into unused unpartitioned space.
But I want all 4 drives combined and striped for one large bootable OSX volume. I'd prefer not to have to reinstall OSX to do this.
Do I need to buy a utility? Can I use Disk Utility or the Apple RAID Utility? I've done searches and read all the help and can't find an answer.

Is it possible to install a third disk (300GB SAS) and to use it as a separate Volume ?
Yes. Of course.
How do I have to set this up using Apple Raid Utility ?
No. A third drive should just appear on the desktop. You only need RAID utility if you want to add that drive to an array, which doesn't sound like the case here.

Raid card issue - missing drive

I have bought some new Mac Pro 2010 Dual 2.93GHZ Xeon (6 core) machine, with Raid Card and 4 2TB drives and then set up a Raid 1 and a Raid 0 on the machine striped for safe&speed as I use the machine for video editing and motion graphics. From the first day, I have issues with 3 machines (out of 5): the raid keeps failing. Both raids work fine, then without warning the Raid Set falls over. Every time it has fallen over, it is usually when the drives and the Raid are not being used. It commonly gives me this type of error - Drive 3:5000cXXXXXXXXXXXXXXXXXXXXX failure detected - Primary disk port unusable, previous drive status was inuse, followed by Drive 3:5000cXXXXXXXXXXXXXXXX missing - Previous drive status was inuse. The drive (Bay 2 usually) in realy mising from RAID UTILITY Tool. After reboot the drive reappears and I can make it Spare, in order to rebuild the volume. In the first instance I thought it's about Power Management, but even after disabling HDD power off, I have the same situation.
Apple dealer is still looking at one machine, but... Did anyone meet similar behaviour?

I'm having the exact same problem, or at least really similar.
I thought I'd configure everything as RAID-0, all brand new drives. Those shouldn't crash very fast.
Big mistake of course... But the weird thing is, in the RAID_Utility it says all the drives are "green" smart: checked and status: good. But it removed one of the disks from my raid. Is there any way I can "plug" that drive back into my raid set? Because the drive is ok, but it's just de-coupled from the set....

Different RAID card and HDDs

Hello -
I did some searches for older posts, but didn't find anything with a definite answer.
I know the Apple RAID FAQ mentions that only Apple drives are supported with the RAID card both some posts have said this is not the case anymore. And there are several posts with people buying new WDs and Seagates for their Pros. So does the Apple RAID card support other drives?
My next question is does the Pro support any other RAID card beside the Apple one? If so, are there any recommendations on a good one? Will it work fine with the Pro form factor and with OS X?
Thank you

Search through http://www.amug.com which reviews most every controller and hard drive, as does http://www.barefeats.com
RAID is a frequent topic, search for userid "mbean" and "RAID" and you'll come across some very in-depth replies.

Mac PRo with raid card shipped with drive not suitable for raid?

Hi all,
I ordered a Mac Pro with raid card and a 1TB hard drive. The drive which came in the computer was WDC WD1001FALS which is not a hard drive rated for raid usage. On Western Digital's site they suggest using WD1002FBYS.
Is the model WD1001FALS the correct drive which Apple ships although one ordered the raid card?

The WD 640GB Blue, and WD 1TB Black are the only drive options for the mac pro; that's what you choose.
The RE3 (or FBYS) is not an option sold through apple. Buying the raid card, is not going to change the drive.
On whether to use the RE3 over the Blacks, it depends on how you will be using it. From what I've heard, the Blacks are enterprise drives themselves; basically with just a less robust firmware (no TLER). If you will have the drives on 24/7 in a raid 5, then yes, RE3 will probably be better. If not, I think the black will suffice; note the blacks are GREAT drives by themselves anyway.
The apple raid card can connect to both SATA and SAS drives internally, however most times people buying the raid card want to use it for SAS drives. There are a lot more cheaper and possibly a lot more stable options then apple's raid card if you are looking to use SATA drives.
Check amug:
http://www.amug.org/
A common problem with the apple raid card is the battery:
http://store.apple.com/us/product/MA849Z/B?mco=NDc1ODczNw
Lastly about enterprise drives, truthfully I don't see the difference really. I have enterprise drives in a 8-drive raid5 config running 24/7 as a server. 2 drives died on me after about 4 months. To top it off, they died within 10 min of each other, crushing the raid to pieces. Granted they were Seagate ES.2's, it's understandable
The boot drive of the server is a stock desktop WD drive and running 24/7. It's been running for almost 4 years straight.

External Iomega Drive Partition won't mount

Hi:
I have a partition on my Iomega external drive that won't mount. The drive has 2 partitions. One I use for back up works fine. This other one is visiable but won't mount. I have run disk utitility and it says everything is fine but says it isn't journaled. It won't let me turn on journaling and won't let me get it mounted, what can I do?

Hi Dennis:
Thank you for your attempt at helping me. I opened Disk Utility and saw the greyed out "video Editing" partition, clicked on it and tried to mount it. It says it cannot mount the volume. I then clicked on the greyed out drive partition and clicked on disk first aid. It gives me the following screen.
Verify and Repair volume “Video Editing”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume Video Editing appears to be OK.
It just plain won't mount but I have in the past been able to see the contents inside and the other partition for which I use as back up for my iMac works just fine so I know the drive is working fine. I just cannot get this partition to mount.
Any other ideas?
Thank you,
Reid

3rd Party SATA raid cards for internal drives?

All --
Apart from the discussion as to if RAID actually benefits a home desktop system, I am wondering if anyone has the lowdown on using 3rd party SATA raid cards to support the INTERNAL hard drives on the Mac Pro series?
My Mac Pro is still slated to be built at Apple and for now I have the minimum memory and HD spec being requested at Apple, with the plan to upgrade the memory and drives from OWC or another vendor.
I've toyed with the idea of utilizing Disk Utility's software RAID features (e.g. RAID 0 for scratch disks, RAID 1 for boot, RAID 0+1 for all else.) I've also toyed with the notion of searching for a hardware raid solution which would allow me to transfer the internal SATA cable runs from the motherboard to a host adapter card for an internal multi-channel experience (with options to create and break mirrors to external devices for backup purposes.)
So....
Has anyone experience or utilized 3rd party hardware raid controllers which can connect to the internal HD bays? Are there limitations to this (ie, does the boot drive HAVE to reside off the internal motherboard controllers, or can an internal hardware controller successfully boot the system) of which ought be noted?
Finally, in the event that a host adapter card cannot drive the interna bays, can anyone give feedback to hardware SATA cards to power external drive bays with support for Disk Utility (to allow RAID1 pairings of internal drives to external snapshot-backup drives)?
Thanks for your time,

I am wondering if anyone has the lowdown on using 3rd party SATA raid cards to support the INTERNAL hard drives on the Mac Pro series?
There are many 3rd party controllers that support the internal HDs if an internal iPass connector is used. The problem is that some are bootable but most are not.
The Areca ARC-1680ix-12 and the HighPoint RocketRAID 4320 are bootable. However, the system cannot be installed via the Apple DVD. Instead the user needs to clone a boot drive with the proper drivers to the boot volume on the controller and then boot from the 3rd party controller.
The other issue I found is that these controllers do not support Boot Camp. If Boot Camp is desired, my recommendation would be to leave the internal HDs on the Mac Pro internal bus intact and use the 3rd party controller for external storage. This method provides four internal bays that are bootable, support Boot Camp and can be used for system backups. I use the 3rd party controller for external storage for large RAID sets and hot swapping hard disks.
With the internal bays intact and external hot swap RAID storage available the user can support Boot Camp, multiple system volumes and large external RAID sets. From my experience using a 3rd party controller with the internal HD bays always has some limitations. The user usually does not realize it unit later when Boot Camp does not work or the computer fails on a system upgrade or the controller does not work at all with a new version of Mac OS X.
Staying with the standard internal Mac Pro bay configuration will be the best configuration to avoid compatibility issues with future versions of Mac OS X. It is rumored that the new Snow Leopard may require 64-bit drivers. If that is the case, I would expect most if not all existing 3rd party controller drivers to fail. Some drivers will be upgraded after a few months while others may not. Having the internal Mac Pro SATA controller intact should at least allow the Mac Pro to boot if my guess about compatibility issues is correct.
can anyone give feedback to hardware SATA cards to power external drive bays with support for Disk Utility (to allow RAID1 pairings of internal drives to external snapshot-backup drives)?
There are a large number of external controllers that work with Disk Utility. Here are some of my favorites.

Workaround for Hardware Raid-Card and Bootcamp

I have ordered my new Mac Pro with the optional raid-card by Apple. Since there are no drivers for Windows XP or Vista available, harddrives attached to the card cannot be used for bootcamp to boot from. But it seems the Apple ships teh new Mac Pros with all drive bays connected to the raid-card. I was wondering if i could bypass the card by detaching one of the SATA-cables and plug it into the mainboard directly to use the first (or last) drive bay for a separate boot drive (WD velociraptor 300 GB) with a partition for Mac OSX 10.5 and Windows XP (each 150 GB) on this drive. I want use the rest of the harddrives attached to the RAID-card for a raid 0 under Mac OSX only. Windows XP will use an external storage case connected by Firewire 800.

Hi,
I believe the iPass cable connects all four hard disks with a single connector. This makes it difficult to remove one bay from the Apple Card. My experience is that you either use the card for all four bays or you disconnect the card and use the stock motherboard SATA interface.
I found using an external RAID box allows me to have all four internal hard disk bays available for boot disk or boot camp use. The external SeriTek/5PM provides my RAID. I can use the HighPoint RR2314 for a five disk RAID 5 configuration or the Sonnet Tempo E4P if I want a RAID created by Disk Utility. Using multiple SeriTek/5PM enclosures can increase the performance.
http://www.amug.org/amug-web/html/amug/reviews/articles/firmtek/5pm/
http://firmtek.stores.yahoo.net/sata5pm.html
If you want even higher RAID performance and SAS compatibility and don't mind spending more $$$ the HighPoint RocketRAID 4322 RAID 5/6 Controller provides amazing performance with the Enhance RS16 JS SAS expander enclosure. The AMUG tests show this combination can provide RAID 6, sixteen disk average write performance of 696MB/sec. and 833MB/sec. read performance.

http://www.amug.org/amug-web/html/amug/reviews/articles/datoptic/rm16_ex8/
There are lots of RAID solutions available for the Mac Pro. However, I find the internal Apple RAID lack of Boot Camp support is too restrictive and higher performance is available from 3rd party solutions at a better performance to cost ratio.
Have fun!
