Apple Hardware RAID 5 - Switch to 2GB HDD

I have an Intel Xserve, Apple RAID Card, 3 Apple 1TB HDD, RAID 5 configuration, 2 Volumes. I need to switch out the drives for 2TB HDD because storage is running low. What is the best approach with the least risk?

Your only safe option to migrate a RAID 5 array is to back up the data, build the new array, then restore the data to the new array.
You might get away with breaking the RAID (i.e. removing one of the drives/ADMs and replacing it with a 2TB drive) and copying the data off the degraded RAID, but I wouldn't recommend it.

You can buy and install the hard drive you want to. However, on Late 2009 and newer iMacs the temperature sensor is in the hard drive, so if you replace it with a hard drive that has not got a temperature sensor you will have serious fan problems.
You have got an Early 2009 iMac, so do not worry about this. You can buy a hard drive at OWC > http://eshop.macsales.com/shop/hard-drives/3.5-SerialATA/ Follow these steps > http://www.ifixit.com/Guide/iMac+Intel+24-Inch+EMC+2267+Hard+Drive+Replacement/9 028

Wanted: Apple Hardware RAID Card for Xserve G5

I have some questions regarding the original internal Apple Hardware RAID Card for an Xserve G5.
1) Does it support native hardware RAID level 5?
2) Does anyone know where I can find one of these cards? I can't even find them on eBay.
3) I heard this card is based on an LSI board. Which model? Has anyone had success using the non-Apple version of the same model board in an Xserve G5 with internal Apple Drive Modules?
4) How do you hook up this card? Do I put it in the PCI slot and move the SATA cables to it or does the presence of the card just automagically take over the drives?
Thanks for all your help!

I heard this card is based on an LSI board. Which model?
Camelot is correct that this card is based on (is) the LSI Logic MegaRAID SATA 150-4 card:
http://www.lsi.com/storagehome/products_home/internal_raid/megaraid_sata/megaraid_sata1504/index.html
However, it has custom Apple Firmware to support booting by a PPC Xserve G5 rather than a PC. Apple also provides a ported version of the LSI Logic "megaraid" program to manage the card.
There is a bug (well, at least one) in the Apple Firmware version that was fixed by LSI Logic in its PC version subsequent to Apple's branch off of the LSI Logic code tree for the firmware. Specifically, the card sometimes doesn't fully flush its write caches before it disconnects from the drive buses on graceful power down (doesn't happen on restart). Only known workaround is to turn off the write caches for all LUNs. I turned in a RADAR report (RADAR ID 4350243) under our support agreement back in November 2005, but no action since. I follow up every so often, but clearly this EOL product is not a priority.
Has anyone had success using the non-Apple version of the same model board in an Xserve G5 with internal Apple Drive Modules?
Won't work without the Apple firmware. Apple doesn't distribute the firmware. Been there, done that. Our Apple Hardware RAID card failed in an odd way shortly after installation - it still functioned as a RAID controller once booted from another drive, but you couldn't boot from it. believe that the firmware became corrupted, and that it could have been fixed by flashing the firmware using the "megaraid" program, but Apple Support didn't have a file to flash it with, so it was handled by an RMA exchange.
RAID 5 performance is degraded with the write caches off, but our load is not heavy. I guess you could script the turning off and flushing of the write caches prior to shutdown, and turn them back on again during the boot sequence, but you'd really have to be careful to handle things like restart to CD boot, etc. We value our data more than speed.
This was a very difficult bug to troubleshoot, because the RAID 5 made the mystery garbage blocks from space very hard to find repeatably. Finally came up with a repeatable test case. Fortunately, discovered while testing the Xserve prior to deployment, so no valuable data was lost.

Anyone heard or seen an apple hardware error code 4MOT/4/40000003:HDD-1255 ?

i just did an apple hardware test and this is what i got. my imac running slow. it hangs and stutters often.

It may mean the hard drive is failing or has failed but try den.thed's suggestions here > https://discussions.apple.com/thread/2466535?start=0&tstart=0

Apple Hardware Test error 4MOT/4/40000003:HDD-1211

Did extended hardware test......got this error 4MOT/4/4oooooo3:HDD-1211

Apple does not publish their error codes, however the HDD indicates it's a hard disk related error. It could be the drive, a fan sensor, a HD fan, etc... Before you do ANYTHING and I mean ANYTHING backup and then take the machine in for service immediately.

Using a Mac Pro w / Apple Internal Hardware RAID Card?

Anyone using a Mac Pro with a Apple Hardware RAID Card 2010?
( I have a 12 Core )
Is it worth the $600-700 ?
How much faster than the software RAID 0?
I see Hamm's RAID tips chart .. but it doesn't include such options .. plus it is based on a PC system.
Any tips would be great ..
I find many areas where the application is slow / unresponsive .. and I'm not sure where the bottleneck is ... Maybe the hardware RAID will solve it?
I'm really am impressed with CS5 .. it would be even better with some adjustments .. but I am absolutely disappointed with sluggish performance on my top-of-the-line Mac Pro 12 Core.
This is not what I expected for a $8,000 machine.
Some users says that the port of CS5 for the Mac has taken a back seat to the Windows version at Adobe.
I can't imagine that Adobe would not put 100% effort into Mac products.
Go Team!!!

I have a 2009 Mac Pro 3.33GHz Quad core w/ Apple RAID card, 16GB RAM from OWC, and Apple's Radeon HD 5870 GPU.
I have RAID 0 set across 3x1TB drives internally, and the standard 640GB drive for OSX and all program files. I set all video assets, renders, previews and such on the 3TB RAID.
This seems to work wonderfully. I built this system specifically to edit a feature film shot on P2 DVCProHD, and I've been impressed with how it handles it. This was all built prior to CS5, which took me by surprise. Had I known nVidia would become such a problem for Apple, I would have built a PC, but that's another story.
I just started a new project in CS5 on the same system, this time using H.264 video from my Nikon D7000, and so far, it seems to play just as nicely, despite not having hardware acceleration via CUDA technology. Yellow bars on top, even. I haven't had any problems with clips taking a long time to populate on the timeline or any of that, so perhaps the RAID card helps there.
All this aside, I've already decided to upgrade my RAID for another reason. Right now, my backup is performed via an eSATA-connected external drive through a PCI eSATA card. After every edit session, I dump everything on the RAID onto the external drive, and it goes much faster than the old FW800 transfer used to. I'm about to replace my Apple RAID card with an Areca card and set up a 4-bay RAID 3 via an SAS connection. This will allow for excellent data throughput while offering more security than my current RAID 0 / manual backup system, and free up the internal drives for backups, exports and render files.
I believe in hardware RAID, but I'm not as knowledgeable as Harm and others are about it. I had my Mac built to order with the Apple RAID card, so I have no experience using Premiere with a software RAID. Due to my smooth experience using it, I think it was worth it, but plenty of people say the Apple RAID card is rubbish, and to go with Areca or Atto cards. I didn't know about them until after I built my system, and even though it will cost a couple thousand to upgrade my RAID from this point, I expect to have an even better system than I already have.
I hope this helps, and feel free to ask any questions I didn't address.

Xserve G5 won't boot off Hardware RAID partition

I'm running an Xserve G5, 2.0 GHz single processor, OS X Server 10.4.5 with an Apple Hardware RAID card with 3 500GB drive modules in a RAID 5. The RAID is partitioned into two partitions, one for the system and one for data. After installing a video card, the Xserve will not boot off of the system partition on the RAID. It will boot just fine off a clone of that exact partition on a firewire drive, which is how I have it functioning at the moment. I have tried erasing the system partition on the RAID and re-installing the Server software but whenever I try to boot it it gives me the flashing folder Icon. I have tried resetting the NVRAM as well as restoring the functional backup of the system to no avail.
Any ideas? (I have run disk utility, DiskWarrior, repaired permissions etc.) I also checked the status of the RAID and it is in optimal condition. The data partition seems to be just fine and the system partition seems normal when booted from the external drive.

Harry, I just saw your post. I went through the same pain last fall, and it WAS resolved through Apple Support, but you aren't going to like the solution. Simply as background, during the pre-deployment testing of our Xserve, we were having problems with the Apple BTO SCSI card (really, an LSI Logic 22320) and swapped it out with an ATTO UL4D. Something in the card removal/replacement caused our Apple Hardware RAID card to go into the same mode as yours, where it would work fine as a RAID 5 (two LUNs, 50 GB and 417 GB, over 3x250 GB ADMs) but would not boot. Apple Support and I concluded that something had become corrupted in the firmware or boot code on the Apple Hardware RAID card, but they did not have a file to use to flash it, so they swapped out the card under our support contract, and that fixed it. I still believe that, if I had had a file to flash the card with using the megaraid command, that the original card would have been fixed. FYI the new card has Firmware Version: A131, BIOS Version G117, the old card had Firmware Version: A130, BIOS Version G117. Completely unrelated to this, I've had a RADAR bug report (RADAR #4350243) open since last November that the Apple Hardware RAID card fails to fully flush its write caches on graceful power down. I've got a test case that is 100% reproducible, causes mystery garbage blocks from space. I'd suggest that you turn the write caches off on all LUNs on your Apple Hardware RAID card as a workaround until this is fixed. LSI Logic (the Apple Hardware RAID card is a rebranded LSI Logic card) found and fixed this bug on a later firmware rev from Apple's version. No update is available yet from Apple.

Xserve G5 Hardware Raid Cable - Cable, SATA RAID Card

Anyone know were I can pick up 3 of the hardward raid cable's that are for the internal raid card? Cable, SATA RAID Card

When ours failed (became intermittent when disturbed), it was replaced by Apple Support under our Xserve AppleCare Maintenance Agreement - they overnighted one to me.
In case it helps, the Apple Support part number is 922-6343. the one that you DON'T want (the short cable that is removed when you have the Apple Hardware RAID) has the part number 922-6329. Any Apple service provider ought to be able to order one for you.

Thanks - Even though I'm years out of warranty I got chat help from Apple (I said they should help me since the codes aren't published.) We covered three different questions, and although I didn't get a specific decoding of the error code, I got confirmation of what other comments here imply - it might have helped that I indicated I'd already been here - and useful links to how to do back ups, including to CD(s). (I don't have a lot of data on this computer yet)
Now I need to figure out how to decide how hot-to-the-touch is "too hot" for the metal frame at the top of the iMac to decide whether I'm getting adequate fan performance or insufficient. While chatting I initially reported it was cool at the bottom and warm at the top. Apple hadn't asked, but their response prompted me to feel it again, and I'd say the top was hot, not warm - I updated but Apple didn't comment further except to conclude after addressing the other questions that I should take it in for further assessment - don't really want to bother with that.

Apple Hardware Test on a late 2008 MBP new HDD

Hey Community!
I own a Mac Book Pro - Late 2008 shipped with OSX 10.5.5. Currently I a new 500GB HDD and a 265 SDD are running in my MBP. The Super Drive is in an external USB Housing. Current OS X is version 10.7.1.
I need to run the Apple Hardware Test, because sometimes the system seems to freeze for at least 30 seconds.
What I've already tried:
*) Holding down "D" at the startup -> nothing happens, normal startup
*) setting start volume to external fire wire optical drive, insert 10.5.5. Installation disc, restart, holding down "D" -> startup with installation wizard
*) same with 10.6 Installation disc
*) same with choosing the Backup Partition when holding down "Alt" at startup and then pressing "D"
Always, I was connected via WIFI and Ethernet.
Can someone give me an advise how to run the Apple Hardware Test, or how to reinstall it on the new SDD Harddrive, where my system is mounted?
Thank u and greetings from Austria
Claudio

Try using your disk utility to read the drives. I'm not at my computer now but if you go into utilities->disk utility you might be able to solve it from there.
Also try holding down the C key on boot or esc.

Apple Hardware Test: HDD

Hello there,
I own an iMac 27" (late-2009).
A few days ago, when I pressed the power button (voilà), it returned my a kernel panic gray-screen, with ACPI driver error log.
Just tried to (archive) install the OS X (Snow) again but no success. Then, formatted and seems to workin' good.
2 days later, same error... But Archive+Install worked fine.
Today I've fired the Apple Hardware Test and it showed the following error:
4MOT/4/40000003: HDD-1278
I've done my insanely Google search, but no success.
Does anyone knows what means this error? May I have to change the Hard Drive Disk ?
Thanks so much,
-D

For the 27: Optical drive 998 rpm, hard drive 1100 rpm and CPU fan 938 rpm
There are some temps reflecting computers mostly at idle in this thread. They could go somewhat higher.

Unless you see some really wacky HD fan speed, can't really tell whether it's the drive or the HD fan. Needs to be diagnosed by Apple or some tech.

The error code 4MOT/4/4000003:HDD-1393 has shown up from the apple hardware test. What should I do about this?

My iMac has been running a little hot, it was suggested to run the Apple hardware test (AHT), as heat can cause problems witht he hard drive.
The AHT revealed the error code 4MOT/4/4000003:HDD-1393 which I assume means a hard dtrive problem. But, what do I do. Is this a critical error or a minor fault. Everything is running as normal, but the machine is getting a little hotter than usual.

This indicates problem with HD fan.
Exact nature of the problem is only known to Apple.
We have no way to interpret this error code.
Keep a backup of your data.
When you get a chance, take the Mac to the nearest Apple store to have it tested.
Best.

2008 iMac running beautifully untill recently. Screen glitches and freezing. Apple Hardware test showed error code 4MOT/2/40000004:ADD and I have not seen others with this code. Guessing it is a fan issue based on the ODD and HDD error codes

computer felt hot and while running apple hardware test the screen glitches covered the screen and it froze. Now computer wont boot up. Again AHT code is 4MOT/2/40000004:ADD and I have just seen ODD and HDD codes discussed on other threads.Those were hardrive or superdrive fans, so I am guessing this is a fan issue and then it fried by graphics card. Any help as to whether this is game over or worth repairing would be very appreciated.

You need to take it to your local Apple Store or AASP for a professional evaluation. Apple does not publish the codes from AHT, you can Google the code you got and see if you can determine what it means however the best method is to let a pro handle it.

Hardware Raid 1 with 890GXM-G54

I have just built a new system with Win 7 Pro and the 890GXM-G65. I have a SSD for the boot drive, I'm using ACHI for the SDD. Trying to get two identical HDDs setup in hardware RAID 1 for data storage. I have loaded the AMD RAID drivers from the MSI site. I setup the array from the BIOS by switching out the ACHI option to RAID. I switched back to ACHI so the system would boot off the SSD.
In Win7 Pro, I formatted the drives and indicated a mirror. Am I only getting a software non-bootable RAID solution? I would like to use a hardware RAID if at all possible.
Any suggestions would be greatly appreciated.
Thanks,
drob9876

When you switch back to AHCI, the controller is no longer in RAID Mode...

Well, first of all, 99% of all chipset integrated RAID Suppport solution are soft-RAIDs and no true hardware RAID Solutions. In any case, your controller needs to remain in RAID mode to properly support the volume your created.

Macintosh shows only 150gbs free space,hardware raid is not found/properly installed.what should i do?i am using os x 10.6.8

i am currently having the problem of macbook pro having insufficient space.When i check my macintosh HDD,the devices indicated that there is only 150gb of free space.however,when i went to check "about this mac" on my top left hand corner of the desktop,i can not find any hardware raid.
anyone can provide a solution to this please?this macbook was reformatted and currently using OS X 10.6.8 and there is no more iOS for it to update already.

Please explain. What RAID? internal dual SSD? external ?
TimeMachine backup waiting to be copied?
