RAID card and temperature spike

We have two dual G5 Xserves, in different locations. One of them, newly installed, has the RAID PCI card and three 500 GB disk modules, and that's the machine on which Server Monitor is currently reporting a temperature warning at the PCI card sensor, at about 135 degrees. The fan on that section is running at about 12000 RPM.
The other dual-G5 Xserve doesn't have the PCI card, and runs about 25 degrees cooler in that enclosure section. Its comparable fan runs at about 4000 RPM.
There were some potential ventilation issues with the hotter machine which we corrected last week, but neither the temperature nor the fan speed have gone down at all. Is this a normal symptom of the RAID card, or does it sound indicative of a different problem?
Thanks.

There's definitely something amiss. None of my servers with RAID cards run significantly hotter than those without.
There's either something wrong with the server causing it to overheat, something about the environment (lack of air flow, A/C, etc.), or something as benign as a faulty temperature sensor.
It is something you should try to fix. If you're confident about the environment then call Apple regarding the temperature sensor.

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.

Windows 7 is fine, more users probably than use Leopard, and runs well, no issues, and better than Vista even with SP2.

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.

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

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 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.

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!

Need help with RAID Card and degraded Raid-5 errors

Dear all,
I recently purchased a used Apple RAID card for my 2008 Mac Pro 8-Core. The installation went smooth, the card was immediately recognized and the battery reconditioned within one night.
So I started setting up a Raid Set with the 4 identical drives which I already used before as a software Raid. But each time the Raid Level-5 Volume is created, somewhat later the status turns red and the Raid is listed as "degraded"!
A closer look at log reveals:
+19:42:54 Drive carrier 00:01 inserted+
+19:42:27 Background task aborted: Task=Init,Scope=DRVGRP,Group=RS1+
+19:42:27 Degraded RAID set RS1 - No spare available for rebuild+
+19:42:26 Degraded RAID set RS1+
+19:42:22 Drive carrier 00:01 removed+
+15:10:57 Created volume “R1V1” on RAID set “RS1”+
So it seems that the drive from Bay 1 somehow gets lost (removed) a few hours after the volume is being created and anysoon later it's being "reinserted"...
Of course, the drive is NOT removed, nobody touched the Mac Pro! Also I did the same procedure 3 times and the result was always the same.
I also tried setting up JBOD and different RAID levels which do all work without a problem. Only when choosing RAID5 (what I intentionally bought the card for), the problem reappears
Anyone any solution or hint for me concerning this problem? Many thanks in advance!

One drive completely broke down later. Replaced that drive and since the problem's gone!

XServe with hardware RAID card and headless install

Today, while trying to remotely install Mac OS X Server 10.4 ("Tiger") on an Apple XServe G5 with hardware RAID card, I discovered that it did not report the IP address of the server (booted from CD) with the sa_srchr command as it did with Mac OS X Server 10.3. With Mac OS X Server 10.3, I could boot the server from the CD, use the sa_srchr command from a remote machine to find the IP address, ssh into the server and user megaraid to create or recreate the RAID volumes using the internal drives in the server.
When I boot the XServe from the Mac OS Server 10.4 CD and run the sa_srchr command from a remote computer, I get "No Longer Used" in the place where the IP address should be (as it was in 10.3 Server and as it is described in the current, 10.4 Server, "Command Line Administration" manual).
Example: localhost#2xCPUFormat#No Longer Used #xx:xx:xx:xx:xx:xx#Mac OS X Server 10.4#RDY4PkgInstall#3.0#512
Just as an experiment, I threw the Mac OS X Server 10.4 DVD into an iMac G5 and booted it. Using the sa_srchr command, I get the same "No Longer Used" where the IP address should be.
Does anyone know:
Is this a problem with the original "Mac OS X Server 10.4.0" installation CDs? Do I need 10.4.1, 10.4.2 or 10.4.3 CD/DVD media?
Has this functionality been removed from Tiger install discs? Is there another way to create the RAID volumes?
I know that I can use the Mac OS X 10.3 Server disks to work around this, but it doesn't seem like I should have to...

Are you sure you have the 10.4 Admin Tools installed on the 'client' machine? I've seen this happen when trying to set up a 10.4 server from a machine with 10.3 Admin Tools installed. Try deleting the Admin Tools from your client machine, and re-install from a 10.4 DVD.

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.
What do you need your setup for though is the first question. And whether $799 is the best bet, first.

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.

Areca Raid card and Udev strangeness

I rebuilt my system with a custom kernel to use the Areca ARC1210 Raid drivers. The kernel built and booted without any problems, and dmesg even shows the raid driver initializing:
ARECA RAID ADAPTER0: FIRMWARE VERSION 1.38 2005-10-4
scsi0: ARECA ARC1210 PCI-EXPRESS 4 PORTS SATA RAID CONTROLLER
Driver version: 1.20.0X.12
Vendor: Areca Model: ARC-1210-VOL#00 Rev: 001
Type: Direct-access ANSI SCSI Revision: 003
and later
SCSI device sda: 1249999872 512-byte hdwr sectors (640000 MB)
sda: sda1
sd 0:0:0:0 Attached SCSI disk sda
libata version 1.20.0 loaded
However, as it is booting it displays
mount: special device /dev/sda1 does not exist.
The /etc/fstab entry is:
/dev/sda1 /smnt/raid reiserfs defaults 0 0
It may or may not be worth noting, but when I go to mount it with udev (mount /dev/sda1) it fails with "wrong filesystem". But if I "mount /dev/sda1 /smnt/raid" it works just fine.
Also, /dev/scsi/host0/bus0/target0/lun0/part1 is symlinked to /dev/sda.
Am I missing something from my kernel? Or is something compiled as a module that shouldn't be?
EDIT: I forgot to mention, the custom kernel is not an initrd kernel, so I don't think the wiki page applies.

FUBAR wrote:If "mount /dev/sda1" doesn't work, I think your /etc/fstab isn't correct: mount reads /etc/fstab unless you use a "full" mount command like your "mount /dev/sda1 /smnt/raid".
You were correct on one count, thanks. I had a line
/dev/sda1 /mnt/usb vfat user,noauto 0 0
earlier in fstab to mount my flash drive .
It does mount with "mount /dev/sda1" now, but it still produces the same error on boot, even though it seems to recognize the card at the beginning of dmesg. I would write a script to mount it before mysqld at boot, but I'm afraid that I'm missing something that will come back and bite me later. Is there some udev subtlety that I'm not catching?

Hello (hopefully someone can shed some light on my issue)
I own as above a MAC PRO (Early 2008) this has a RAID card installed along with two 15k.7 cheetah hdd (320gb) and a spare drive, (which i made a regular drive)
a while ago i had to replace the RAID card battery, so i did this, over a year later the same thing happened again, but as previous just left it and the system seemed fine for ages, until last night i was working in PHOTOSHOP and everything just froze and the screen kind of appeared GREEN, could not do a single thing. So restarted the mac, this time grey screen for ages and a message appeared, (macs version of blue screen) (see attached).
I restarted the machine and this time a flashing question mark folder!
could not do a thing.
so i found my copy of snow leopard and got the computer to run this and at least launch the DISK UTILITY and (Interestingly in the drop down menu RAID UTILITY was also in the menu) but it did not matter which utility i used the (RAID or DISK) neither could see any of drives, just the dvd drive.
so looked around on you tube and various forums and discovered if i take out the RAID CARD and re-plug the main lead from the RAID card back in to the LOGIC BOARD I would be reverting the MAC to a normal regular non-RAID computer.
After performing this HARDWARE task and inserting all three HDD, and running the DISK utility from the drop down menu via the SNOW LEOPARD disc.
(interestingly since the RAID card had been removed the RAID UTILITY from the drop down menu no longer appeared). running disk utility I can now only see the regular (spare) hdd and DVD Drive, but the two RAID HDD , again, still do not show up DISK UTILITY?
O.K. so i could chuck out the RAID card (AND RAID HDD) and just go with a regular set-up, and run a back restore from Time Machine on a NEW hdd purchased.
but what is wrong with the RAID, is the card at fault or are both HDD used for the RAID knackered? can i perform any tests, to see whats what?
thanks for your help in advanced.

hello people, the issue was in fact the GRAPHICS card nothing to do with the HDD or RAID system ( although this did cause issues with the RAID system it basically lost its way) below is my replay to another similar problem some one else had!
working in photoshop and then everything stopped working and the lot froze! only option was to force shutdown (via button).
and try to restart, hoping all was fine, this was not the case :-(
I had the added issue of the RAID card system, that i have, this was confused to say the lease and would not behave or work, causing the start up to hang.
so i thought the HDD must be bust and the root cause. ( but soon learnt it was not the cause )
...bought a new HDD removed the RAID card and replugged the cable from RAID card into LOGIC board, ( making the computer act like any normal non-RAID system). I managed to install the OSX, using the snow leopard disk way. once the mac was running, i started to notice the screen would flicker and started to see 'artefacts'. so i started to reveal my symptoms to the web and forums and soon discovered that my graphics card could be the issue all along?.
(nvidia geforce 8800gt 2x dvi).
I read up on that a fix, could be either A. reply the thermal paste, as the card could be over heating or B. stick the card in the oven trick.
Tried option A. first and nothing still issues, so last night took the plunge carried out option B. and ta da it worked! i even managed to run
from my new HDD my lasted install OS X, absolutely fine. I then thought, maybe i could repair my RAID so replugged all the HARDWARD back in and
carried out a disk repair and disk permissions on drives( took a small amount of time), via the SNOW LEOPARD disc - (Disk utilities) and this worked and now have my system working as it was just over 6 days ago.
what was the cost to get this? bought a new hdd so 40.00gbp and thermal paste and cleaner kit ( your still need to do this ) search video card trick on you tube.
and renew thermal paste, approx 15.00gbp, technically i don't need the new HDD, but it was all part of the trial and error way i went. ( i do have extra storage as a result!)"

My Caldigit Raid Card problem and..

Hi everyone,
Recently I purchased a Caldigit Raid Card and Installed it to slot 3 in my 8-core Mac Pro(Early 2008).
But, my Mac Pro is making a loud fan noise.
According to Caldigit, if Mac Pro's iPass cable is not properly seated to Caldigit Raid Card's J18 Mini-SAS connector, there will be a fan issue that he's experienced.
But My Installation was absolutely correct and my Mac Pro is still making loud fan noise.
I'm not a novice for such a installation.
I sent several e-mails to Caldigit's Online Reseller in the USA, But they reject the refund.
They said that it is a special order, so it cannot be returned for an exchange for other parts.
But, They don't let me know about a special order before buying the Raid Card.
Also, They said that the product is not damaged nor broken, You just have to make sure it is installed properly. If you decide to return the item, there will be a restocking fee charge.
Really, I can't get refund from the Reseller?
Is it all is my fault?
Here is Asia, I can't go there.
Please give me some advice.
Thank you for reading.
p.s. I'm sorry for my poor englsih and this inconvenience post..

My suggestion is contact CalDigit directly. That is a very new product, not many users will have enough experience to assist you. CalDigit has a good support staff and they will help you out. http://www.CalDigit.com/contact.asp

Apple Raid Card, multiple drives and volumes

Hallo,
my xserve (early-2008) has an Apple Raid Card and two 300GB SAS-drives installed (mirroring).
Is it possible to install a third disk (300GB SAS) and to use it as a separate Volume ?
Disk 1 (300GB SAS) - Apple Raid Card mirroring: Volume 1 (300GB)
Disk 2 (300GB SAS) - Apple Raid Card mirroring: Volume 1 (300GB)
Disk 3 (300GB SAS) - Volume 2 (300GB)
How do I have to set this up using Apple Raid Utility ?
Thanks for your help !

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.
