Dying Batteries on Mac Pro RAID card

We are using three of these cards and two of them have completely defunct batteries. I am not sure why this happens considering that we have only used them for approx 6 months. The life of them is remarkably short for a rechargeable.... Due to a number of complicated reasons, our warranty with Apple is out so we are not able to do this as a warranty claim but I don't seem to be able to find a means of purchasing these apart from a 3 month wait here in Macau. Does anyone have any advice on where I should go from here. Of course, they operate fine without the batteries but we need them as a form of redundancy...

Hi
Welcome to Apple discussions
You can either try contacting Apple HK to purchase new batteries, is that who said it was a 3 month wait?
Or

  • Is the Apple Mac Pro RAID card (v 2.0) compatible with the Mac Pro (v. 1.1)?

    Hello,
    Just wondering if any of you experts know if the Apple Mac Pro RAID card (v 2.0) is functional with the Mac Pro (v 1.1)?
    I have an original Mac Pro and a new (black) Mac Pro RAID card. I would like to know if I can get any functionality.
    I initially thought that the only difference was that the later RAID card did not have the same limitations on the HDs. I am aware that my original Mac Pro has a SATA II bus rather than a SATA III bus- but I am hoping this will not present any issues other than speed.
    I am currently using Disk Utility for a striped software RAID (0) but would like to move to a parity hardware RAID (5); hence the purchase. If this isn't possible I'm not overly concerned as I managed to get hold of the RAID card for next to nothing so thought I would take the chance.
    Any feedback would be appreciated as everything I've dug up online over the past few days has been a little inconclusive.
    Julius.

    The black-substrate card requires a 2009 or later model, and works only in slot 4, which has a special connector for it there.
    The blue-substrate card requires the ipass cable and connector feature in the 2008 and older models.
    These cards are both showing their age, and limit drive size to 2.2TB each. Their data-backup batteries have been extremely troublesome. You should probably look at other alternatives as well.

  • Sleep or Shut Down with Mac Pro RAID Card?

    I'll be gone for a four-day weekend trip, which is longer than the 72 hours claimed for the Mac Pro RAID Card battery. If I shut down and come back four days later, the battery will presumably be discharged. What will happen when I restart?
    Asked another way ... is 72 hours the maximum amount of time that the computer should be shut down or do I simply restart and wait for the battery to recharge and the write caches to be re-enabled?
    The FAQ for the Mac Pro RAID Card http://support.apple.com/kb/HT1346 talks around this issue, but doesn't say whether it is a good or bad idea to allow the battery to discharge for "... any length of time." Please review the appended excerpt from the FAQ and advise on whether I should sleep or shut down.
    Regards,
    iPhoton
    Question: Why does RAID Utility show a yellow light and report the status "Write cache disabled"?
    Answer: The write cache is disabled automatically so data cannot be written to RAID volumes when the battery charge is not sufficient to back up cached data for 72 hours. This message is normally encountered when a RAID Card is used for the first time, when the battery enters a conditioning cycle once every three months, or when a computer with a RAID Card installed is shut down for any length of time.
    If your RAID card's firmware is M-2.0.3.3 or later, or E-1.2.2.4 or later, you can use RAID Utility to force-enable the write cache while the battery conditions itself. Warning: If you enable the write caches before the battery is fully charged, you might lose some data if the power to your computer is interrupted.

    Thanks to everyone who replied to my message. I did a proper backup and normal shut down on Wednesday night and restarted on Monday morning. That was over 100 hours later and certainly more than the battery is specified (72 hours).
    When I restarted on Monday morning I noticed ... no change! The battery was fully charged according to the RAID Utility, I received no warning messages, there were no new events in the RAID Utility log ... it's as if the extended shutdown never occurred.
    So, an extended shutdown appears not to be a problem and I won't worry about it again, not even on my next extended shutdown for three weeks at the end of the year.

  • 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.

  • Leopard/Bootcamp/Mac pro RAID Card

    The last two bullets in the "More Info" section of Apple's Mac Pro RAID card read as follows:
    • The Mac Pro RAID Card is required when selecting 15,000-rpm SAS drives.
    • The Mac Pro RAID Card supports Mac OS X only.
    Five Apple tech reps have told me I can run Leopard on a striped array of three 300GB SAS drives and then, via Bootcamp, use the fourth independent 300GB SAS drive to run Windows XP. I ordered a $10,000 G5 tower on this premise and now, today, a sixth Apple tech rep tells me it cannot be done. Each time I've called, I get a somewhat different answer. Does anyone have actual experience with a G5 such as this? Is there a third party RAID card that will work? If necessary, I still have time to cancel my order. Why would Apple build a RAID card that is not compatible with a most important feature of Leopard--Bootcamp? I don't understand their philosophy. They seem to work at biting the hand that feeds them.

    Kappy, thanks for taking time to try to answer my question. I'll state it more clearly.
    At this moment I'm typing on a 3 GHz Dual-Core Intel Xeon machine with four 500Gb drives. Three drives are configured as a RAID 0 Volume running Leopard. The fourth INDEPENDENT drive is partitioned via Bootcamp into two bootable volumes--one with Leopard and other with Windows XP Professional. For the new machine I would like to purchase, I never intend to run Windows from a RAID volume. My beef with Apple is that their high performance 15,000 rpm SCSI drives require their RAID card to function, whether it be in a RAID set or independently. Their interface to the motherboard is through the RAID card. Apple has not written Windows drivers for their RAID card. Consequently, if I intend to run Windows on their latest Mac Pro, I cannot install the high performance 15,000 rpm drives. I simply would like to configure the new machine the same as the one I have now, which is three drives combined in a RAID 0 array running Leopard, and the fourth drive remaining a stand alone for Bootcamp to partition into two bootable volumes--one with Leopard and one with Windows XP.
    In summary, there is no way to use Apple's highest performance Mac Pro in a Windows environment. I think that's inconsiderate of Apple. I would like the performance of 15,000 rpm SCSI drives (RAID or not) but I also need Windows XP. I'm sure many others will face the same dilemma. Apple should give this matter a high priority and churn out the sorely needed drivers. So back to my original question--five Apple tech reps said I can configure the machine as described above and it will work fine--the sixth rep said there is no way it can work, because their card cannot run Windows. Who should I believe. I don't want to make a ten-thousand dollar mistake.
    P.S. The configuration shown below is for the machine I hope to purchase, not the one I'm using now. This one is a 3GHz Dual-Core Intel Xeon Mac Pro.

  • Mac Pro RAID Card - RAID 5 capacity with 4 drives

    Greetings everyone,
    last weekend, I installed a Mac Pro RAID card in my Mac Pro, gave it 4 Samsung 1TB disks to play with and set up a RAID 5 array on it. However, the capacity is less than what I would have expected (expected around 2.8TB and got 2.38TB).
    After some searching on the Apple Support pages, I found this ...
    http://docs.info.apple.com/article.html?artnum=306212
    ... support article stating that in a 4 column RAID 5, the capacity indeed could be less than expected due to "data placement and layout techiques".
    Does anyone know the technical reason behind this? Any other RAID 5 I know, hardware or otherwise, does not have this quirk.
    Is there any way to work around this? If not, are there any other, comparable RAID cards that get this right?
    Thanks in advance,
    -sai

    Hi sairath;
    With RAID 5 one of the drive is devoted to Parity so that the data can be restored in case of a drive failure. Hence you are only going to see the space for three of the drive so your results sound pretty normal.

  • Mac Pro & RAID Card configuration

    hello-
    i've got a 2 x 2.26 Quad Core Xeon Mac Pro with an Apple RAID card in it
    1 x 1TB system drive
    and
    3 x 2TB media drive for video
    question: can i have the system drive separate from the RAID card and just create a 6TB RAID0 array for the media drive?
    i've heard that the system drive should be part o the RAID (currently it's its own JBOD RAID, so NOT part of the 6TB array) but I can't see how to do this
    any help/advice will be much appreciated.
    thanks
    david

    If you have a RAID card installed and the drives are in their trays, they're all going through the RAID card (for MLB interface purposes). You could have a single drive setup as the sys drive and then the three drive RAID 0 set. The card will support RAIDed and non-RAIDed disks. I currently have a MacPro with a RAID card installed, yet all of the disks are setup with the original OS-based RAID configuration (will be switching soon as the RAID card was just installed). You have plenty of choices and what you're wanting to do is totally doable with or without the RAID card, as it could be done in the OS via Disk Utility.

  • Mac Pro + RAID Card = No Bootcamp?

    I have a Mac Pro with a RAID card in it and 4 drives connected to the RAID card. As is pointed out in the Bootcamp manual, the RAID card won't work since Windows does not have drivers for it.
    Being persistent, I figure I just add a 5th drive to the system. I did so using one of the ODD-Sata (Optical Dist Drive SATA) ports (the extra ports on the Motherboard), only to find out that Windows still does not see this drive.
    Now, there are supposed to be 6 SATA ports on the motherboard, right? But I cannot locate any of the other ports, I only see the 2 ODD-SATA ports. Does anybody know if it is possible to hook my 5th drive up to one of the other SATA ports and so still get Bootcamp working?

    I got the same cable from Newark. It was a bit of an adventure to get it installed, you need to take the plastic housing of the "fan assembly" out, which you can do after you remove the cover of the heat sink fans.... there is some info on the web on how to take apart your Mac Pro, just search for it.
    The result is GREAT! I got some Sata female to female connectors at Newegg, which allows me to attach a long Sata cable to the short stubs of the Molex 3009 cable (that I got from Newark). I also got a power cable converter, old style to sata power plug.
    After plugging in an empty Sata drive, copy your system onto that drive (or do a fresh install, whatever). Then you can boot from your new drive, not the RAID. Once you've done that, you can use bootcamp as it is supposed to work. Windows XP installed without a hitch. The partition with the copy of your main system is not a bad thing to have either, incase you mess up your main system. I don't think you could wipe it, since I think (but am not sure) that it is needed for booting. You could probably shrink it to something tiny if you like.
    So, problem solved! Now I have the possibility of hooking up 4 more drives....

  • Does a Mac Pro RAID card affect a Sil3132 PCI-E Card ?

    I've got a Mac Pro with the Apple RAID card (Slot4)
    I've put a Sil3132 PCI-E eSATA card into Slot 3.
    I can load drivers (v1.1.9 Silicon Image), and see the eSATA card in the System Profiler
    But I cannot get it to see the hard disks connected to the eSATA bus.
    The cables and disks work with my other Mac that has eSATA but not on the Mac Pro.

    I've got a Mac Pro with the Apple RAID card (Slot4), I've put a Sil3132 PCI-E eSATA card into Slot 3. I can load drivers (v1.1.9 Silicon Image), and see the eSATA card in the System Profiler.
    Hi,
    I have seen system conflicts occur when both the Apple RAID card and SI drivers were installed. It may also be another driver that is causing the issue. To troubleshoot this issue I would install a fresh copy of Mac OS X on a spare HD using the Apple DVD and boot from it. Next, install the SiI-3132 1.1.9 driver, reboot and see if the issue still exists.
    If the issue is resolved you will know something else is causing the problem on the regular boot disk.
    Another possibility is that the SiI-3132 card has the RAID BIOS flashed to the card. This will usually occur if the card is purchased from a PC vendor. In that case, the card may not work unless the Mac SiI 3132 32-bit universal SATARAID5 driver is installed OR the card is flashed back to BASE BIOS.
    You can find the drivers here:
    http://www.siliconimage.com/support/searchresults.aspx?pid=32&cat=3
    Unfortunately, there is no Mac driver uninstaller provided by Silicon image and the different driver versions install several files in different locations. This is why it pays to buy the SI controller from a Mac based reseller that knows what BIOS is installed. If you did not purchase from a good Mac reseller then it is best to test the card with a spare boot disk that you can erase if the wrong driver is installed. I would not want to mess up my main boot disk with these driver tests
    Have fun!

  • Mac Pro RAID 5 disk goes offline frequently in a random way. What can be causing this odd behavior?

    Hi dudes,
    I installed recently two Mac Pro RAID cards inside their corresponding Mac Pro systems. Four 2 TB Hitachi SATA disks are contained inside each system, and configured as RAID 5. Yes, the operating system is installed on this RAID 5 volume in order to get the highest performance of the array, taking advantage of the RAID 5 protection (Autodesk Smoke runs in each system; this application works only with uncompressed video in real time). I already had tested both systems keeping separated the boot disk just for the operating system, and making the RAID 5 volume just with three 2 TB disks, but the performance was slow on both systems.
    The performance is now very good, but unfortunately, in both systems happens that sometimes one of the disks goes offline with no apparent reason. The RAID Utility immediately reports the failure and it is mandatory to declare as spare the disk that went offline. Then the rebuild process begins, but in the meantime, the performance goes down in a noticeable way. Sometimes it is even worse, because the disk disappears completely. Then, it is mandatory to turn off the system, and boot it up again, in order to see in the RAID Utility the missing disk, which needs to be declared as spare in order to be reintegrated into the RAID 5 volume in a slow rebuilding process.
    Some important remarks: this very new Mac Pro systems do not have the iPass cable (at least apparently; I already disassembled completely one of these systems). This cable is mentioned in one Mac RAID card manual that I found over the internet. The diagrams do not match exactly with the Mac Pro nor the Mac Pro RAID board. I did not find a proper iPass connector in any of the Mac Pro RAID cards (?!). So, my guess is that currently the communication between the system and its Mac Pro RAID card is just by means of the internal bus. I think that if the iPass connection were mandatory, the RAID Utility would report it with a noticeable error message. Please advise.
    I think that these Mac Pro RAID cards need a firmware upgrade, in order to be able to work fine with big SATA drives. Again, please advise.
    Thanks in advance from Mexico.
    Sincerely,
    Martin Ponce de Leon

    Hi Grant,
    Thank you for your prompt response. The manual is a PDF document issued by Apple and it seems OK, but no updated to the latest Mac Pro system and Mac Pro RAID. I do not find the link where I found this manual. The systems belong to one of our customers. As far as I remember, in the printed manual included with the boards, it is not mentioned anything about the iPass cable, just about the battery cable. Do you know where can I get a PDF manual of the latest Mac Pro RAID card and the latest Mac Pro system? This client is far from our offices. So, I would prefer a PDF copy of this manual.
    The drives that have gone offline, once they are back, are reported in a good status in the RAID Utility. Besides that, I have tested them in another system in our facilites, and all of them work fine. So, my guess is that the high capacity drives are not yet supported by the Mac Pro RAID card, or it requires a firmware update.
    They do need to have in the same volume OS and video storage because three disks do no provide a good performance (they need also RAID 5), but four disks work fine... excepting when one disk is missing. Please advise. Thank you.
    Best Regards,
    Martin

  • Mac Pro RAID 0 setup with bootcamp

    I'm about to take the plunge and buy a Mac Pro as soon as I get the money (or credit) to. There have been things here and there that have turned me off but I found ways around some concerns, but this one I haven't been able to find.
    I am a musician and want to utilize raw power that Mac does so well with. But unfortunately my DAW of choice doesn't support OS X. I hate Vista, I never upgraded, I stayed with XP but have been willing to change to OS X with XP as well, to get the best of both worlds. Then i find my DAW doesn't support XP 64 bit so i am going to have to use Vista 64-bit (bummer).
    What I haven't been able to figure out is if it is possible to run a RAID 0 of the windows OS and all its data. The Mac Pro RAID card doesn't support any Windows OS so i am wondering if there is anyway possible to get the Windows OS in RAID, any good hardware or software that will accomplish this. Like if i get the Mac Pro RAID cad, is there a good software or hardware RAID that will allow me to install windows in a RAID 0 configuration?
    If its possible I would have no reasons to not move over, but I really need to have my RAID setup in windows since I am using latency sensitive disk streaming programs that need to stream files in the GBs
    Also could I just opt out for the Mac Pro Card and get a generic RAID card that supports both Windows and OS X? And if so any recommendations?

  • Graphics card crash on Mac Pro RAID

    I've had a very odd issue with a Mac Pro RAID running SL client.
    The Mac Pro serves files to a small network of Macs and is usually very reliable, however I was archiving and moving around a lot of files (over 100gb) overnight and when I returned next day, the monitor that the Mac pros connected to wouldn't show the desktop screen.
    The monitor had power, and the Mac was turned on, still serving files as normal and had not crashed in any way.
    I VNC'ed into this Mac and the desktop appeared, and looking in system profiler the video card wasn't there.
    A restart sorted it out.
    This has happened a few times and it's always when a large file copy is in progress overnight. The screen is switched off overnight by default.
    I've thought the graphics card (ATI Radeon HD 5870) maybe overheated, so I cleaned the inside of the Mac of dust (it was a bit dusty but not much), but the problem remains, always when a large file copy takes place.
    The past couple of times this has happened I couldn't even VNC into the Mac and had to restart it remotely using the terminal.
    I've seen this article from Apple, but the video card cables are connected as normal:

  • Mac Pro RAID Rechargeable Lithium Battery

    I am trying to purchase a replacement Apple Mac Pro RAID Rechargeable Lithium Battery for a Mac Pro tower. It is an oblong battery about 3"x2"x0.25" (8.0 cms x 5 cms x 0.5 cms).
    Mine no longer accepts a charge so the cache won't back up. The Mac Pro is less than 18 months old.
    I have tried the Apple online store, the Apple Store in Covent Garden, Albion (an Apple Premium Reseller on the Strand in London) and even CTS (an Apple Premium Reseller in Paris while there this weekend).
    No-one seems to know of it let alone stock it.
    Can anyone tell me where I can find it?
    I have to say Apple's support on this is useless.
    All help appreciated.
    Mike

    Is there an "official" policy regarding the way one should treat a machine with a raid card. Some say never to switch off the machine, others say this is nonsense, as even if the MacPro is switched off, the battery should still be able to maintain it's charge. I have heard various Apple representatives say different things, but as far as I recall, I have never seen something in writing. Besides, my Raid Card lasted exactly one week before it needed replacement. I have now been sent a battery replacement after 4 months, and it failed (again) while keeping the machine on...so I am really confused.
    Thanks in advance.

  • Mac Pro airport card boot issues

    I've taken an old airport card from a Mac Mini, and installed it in an Early 2009 Mac Pro.
    The unit should be fully compatible, but when I boot, it just hangs at the 50% mark on the startup screen.
    If I remove the card, the machine boots just fine.
    Is there a firmware update I need to make to the system, to tell it about the new wireless card?

    What makes yo think it is compatible? It seems not to be.
    Also these do not list a Mini card being compatible with a Mac Pro desktop card
