Raid Utility wont Initialize a volume

Hi.
My Raid Utility won't initialize last two volumes. I have 3 tasks, 2 volume initialize tasks are Suspended, after that there is one Rebuild task that has a Scheduled status (the loading bar, no status bar). I did some digging and cleared all the events in the Controller status list. Both volumes are working, but won't initialize ? I tried rebooting, i got few more events that raid card started the rebuild process, then aborted it, then started it again, then aborted, and then started again. General status is Raid is rebuilding, but still I am not seeing the real status bar, like i saw last time. Is it really doing something or jammed?
It looks like the 2 suspended tasks would be preventing the rebuild to start, but the event log says it has started. Will the volumes initialize properly after the rebuild or do I need to get them to initialize them somehow before the rebuild can start?

Usually the drives have to be formatted separately as well as partitioned separately.
However, I don't quite understand what you are doing. You currently have four 500 GB drives configured as a RAID 0+1 which I would understand to mean two 500 GB drives striped, a second pair striped. That is two 1 TB striped arrays that are then combined into a mirrored array which would be 1TB. Now as I understand you want to resize one 500 GB drive that is already in the array. This I don't get.

  • Volume initializing in RAID Utility

    One of our Xserves was hung up today so I forced it off and restarted. The system has a RAID card and two 80GB drives mirrored. When the computer turned back on it flashed the folder question mark icon, it couldn't find a startup disk. Meanwhile the blue lights on the two drives were flashing. I inserted the OS DVD and it booted from that. Disk utility doesn't see the boot volume. RAID utility shows green lights for the two drives, but a yellow light for the volume and is currently Initializing.
    Did I just lose my boot volume? Or is RAID Utility rebuilding the volume and it will come back as before (please)?

    Twitter user @atunnell suggested
    Try putting it into a USB to SATA dock or adaptor and seeing if you can see it that way, RAID card itself may be the issue.
    I did that and the drive still contained the original boot volume. That was good news.
    So @atunnell suggested
    I would use carbon clone to make a back up and then wipe the main disks and try a re initialize If that works then restore the image
    I did that and it worked!
    So I'm all set for now. Thank you @atunnell !

  • I replaced the battery on my RAID card, when I booted my mac pro up, I get the folder with the question mark. I used a boot USB drive to boot and when I looked in the RAID utility, my RAID 5 volumes were no longer showing, advise.

    Not sure if I'm following you. I have 4 hard drives installed on my Mac Pro. I had a RAID 5 configured and functional for about 5 months. My battery died on the RAID card. I replaced the battery, seated the RAID card back in the slot I removed it from. When I booted to the USB drive to look in the RAID utility, I could see the battery is charged but my volumes are not showing.
    The drives don't show in disk Utility. I built the RAID with the RAID Utility and they did show there. I have a early 2008 Mac Pro, Mavricks OS running Mac Server

  • RAID Utility - Resize Volume?

    Hi,
    I've got a Mac Pro with a hardware RAID0+1, 4 x 500GB disks giving me a maximum of 1TB (ish) of storage.
    Thing is, the last 500GB disk was an addition and now I want to resize the original 500GB volume to use the full 1TB of storage offered by the array. I can't see an easy way to do it in RAID utility. Is it me or is this something that can't be done?
    Cheers,
    Stu

  • Intel Mac Tower / RAID Utility question

    I have a new Intel Mac tower with three 500 gb hard drives and a RAID card inside. I am attempting to create a RAID5 with 2 partitions (one 60 gb for os and other programs, and another partition with just under 900 gb for file sharing) - Trying to install mac osx tiger server (10 Client version) on my 60gb partition. I was able to do the following: boot machine from Client Install CD that came with the tower(as far as I know the tiger server os disk that I purchased does not have a RAID utility on it), used the RAID utility to create a RAID5, used the RAID utility to create the 2 partitions. Everything appears to work just fine after the RAID builds and partitions are created on them. Now if I either attempt to boot from the install disk for either mac os x server, OR from mac os x client os, I get to the point where you choose the partition (or volume) to install the os on, and I see NO VOLUME in the window below. Am I doing something wrong? If I need to give more detail please let me know.
    Thanks for any help in advance!

    Hi there ... i think i see what your issue is about.
    1) You bought a new MacPro CTO with the Raid card and want to turn your internal into a Raid 5 install.
    2) The raid card is again spanking brand new hardware in the machine and the actual support for the card does not come before 10.5 Server which is still on the way but you can certainly circumvent the issue with using a external drive install 10.4.x on the external and clone the external to your internal raid 5 to use as your boot drive.
    3) Make certain your partition on your 10.4 install is GUID on your raid. This is found in the Disk Utility options under the partition tab.
    4) Make sure your Mac os X server install DVD is 10.4.x Universal .. Do not use a 10.4 Server for PPC on a MacPro you ll meet 20 tons of worries . I would as well run the updates on the external drive first so when you clone you are up to 10.4.10 with all appropriate updates and utilities . As a safety measure installing your AppleRaid Card utility on the external drive would be a wise move so if they are updates to the utility they shall be taken into account.
    For a good clonning utility look for carbon copy cloner . it is not one of the fastest cloners out there but it is ROCK solid and fully supports 10.4.x server and a life saver as well.

  • RAID Utility & RAID Card

    I have my new super-duper Mac Pro tower 3.2 GHz with RAID card and I installed 4 identical 1 TB drives and made a RAID 5 array. Now, the issue is that I have had two power outages, and my UPS seems to have missed picking them up (I have a new UPS now for the tower), but here is the deal, I get the bad event, clear the event log, "initialize" the array (~1 day), Verify the array (~3 days) and RAID Utility can still give me the message that the array is "bad".
    So, I have, in sequence, a failure, a rebuild, a verify, a reboot (clean) and it goes back and complains it needs to rebuild from scratch even though it already has done so ...
    Also, clearing the errors does not seem to clear the errors from the log ...
    So, is it me ... or does the RAID Utility stink?

    FeistMeister wrote:
    Um, that was the point.
    I did a rebuild between the crash and the next one, and a verify ...
    I missed that.
    And after the second crash I did a complete initialize and verify with clean bill of health and all green dots....
    Now I am 3-4% into the initialize which will take until tomorrow sometime to finish ... then I can reverify ... but the point is that it does not seem to want to forget the past ... and "clearing" the log does not seem to make it forget the past either ...
    Well, it still boots off the array, and seems to run fine so I suppose I should not be TOO annoyed, but I expected better from Apple ... and better speed off of a dedicated $800 RAID card ... Oh, and the battery is fully charged ....
    I have never used RAID, probably because I never needed, but also I have read here and there of the requisite maintenance needed, and of problems similar to yours.
    I wish you well.

  • Raid utility

    My new Mac Pro with OSX Snow Leopard Server arrived a few weeks ago and since then I am trying to configure teh RAID (5) Set via RAID Utility but it keeps freezing on final percentage of the blue bar - Initializing... I tryed to reboot several times, also to delete the RAID Set or the Volume but still get no answer or evolution in the process. Any suggestions?

    Although Apple advertises the RAID utility as a way to turn multiple disks into a single RAID without data loss, you cannot consolidate or expand the capacity of an existing volume.
    My guess as to what happened on my machine is that the RAID utility miscalculated the available space in the RAID set and failed to automatically create my new, second volume.
    So you have a choice: either make a second volume out of the remaining space in your RAID set or else delete the volume, create a new volume with all remaining space and either reinstall or restore from backup. Since setting up the RAID was the first thing I did after opening the box, I chose to just reinstall the OS. I don't see the benefit in having multiple volumes if they are all from the same RAID set.
    In either case with RAID5 you're only going to have 2.5-3TB from four 1TB drives due to the parity data. I got a single 730GB volume from four 300GB drives, but it's worth it to me to get the increased stability of RAID5 over simple striping (since four drives are four times as likely to have a failure than a single drive by itself).

  • Raid Utility not an option on Lion Recovery Disk

    I am trying to delete a single RAID set that includes the startup volume.  I booted up with the Lion Recovery disk but only the disk utility is available as an option to erase information and no RAID utility is there.  I erased the startup volume and am re-installing.  If this doesn't fix the system so that I can try recreating the RAID set, does anyone have suggestions how to get back to the original four 2TB drives?
    Thanks, Alison

    To refine what the Hatter is saying...
    1) take an external drive. (USB is really slow, but can be used in a pinch. Firewire interface is much faster, and worth the price difference. It should be a 3.5" drive, and have its own power supply.)
    2) Install Mac OS X on the External drive.
    3) Boot from the External drive. Now you have the full capabilities of Mac OS X to act on everything else in your Mac.
    The Hatter often proposes that:
    ... rather than using a Utilities/Installer DVD or Recovery_HD to Install Mac OS X on an External drive from scratch, you can do just as good a job (and get a "free" bootable backup in the process) by:
    2alt) Cloning from an existing Mac OS X drive to that same External drive.
    [I am not sure you have that option at the moment, but it may be available when your system is stable again.]

  • 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.

  • FastBuild RAID setup wont allow me to create array (grayed-out) HELP!

    880GM-E41
    amd x4 970
    2x WD Raptor 74GB
     When I go into the FastBuild RAID menu, everything is grayed out. My drives show up, but they cant be select.  These drives were formated.  I tried to format again, but the Win 7 setup wont allow me to do it again (grayed-out).
    in the "view drive assignments" menu, my two drives say "<single disk>" under "assignment".  In the manual it acts like it should say, "free".
    in the "define LD" menu the drives show up as well, but everything is grayed-out.  Under "assignment" it says, "N" and I cant change it to "Y".
    These drives used to be set up as a RAID on my old system and Im really stumped as what to do to make it work.
    Thanks,

    The two disks are the WD740GD-00FLC0 and the WD740GD-00FLA1. (both SATA I) I had them in RAID before with my 6 year old Mobo and win XP.  
    The RAID utility doesn't register it as an array in FastBuild under option 2 or 3.  It shows up before the splash screen on startup when RAID does it diagnostic check  showing my two drives saying they're healthy.  The problem is it just wont let me select them in FastBuild (it shows them, but grayed out)
    Clearing CMOS didn't help.  I may try to download and flash the BIOS??
    This is all  very frustrating as my old system had this up and running...  but thanks for the help and any future help!
    Update: I went ahead and installed windows on one the the drives so I can use the PC, but Im still wanting to put them in RAID, Id hate to reformat and everything to find out it still doesnt work...

  • Raid Utility Error Message "raid utility is not supported on this computer"

    I am not doing anything that I know of, but Raid Utility keeps opening up on its own, and a message pops up multiple times a day telling me "raid utility is not supported on this computer"
    Anyone have any idea how to fix this?

    Network startup is if you want to start your macbook using a network drive.
    Keep your startup settings at your current drive.
    Raid utility doesn't apply to you since you only have one hard drive installed, unless you installed another hard drive in your optical bay.
    Fibre Channel is another type of hard drive connection via network connection.
    You can't access things you don't have installed in your macbook.  Those are there in case you decide to have a network drive start up options, a raid configuration of a fibre channel network drive.

    Otherwise software may be attempted to access the drive. The the computer up in Safe Mode by holding shift when you turn it on. Also be sure to power off and on the hard drive itself.

  • RAID Utility does not work after Vista upgrade

    Hi,
    I have a Qosmio G30 with 2 HD 120GB each. After I upgraded to Windows Vista from Windows XP, the Toshiba RAID Utility does not work anymore. In WXp it worked OK, but in Vista there is no way I can mirror the HD. That is, the utility itself work, but the button that should say Mirror, or something like that is not shown. I have set the drives to RAID-1 in the BIOS, but no go.
    Is there any way to get the software RAID to work again?

    Hi,
    just a little question: While installing vista, did you installed the RAID-driver at installation time? Maybe this could be the reason why RAID cannot be activated properly.
    Please give some feedback, if you installed the RAID drivers for Vista during the installation..
    Cheers

  • RAID Utility software not available in OS X Mavericks?

    Up till yesterday I have been using a RAID card in my Mac Pro (Mid 2010, 4 x 1 TB SATA, initially as RAID-5, now in a RAID-10 setup) under OS X 10.8.5 without any issues, and the RAID utility allowed me to check the status od me disks, event log, and the battery status / refresh cycles for the RAID card. Last night now I upgraded to OS X Mavericks. The upgrade went well, things appear to work OK, obviously at least half of my RAID-10 array is in use — however, I can't find the RAID utility, check the status of the RAID-10 system and the battery status of the RAID card. The disk utility shows the RAID set - but none of the underlying features (individual disks and their status, logs, battery) — am I thrown back to a soft RAID, and my investment into a RAID card has evaporated?

    Thanks a lot, Seliqui! the reason why I did not find it is that a) after the upgrade to Mavericks, the icon that I previously had parked in the dock no longer worked, and b) the new location for the utility can't be found anywhere on the Launchpad. I suspect both effects are an indication that they missed to add the new directory to the command path. I can hardly imagine that this was deliberate because if you have a RAID card you definitely want to have access to that utility — not just in case of a disk failure (I have had a couple of these!), but also in order to stop the user from doing things one is not supposed to do while the battery is reconditioning.
