Virtual Disk error on Dell Powervault 220S

Posted on 2009-02-24

I have a Dell PE2650 connected to a Dell Powervault 220S.  I have (2) virtual disk's created on seperate RAID 5 arrays on the PV220.  After restarting the server for OS patch deployment the virtual disks are not seen by the OS.  

When I open Dell Server Manager and view "Storage" there is a red X by each of the Virtual Disks.  The only options available to me are "Delete", "Blink", and "Unblink".

How can I make these virtual disks available to the OS again without loosing data?

    Is the configuration a hardware RAID or a software RAID?

    The configuration is a hardware RAID.

    Try opening up the actual RAID configuration tool. I believe it will be CTRL-R as you are booting. Let us know what it says for the volumes.

    Are you getting any fault lights on the 220S? Are you getting a blink pattern on the drive lights?

    The drive lights where all amber in color with no blink pattern present.  The problem is now fixed.  Here is the probable cause and accepted solution.

    When I powered off the Powervault, the onboard Perc 4/DI controller put all the drives in a "failed" state even though nothing was wrong with them.  

    I was able to view the Powervault and drives in Dell's Open Manage console.  After reviewing a DSET report and controller report to verify there where no drive errors or virtual disk errors I was albe to bring the drives online.  I have 8 physical disks and I brought 7 of them online using the Open Manage console.  I choose the "rebuild" options for the 8th.

    I was then able to view the virtual disk as "Degraded" from the console.  My next step was to re-initialize the virtual disk from Windows Disk Manager.  As soon as I completed this my drive letter was mounted and all data was accessible.

    I hope this can help someone in the future.  

    Lessons learned:
    --Power down your Powervault only AFTER the physical server is attached is powered off.  
    --Investigate past drive failures before you force a drive online.  For example if I had a drive warning on 0:2 I would have brought all online except 0:2 and choose to rebuild that one.
