Offline or missing virtual drives with preserved cache error message
Error Message:
There are offline or missing virtual drives with preserved
cache. Please check the cables and ensure that all drives are
present. Press any key to enter the configuration utility.
Probable
Cause:
The controller preserves the dirty cache from a virtual disk if the disk becomes
offline or is deleted because of missing physical disks. This preserved dirty cache is
called pinned cache, and is preserved until you import the virtual disk, or discard
the cache.
Corrective
Action:
Use the <Ctrl> <R> utility to import the virtual disk or discard the preserved cache.
For the steps used to manage preserved cache, see Managing The Preserved
Cache .

Probable
Cause:
This message is displayed when the BIOS detects virtual disks in a degraded state.
Corrective

Take corrective action(s) to make the virtual disks optimal. The BIOS does not take
any action.
Virtual disks degraded error message
Error Message:

Ensure all disks in the Virtual Disk are present and online.
Replace any failed disks that may be in the array.
Correct a hot spare disk, and rebuild the array.
The BIOS does not take any action.
Virtual disks partially degraded error message

virtual disks partially degraded.
Probable
Cause:
