- Getting help
A virtual disk is in a degraded state
If the virtual disk is in a degraded state, check the following causes:
1. A physical disk was removed.
2. Physical or mechanical problems with the physical disk.
3. The virtual disk has lost redundancy.
4. Corrupted metadata in the virtual disk.
Virtual disks are degraded on migrating the physical drives
Likely Cause: Rebuild in the new unit does not start automatically.
Corrective
Action:
Start the rebuild in the new unit through OpenManage.
A physical disk was removed
1. Install the original physical disk if it was inadvertently removed, or replace it with a new or used physical disk.
2. Initialize a new physical disk. Perform a Rescan for all physical disks that are replaced.
3. If the physical disk was not removed, check that its cables are correctly installed.
Physical or mechanical problems with the physical disk
1. Determine if the physical disk in the virtual disk has failed.
2. If a physical disk was recently removed and replaced, determine that it is correctly positioned in the backplane. Check the
cable connections at the physical disk and at the system board.
3. Perform a Rescan
The virtual disk has lost redundancy
One or more physical disks in the virtual disk may have failed, due to the failed physical disk or disks, the virtual disk is no longer
maintaining redundant (mirrored or parity) data. The failure of an additional physical disk results in lost data.
1. Replace the physical disk or disks.
2. Rebuild the physical disk using Storage Management. See the applicable Storage Management screen at www.dell.com/
manuals.
Corrupted metadata in the virtual disk
1. Delete the virtual disk that has the failed metadata.
2. Assign the physical disk as a hot spare to rebuild a redundant virtual disk.
3. To create a non-redundant virtual disk, delete and rebuilt the data on a virtual disk, and restore the data from a backup
storage source.
Cannot assign a dedicated hot spare to a virtual disk
If you cannot assign a dedicated hot spare to a virtual disk, check the following causes:
1. The RAID level does not allow a dedicated hot spare to be created.
2. The designated physical disk does not have sufficient capacity to be a dedicated hot spare.
3. The physical disk is already part of a virtual disk.
4. The physical disk are of different types.
