2. A cable might be loose or defective.
3. The physical disk might be a SAS drive.
Re-seat the physical disks in the backplane and check their cables.
Insufficient free space available on the selected physical disks
There must be sufficient available free space on the physical disk used by the virtual disk.
Incorrect number of physical disks selected for the desired RAID level
For details about RAID levels and the allowable number of physical disks used with each RAID level, see understanding RAID
levels in RAID Technology Guide at dell.com/support/manuals.
The desired physical disk is unavailable
Determine whether the physical disk:
1. Is a dedicated hot spare and unavailable for use in another virtual disk.
2. Is full or has insufficient available capacity.
The system already has a maximum of eight virtual disks
Delete unused virtual disks.
CAUTION: Deleting a virtual disk destroys all data on the virtual disk.
A virtual disk is in a failed state
If the virtual disk is in a failed state, check the following causes in the listed order:
1. The virtual disk has lost one or more physical disks.
2. A physical disk in the virtual disk has failed or has been removed.
3. The virtual disk has lost the maximum allowable physical disks per RAID level.
The virtual disk has lost one or more physical disks
Replace the failed physical disk(s) and restore the data from a backup storage source.
A physical disk in the virtual disk has failed or has been removed
1. Re-install the original physical disk if it was inadvertently removed. Perform a Rescan.
2. Check the status of the physical disks in the virtual disk. Replace any failed disk(s), if necessary. Restore the data from a
backup storage source.
After any change, perform a rescan to verify if the disk is still in a Failed state.
The virtual disk has lost the maximum allowable physical disks per RAID level
One or more physical disks have failed:
1. If the virtual disk is non-redundant, the failure of a single physical disk can cause the virtual disk to fail.
2. If the virtual disk is redundant, two or more physical disks have failed and the virtual disk cannot be rebuilt.
Create a new virtual disk. Restore the data from a backup storage source.
