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.
A virtual disk is in a degraded state
If the virtual disk is in a degraded state, check the following causes:
1.
.
2.
Physical or mechanical problems with the physical disk
3.
The virtual disk has lost redundancy
.
4.
Corrupted metadata in the virtual disk
.
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.
Check if the physical disk in the virtual disk has failed.
2.
If a physical disk was recently removed and replaced, check that it is correctly positioned in the backplane. Check the cable
connections at the physical disk and at the system board. Perform a
Rescan
.
The virtual disk has lost redundancy
1.
One or more physical disks in the virtual disk 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.
2.
Replace the physical disk or disks. Rebuild the physical disk using Storage Management. See the applicable
Storage
Management
screen at
dell.com/support/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
