Smart error detected on a physical disk in a non-redundant virtual
disk
Issue: A SMART error is detected on a physical disk in a non-redundant virtual disk.
Corrective
Action:
Perform the following steps:
1. Back up your data.
2. Use Replace Member or set up a global hot spare to replace the disk automatically.
NOTE: For more information about the Replace Member feature, see the topic Configuring hot
spare.
3. Replace the affected physical disk with a new physical disk of equal or higher capacity.
4. Restore from the backup.

Source disk fails during replace member operation
Issue: The source disk fails during the Replace Member operation and the Replace Member operation stops
due to the source physical disk error.
Probable Cause: Physical disk failure or physical disk is removed or disconnected.
Corrective
Action:
No action required. If the virtual disk can tolerate disk failure, and the source data is available from other
disks in the virtual disk, the rebuild begins automatically on the target disk, using the data from the other
disks, if the virtual disk cannot tolerate the failure, the virtual disk goes to offline state and the replace
member operation is stopped.
Target disk fails during replace member operation
Issue:
The target disk failure reported during the Replace Member operation, and the Replace Member
operation stops.
Probable Cause: Physical disk failure or physical disk is removed or disconnected.
Corrective
Action:
It is recommended that you replace or check the target drive, and restart the Replace Member
operation or perform the operation on a different target drive.
A member disk failure is reported in the virtual disk which
undergoes replace member operation
Issue:
The source and the target drive which is part of Replace Member operation are online, while a different
drive which is a member of the virtual drive reports a failure.
Probable Cause: Physical disk failure or physical disk is removed or disconnected.
Corrective
Action:
A rebuild starts if there any hot-spares configured or you may replace the failed drive. The Replace
Member operation continues as far as the source virtual disk can tolerate the drive failure. If the source
virtual disk fails, the Replace Member is stopped, otherwise the virtual disk continues to be in degraded
state.
