Cause and
Action
Cause: Unrecoverable medium error found on one or more member physical disks
of a virtual disk.
Action: Perform a backup of the virtual disk with the Verify option selected. If the
Backup operation is successful, it indicates that the un-recoverable medium did
not affect user data.
If the Backup operation fails, restore the file from a previous backup. After restoring
the file, run check consistency operation:
• If the consistency check is successful, no further action is required.
• If the consistency check finds and unrecoverable medium error, it means that
the medium error is located in non-user data. No further action is required as,
writing data to the location of the medium error fixes the problem.
NOTE: If the unrecoverable medium error has not been corrected, it may be
reported again by the system. This error can be fixed by writing data on the
affected area or deleting and recreating the Virtual Disk as demonstrated in the
following procedure.
1. Back up the data.
2. Delete the Virtual Disk.
3. Recreate the Virtual Disk using the same parameters like size, RAID level,
disks, etc.
