To investigate the cause, check for the following:
● Whether the virtual disk is in Degraded status because one of the physical disks of a RAID 1 or RAID 5 virtual disk has failed,
or one of the physical disks of a RAID 10 virtual disk has failed. Press Ctrl+R and verify if the physical disks are offline or
missing. Remove and replace a failed physical disk. A second physical disk failure could cause a Degraded virtual disk to

the physical disks are offline or missing. Remove and replace the failed physical disk or disks.
