Dell PowerEdge RAID Controller S110 - Manual (Page 52)

50 Troubleshooting
A Dedicated Hot Spare Fails
The controller cannot communicate with the hot spare
• Check that the cable from the controller to the physical disk is connected
properly.
• Make sure that the physical disk is still assigned as a global or dedicated
hot spare.
• Check if the physical disk assigned as the hot spare has failed.
The dedicated spare is not visible in the PERC BIOS Configuration Utility or
is offline.
The Wrong Physical Disk was Removed
A physical disk has been removed from a virtual disk
The removal of one physical disk from a virtual disk causes:
• A Volume or RAID 0 virtual disk to change to Failed status.
• A RAID 1 and RAID 5 virtual disk to change to
Degraded status.
• A RAID 10 virtual disk to change to Degraded status (when a physical disk
is removed from one of the mirrored sets).
Re-insert the removed physical disk and perform a Rescan of the virtual disk.
