The Dell S100/S300/S110 RAID controller states a hard drive is still a hot spare after rebuilding into an array

The Dell S100/S300/S110 RAID controller stating that a hard drive is still a hot spare after rebuilding array

After configuring a hard drive as a Hot Spare on an S100/S300/S110 RAID controller that hard drive will begin automatically rebuilding a failed drive in a degraded array.  The following conditions must exist:

• The Hot Spare drive has enough space to rebuild the missing member
• The array must be in a degraded state
• No other members of the Virtual Disk have been rebuilt to the Hot Spare

When the rebuild is complete the drive continues to report that it is a hot spare. This is seen both in the OpenManage by looking at the physical disks or within the controller itself.

The issue is the hard drive continues to state it is a hot spare after rebuilding into the array.  This behavior is normal and by design.  The purpose of this feature is to allow a single drive to be a Hot Spare for multiple arrays.  Only 1 drive per array can rebuild to the Hot Spare.
