Logical Drive Problems:
Logical drive Problems typically result from a physical drive failure. The most
common Problem is a critical logical drive. The RAID controller can rebuild a
critical logical drive.
A more serious but far less common Problem is an Incomplete Array. An
incomplete disk array results from a physical drive that fails or becomes
missing during:
−
RAID level migration
−
Physical drive transport
3.4.4 Spare Drive Management
If you have an unassigned disk drive, you can assign it as a spare drive. A
spare is a disk drive that has been designated to replace a failed disk drive in
a RAID Volume. In the event of the failure of a disk drive within a RAID 1 or
three drive RAID 5 Volume, the spare drive is activated as a member of the
RAID Volume to replace a disk drive that has failed.
A spare drive cannot replace the failed drive in a RAID 0 Volume because of
the way in which data is written to the disk drives under RAID 0. A spare drive
is not available for a RAID 10 Volume because RAID 10 requires all four disk
drives in the ShareCenter
®
Pro DNS-1550-04 enclosure. However, when you
replace the failed disk drive, the ShareCenter
®
Pro DNS-1550-04 will
automatically rebuild the RAID Volume using the new disk drive.
