Replacing hot-swap drives

Drive problems include any malfunctions that delay, interrupt, or prevent successful
I/O activity between the hosts and the hard disk drives in the expansion unit. This
includes transmission problems between the host controllers, the ESM boards, and the
drives. This section explains how to replace a failed drive.
Attention: Failure to replace the drives in their correct bays might result in loss of
data. If you are replacing a drive that is part of a RAID level 1 or RAID level 5 logical
drive, ensure that you install the replacement drive in the correct bay.
Check the hardware and software documentation provided with your system to see if
there are restrictions regarding hard disk drive configurations. Some system SCSI
configurations might not allow mixing different drive capacities or types within an
array.

to spin down.
e. Verify that there is proper identification (such as a label) on the drive CRU,
and then slide it completely out of the expansion unit.
