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. This includes transmission
problems between the host controllers, the RAID controllers, 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.
Use the following procedure to replace host-swap drives.
1. Check the hardware and software documentation that is provided with the system
to see if there are restrictions regarding hard disk drive configurations. Some
system Fibre Channel configurations might not allow mixing different drive
capacities or types within an array.
2. Check the storage-management software for recovery procedures for a drive that
has failed. Follow the steps in the software procedure before continuing with this
procedure.
3. Determine the location of the drive that you want to remove.
Attention: Never hot-swap a drive CRU when its green Activity LED is flashing.
Hot-swap a drive CRU only when its amber Drive fault LED is on and not flashing
or when the drive is inactive with the green Activity LED on and not flashing.
4. Remove the drive CRU.

, wait at least 20 seconds before
fully removing the drive CRU from the storage server to allow for the drive 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 storage server.
f. If you are replacing a slim drive, ensure that the filler piece remains in place
for use with the new drive.
