6. Check the drive LEDs.

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 storage 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:
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 replace a hot-swap drive:
1. Determine the location of the drive that you want to remove.
2. Remove the drive CRU.

c. Slide the drive CRU into the empty bay until the tray handle 2 touches the
expansion-unit bezel.
d. Push the tray handle 2 down into the closed (latched) position.
a. When a drive is ready for use, the green activity LED and the amber fault
LED are off.
b. If the amber fault LED is on, remove the drive from the unit and wait 10
seconds; then, reinstall the drive.
ServeRAID information In some cases, the ServeRAID controller will automatically reset the
drive to the Hot Spare or Rebuild state. If the drive state change does not occur automatically
(amber LED stays lit), refer to your ServeRAID documentation for information about manually
changing the state of the drive from the current state to another state, such as Hot Spare or
Ready. The amber LED should switch off within 10 seconds after the drive-state change.
Failure to replace the drives in their correct bays might result in loss
Attention:
Never hot swap a drive CRU when its green activity LED is
flashing. Hot swap a drive CRU only when its amber fault LED is lit (not
flashing) or when the drive is inactive (activity LED is off).
a. Press on the inside of the bottom of the tray handle 2 to release the blue
latch 1 .
b. Pull the handle 2 on the tray 3 out into the open position.
c. Lift the drive tray partially out of the bay.
d. To avoid possible damage to the drive 4 , wait at least 20 seconds before
fully removing the drive CRU from the storage unit, 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 unit.
