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.
a. Press on the inside of the bottom of the tray handle to release the blue latch
1 .
b. Pull the handle 2 on the tray 3 out into the open position.
c. Lift the drive CRU 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 RAID storage controller 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 RAID storage controller.
f. If you are replacing a slim drive, ensure that the filler piece remains in place
for use with the new drive.
5. Install the new drive CRU.
a. Gently push the drive CRU into the empty bay until the tray handle 2
touches the storage-server bezel.
b. Push the tray handle 2 down into the closed (latched) position.
6. Check the drive LEDs.
a. When a drive is ready for use, the green Activity LED is on, and the amber
Drive fault LED is off.
b. If the amber Drive fault LED is on and not flashing, remove the drive from
the unit and wait 10 seconds; then, reinstall the drive.
7. Return to normal operation.
