Replacing hot-swap hard disk 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 server. This
includes transmission problems between the host controllers, the RAID controllers,
and the drives. This section explains how to replace a failed hard disk drive.
Note: If you want to remove a hard disk drive that is not in a failed or bypass state,
always use the Storage Manager client program either to place the drive in a
failed state or to place the array that is associated with the drive (or drives)
in an offline state before you remove the drive from the enclosure.
Attention: Failure to replace the hard disk drives in their correct bays might result
in loss of data. If you are replacing a hard disk drive that is part of a configured
array and logical drive, ensure that you install the replacement hard disk drive in the
correct bay. Check the hardware and software documentation that is provided with
your FAStT storage server to see if there are restrictions regarding hard disk drive
configurations.
Complete the following steps to replace a hot-swap hard disk drive:
1. 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 Fault LED is on and not
flashing or when the drive is inactive with the green Activity LED on and not
flashing.
If the drive is not in a failed state (as indicated by its lit amber LED), manually
fail the drive using the Storage Management client before attempting to remove
it from the drive slot.
2. Remove the drive CRU:
a. Release the latch on the drive CRU by pinching together the blue line on the
tray latch and the finger hole on the tray handle, as shown by the arrow in
Figure 56 on page 71.
b. Pull the tray handle out into the open position.
c. Lift the drive CRU partially out of the bay.
d. To avoid possible damage to the drive, wait at least 20 seconds before fully
removing the drive CRU from the storage server to allow the drive to stop
(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.
3. Install the new drive CRU:
a. Gently push the drive CRU into the empty bay until the hinge of the tray
handle latches beneath the storage server bezel.
b. Push the tray handle down into the closed (latched) position.
4. Check the drive LEDs:
v
When a drive is ready for use, the green Activity LED is either on
continuously or rapidly flashing, and the amber Fault LED is off.
v
If the amber Fault LED lights and is not flashing, remove the drive from the
unit and wait 10 seconds; then, install the drive again.
