Do not proceed to the next step if any LUN is not in an optimal state and you
intend to move any of the disks which comprise the LUN. Contact HP Support
if the LUNs cannot be made OPTIMAL before the moving disk drives.
3. If you intend to move any global hot spares, remove them from the hot spare group as
follows:
a. Verify that the hot spare disk to be moved is not in use.
b. Remove the disk from the hot spare group.

AUTION
Use proper Electrostatic Discharge (ESD) procedures during the expansion
procedure. ESD discharges can easily damage the HP FC60 Array and drive
components. Wearing an ESD wrist strap grounded to the component chassis
is sufficient for most environments.
1. Power down the disk array components in the following order:
a. Switch off power to the controller enclosure. Make sure that both power supplies
have been turned off before proceeding.
b. Switch off power to each disk enclosure.
2. Remove the Fiber Channel cables connected to the controller enclosure.
3. Disconnect all SCSI cabling from the controller enclosure and the disk enclosures.
4. Install the new disk enclosures in the rack. See "Step 4: Install the Disk Enclosure" on
page 162 .
