Attention:
1. 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 completely on and not flashing or
when the drive is inactive with the green Activity LED on and not flashing.
2. After you remove a drive CRU, wait 70 seconds before replacing or reseating
the drive CRU to allow the drive to properly spin down. Failure to do so may
cause undesired events.
Before you install or remove drive CRUs, review the following information:
Filler panels
Storage subsystems without a full set of drives (14) contain filler panels in
the unused drive bays. Before installing new drives, you must remove the
filler panels. Save the filler panels for future use. Each of the 14 bays must
always contain either a filler panel or a drive CRU.
Drive CRUs
The RAID controller supports up to 14 (half-high or slim) 40-pin
fibre-channel hard disk drives. These drives come preinstalled in drive trays.
This drive-and-tray assembly is called a drive CRU . You can install the drive
CRUs in the 14 drive bays on the front of the storage subsystem.
Drive LEDs
Each drive CRU has two LEDs, which indicate the status for that particular
drive. For information about the drive LED operating states and
descriptions, see Figure 73 on page 98 and Table 13 on page 98.
Fibre-channel loop IDs
When you install a drive CRU in the storage subsystem, the drive CRU
connects into a printed circuit board called the midplane . The midplane
automatically sets the fibre-channel loop ID to the default value 00.
Hot-swap hardware
The storage subsystem contains hardware that you can use to replace a
failed hard disk drive without turning off the storage subsystem. Therefore,
you can continue operating the system while a hard disk drive is removed
or installed. These drives are known as hot-swap drives.
Slim drives
You can install slim, hot-swap drive CRUs.
Installing hot-swap drives
Before you begin: Take the following precautions.
v Read the safety and handling guidelines that are provided in “Safety” on page iii
and “Handling static-sensitive devices” on page 105.
v
Ensure that the current system configuration is working properly.
v Back up all important data before you make changes to storage devices, such as
hard disk drives.
Use the following procedure to install hot-swap drives in the storage subsystem.
You can install additional drives while the storage subsystem is powered up and
running.
Note: If you are replacing a drive, see “Replacing hot-swap drives” on page 123.
1. Read the instructions that come with the drive CRU.
2. Check for Fault LEDs. If any amber LEDs are lit, see “Checking the LEDs” on
page 97 and “Troubleshooting” on page 145.
