IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User's Guide
Read all precautionary notes, kit instructions, and other information. Kit
instructions often contain the most current information regarding the drives
and their installation, plus upgrade or servicing procedures. Compare the kit
instructions with this procedure to determine if you need to modify this
procedure.
2. Use the Storage Manager client to check the status of the storage server.
Correct any problems that are reported.
3. Perform a complete backup of the drives that you are replacing.
You need the backup to restore data on the drives later in this procedure.
Attention:
When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see "Handling static-sensitive devices" on page 57.
4. Unpack the new drives.
Set the drives on a dry, level surface away from magnetic fields. Save the
packing material and documentation in case you need to return the drives.
5. Perform the following steps:
a. Stop all I/O activity to the storage server and attached expansion units.
Make sure that:
1) All of the green Drive activity LEDs on the front of the storage server
(and on all attached expansion units) are not flashing.
2) The green Cache active LEDs are off on the front of the RAID
controllers.
b. If applicable, use the operating system software to disconnect the storage
server logical drives from the host before you power off the storage server.
Attention:
To turn off all power to the storage server, you must turn off both
power-supply switches and disconnect both power cords. Use the procedure in
step 6 for the proper shutdown sequence.
6. Turn off the power to each device based on the following shutdown sequence:
a. Turn off power to the host before you turn off power to the storage server.
If the host must stay powered on to support an existing network, see the
operating system documentation for information about disconnecting the
storage server logical drives from the host before the storage server is
powered off.
b. Turn off power to the storage server before you turn off power to the
expansion units. Turn off both power supply switches on the back of the
storage server.
c. Turn off power to other supporting devices (for example, management
stations, fibre-channel switches, or Ethernet switches).
Notes:
1) You do not need to perform this step if you are servicing only the
storage server.
2) Depending on your operating system, you might not have to restart the
host. For more information, see the software installation guide for your
operating system.
7. Use the procedures in "Replacing hot-swap drives" on page 75 to remove the
drives that you want to replace. Use the procedures in "Installing hot-swap
drives" on page 73 to install the new drives into the storage server.
8. After you install all the new drives, check the system documentation for the
hardware devices that you intend to power up, and then determine the proper
startup sequence. Use the following power-on sequence, where applicable:
