documentation that is included with the new drive to find out the minimum
controller and ESM firmware versions, or any prerequisite tasks, for DS4000
controller and EXP100 ESM.
4. 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 30.
5. Put on the antistatic strap and 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.
6. Perform the following steps:
a. Stop all I/O activity to the DS4000 storage subsystem and attached
expansion enclosures. Make sure that:
1) All of the green Drive activity LEDs on the front of the DS4000 storage
subsystem (and on all attached EXP100s) are not flashing.
2) The green Cache active LEDs are off. Depending on the model, the
cache active LEDs are either in the front (DS4500) or the back
(DS4300) of the storage subsystem.
b. If applicable, use the operating system software to disconnect the DS4000
storage subsystem logical drives from the host before you power off the
storage subsystem.
Attention: To turn off all power to the DS4000 storage subsystem, you must
turn off both power-supply switches and disconnect both power cords. Use the
procedure in step 7 for the proper shutdown sequence.
7. 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 DS4000 storage
subsystem. If the host must stay powered on to support an existing
network, see the operating system documentation for information about
disconnecting the DS4000 storage subsystem logical drives from the host
before the storage subsystem is powered off.
b. Turn off power to the DS4000 storage subsystem before you turn off power
to the EXP100. Turn off both power supply switches on the back of the
DS4000 storage subsystem.
c. Turn off power to other supporting devices (for example, management
stations, Fibre Channel switches, or Ethernet switches).
8. Use the procedures in “Replacing hot-swap hard disk drives” on page 76 to
remove the drives that you want to replace. Use the procedures in “Installing
hot-swap hard disk drives” on page 74 to install the new drives into the
EXP100.
9. 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:
a. Turn on the power to the supporting devices (for example, Ethernet
switches and management stations) before you turn off power to the
DS4000 storage subsystem.
b. You must turn on the expansion enclosures before the DS4000 storage
subsystem. The controllers might not recognize the correct configuration if
