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 19.
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 have to return the drives.
5. Complete the following steps:
a. Stop all I/O activity to the storage subsystem and attached storage
expansion enclosures.
b. Make sure that all of the green drive activity LEDs on the front of the
storage subsystem (and on all attached storage expansion enclosures) are
not flashing.
c. Make sure that the green cache active LEDs are off. See “Controller LEDs”
on page 53 for the location of the cache active LEDs.
d. If applicable, use the operating-system software to disconnect the storage
subsystem logical drives from the host before you power-off the storage
subsystem.
Attention: To turn off all power to the storage subsystem, you must turn off
both power-supply switches and disconnect both power cords. Use the
procedure in step 6 for the correct shutdown sequence.
6. Turn off the power to each device according to the following shutdown
sequence:
a. Turn off power to the host before you turn off power to the storage
subsystem. If the host must stay powered-on to support a network, see the
operating-system documentation for information about disconnecting the
storage subsystem logical drives from the host before the storage
subsystem is powered-off.
b. Turn off power to the storage subsystem before you turn off power to the
storage expansion enclosures. Turn off both power-supply switches on the
rear of the storage subsystem.
c. Turn off power to other supporting devices (for example, management
stations or Ethernet switches).
7. Use the procedures in “Replacing a hot-swap hard disk drive” on page 75 to
remove the drives that you want to replace. Use the procedures in “Installing a
hard disk drive” on page 75 to install the new drives in the storage subsystem.
8. After you install all the new drives, check the system documentation for the
hardware devices that you intend to power-on, and then determine the correct
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
storage subsystem.
b. Turn on the storage expansion enclosures before the storage subsystem.
The controllers might not recognize the correct configuration if the drives
are powered-on after the storage subsystem. For instructions for
powering-on the storage subsystem, see the storage subsystem
documentation.
c. Turn on the power to the storage subsystem; then, restart or turn on the
power to the host.
9. Turn on the power to each device, according to the power-on sequence in step
8. To turn on power to the storage subsystem and the storage expansion
