Replacing HSG60 and HSG80 controllers

in single-controller configurations

Use the steps in “Removing a controller” below and “Installing

a controller” on page 4 to replace a controller in a

single-controller configuration.

Caution: Static electricity can easily damage an array

controller. Wear a snug-fitting, grounded ESD wrist strap.

Removing a controller

Perform the following steps to remove a controller in a

single-controller configuration:

1. Connect a PC or terminal to the controller maintenance port

(see Figure 4) if the controller is operational. If the

controller is not operational, proceed to step 7.

Figure 4: Connecting PC and terminal cables to the controller

maintenance port (dual-redundant configuration shown)

2. From the host console, halt all host activity to the

controller, and dismount the logical units in the subsystem.

3. If you are using Microsoft

® Windows® NT® or Windows

2000, shut down the server.

4. Run the Fault Management Utility (FMU) to obtain the last

failure codes, if necessary.

5. Determine whether the disk was initialized with the

SAVE_CONFIGURATION switch, and then perform one of

the following options:

■ If the disk was not initialized with the

SAVE_CONFIGURATION switch, locate existing

information that will support the manual configuration

of the subsystem, and then proceed to step 6.

■ If the disk was initialized with the

SAVE_CONFIGURATION switch, enter the following

Command Line Interpreter (CLI) command from the

controller prompt to save the current device

configuration (for “this controller”):

CONFIGURATION SAVE

6. Shut down “this controller” with the following command:

SHUTDOWN THIS_CONTROLLER

Note: After the controller shuts down, the Reset button and the first

three LEDs turn on (see Figure 5). This can take several minutes to

occur, depending on the amount of data that needs to be flushed

from the cache module. Proceed only after the Reset button stops

flashing and remains on.

Caution: The cache module may contain unwritten data if

the controller crashes and it is not shut down with the

SHUTDOWN THIS_CONTROLLER command. Loss of data

can occur.

7. Remove the program card ESD cover (see Figure 6) and the

program card, and then save them in an antistatic bag or on

a grounded antistatic mat for the replacement controller.
