Replacing cache modules in single-controller configurations
Complete the steps in the following subsections to replace HSG60 and HSG80
cache modules in single-controller configurations.
Caution: ESD can easily damage the cache module or a DIMM. Wear a
snug-fitting, grounded ESD wrist strap when completing controller cache
module removal and installation procedures.
Removing cache modules from single-controller configurations
Perform the following steps to remove a cache module in a single-controller
configuration:
1. Determine whether the controller is operational, and then complete one of the
following two options:
■ If the controller is operational, connect a PC or terminal to the controller
maintenance port, and then proceed to step 2.
■ If the controller is not operational, proceed to step 7 on page 135.
2. From the host console, stop all host activity to the controller, and then
dismount the logical units in the subsystem.
3. If you are using Microsoft Windows 2000 or Windows NT, shut down the
server.
4. Run the FMU to obtain the last failure codes, if necessary.
5. Shut down “this controller” by entering the following command:
SHUTDOWN THIS_CONTROLLER
6. Proceed to the next step only after the Reset button stops flashing and remains
on.
Note: After the controller shuts down, the Reset button and the first three port LEDs
light up. This can take several minutes, depending on the amount of data that needs to
be flushed from the cache module.
