Maintenance and Service Guide
Replacing a GLM in single-controller configurations
Use the steps in “Removing a GLM” and “Installing a GLM” on page 60 to
replace a GLM in a single-controller configuration.
Caution: Static electricity can easily damage a controller or GLM. Wear a
snug-fitting, grounded electrostatic discharge (ESD) wrist strap.
Removing a GLM
Use the following steps to remove a GLM in single-controller configurations:
1. Check the controller to make sure it is operating.
■ Connect a PC or terminal to the controller maintenance port for the failed
GLM if the controller is operating.
■ Go to step 6 on page 59 if the controller is not operating.
2. From the host console, stop all host activity to the controller and dismount the
logical units in the subsystem.
3. If you are using a Microsoft
® Windows 2000® or Windows NT® platform,
shut down the server.
4. Run the Fault Management Utility (FMU) to obtain last failure codes, if
desired.
5. Shut down “this controller” with the following command:
SHUTDOWN THIS_CONTROLLER
Note: After the controller shuts down, the Reset button and the first three port LEDs
turn on (see Figure 20 on page 59). This process can take several minutes, depending
on the amount of data that needs to be flushed from the cache module.
