Replacing a Cache Module in a Single-Controller
Configuration
Use the following steps in “Removing the Cache Module in a Single-Controller
Configuration” and “Installing the Cache Module in a Single-Controller Configuration” to
replace a cache module.
CAUTION: ESD can easily damage a cache module or DIMM. Wear a snug-fitting,
grounded ESD wrist strap.
Removing the Cache Module in a Single-Controller
Configuration
Use the following steps to remove a cache module:
1. From the host console, dismount the logical units in the subsystem. If using a
Windows NT platform, shut down the server.
2. If the controller is operating, connect a PC or terminal to the controller maintenance
port.
If the controller is not operating, go to step 5.
3. Run FMU to obtain the last failure codes, if desired.
4. Shut down the controller with the following command:
SHUTDOWN THIS_CONTROLLER
When the controller shuts down, the reset buttons and the first three LEDs are lit
continuously (see Figure 2–4). Receiving this indication can take several minutes,
depending on the amount of data that needs to be flushed from the cache modules.
CAUTION: The ECB must be disabled—the status light is not lit and is not
blinking—before disconnecting the ECB cable from the cache module. Failure to
disable the ECB might damage the cache module.
