Replacing the Controller in a Single Controller Configuration
Use the following steps in “Removing the Controller in a Single
Controller Configuration” and “Installing the Controller in a Single
Controller Configuration” to replace the controller.
Removing the Controller in a Single Controller
Configuration
Use the following steps to remove the controller:
1. From the host console, dismount the logical units in the subsystem. If
you are using a Windows NT platform, shut down the server.
2. If the controller is operating, connect a PC or terminal to the controller’s
maintenance port.
If the controller is not operating, go to step 5.
3. Run FMU to obtain the last failure codes, if desired.
Note If you initialized a container with the SAVE_
CONFIGURATION switch (see page B–73), you can save this
controller’s current device configuration using the CONFIGURATION
SAVE command (see page B–49). If CONFIGURATION SAVE is not
used, you will have to manually configure the new controller as
described in Chapter 2, “Configuring an HSG80 Array Controller.”
Caution The cache module may contain data if the controller crashed
and you weren’t able to shut it down with the SHUTDOWN
THIS_CONTROLLER command.
4. Shut down the controller with the following command:
SHUTDOWN THIS_CONTROLLER
When the controller shuts down, its reset button and the first three
LEDs are lit continuously.
Caution ESD can easily damage a controller. Wear a snug-fitting,
grounded ESD wrist strap.
5. Remove the program card’s ESD cover and program card. Save them for
the replacement controller.
