Removing an HSG60 or HSG80 Controller in Dual-Redundant Configurations
Perform the following steps to remove a controller in a dual-redundant controller
configuration.
 1. If the controller to be replaced () is functional, complete the following
substeps. Otherwise, go to step 2 below.
 a. Connect a PC or terminal to the maintenance port of the controller.
 b. Press Enter or Return 2 or 3 times to display the controller prompt.
 c. Start the Virtual Terminal Display (VTDPY) Utility by entering the
following command:
RUN VTDPY
 d. Record which units have I/O activity.
 e. Exit VTDPY by pressing Ctrl+Y.
 f. Restart the controller by entering the following command:
RESTART THIS_CONTROLLER
Note: Restarting the controller ensures that the unit persistent reservation flags transfer
to the operational controller.
 g. Disconnect the PC or terminal from the maintenance port.
 2. For the operational controller (), complete the following substeps:
 a. Connect a PC or terminal to the maintenance port of the operational
controller (see Figure 4 on page 15).
Note: The controller connected to the PC or terminal becomes “this controller.” The
controller being removed becomes the “other controller.”
 b. Set the terminal baud rate to match the controller baud rate, and then press
Enter or Return 2 to 3 times to display the controller prompt.
 c. Display and note configuration information (for example, the Failover
mode, Cache mode, serial numbers, SCSI mode, and so forth) for the
operational controller by entering the following command:
SHOW THIS_CONTROLLER
