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 44 on page 114).
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 status, serial numbers, SCSI mode, and so
forth) for the operational controller by entering the following
command:
SHOW THIS_CONTROLLER
d. Verify that the I/O for the controller that is being replaced fails over
to the operational controller (see substep 1d on page 121) by entering
the following command:
RUN VTDPY
Note: In Transparent Failover mode, units that failed over due to a RESTART
command revert back to the preferred controller after about 1 minute.
