 2. For the operational controller, complete the following substeps:
 a. Connect the PC or terminal to the maintenance port of the operational
controller.
Note: The controller connected to the PC or terminal becomes “this controller.” The
controller for the cache module being removed becomes the “other controller.”
 b. Display and note the 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
 c. Disable failover and take the controllers out of the dual-redundant
configuration by entering the following command:
SET NOFAILOVER
 d. Start the FRUTIL by entering the following command:
RUN FRUTIL
FRUTIL automatically asks you if you want to replace the controller
cache battery.

 f. Enter 1 for the Replace or remove a controller or cache module option.
 g. Enter 3 for the Other cache module option.
 h. Enter Y(es) to confirm the intent to remove the slot x cache module.
FRUTIL quiesces all device ports, indicates a 2-minute limit to remove
the cache module, and begins counting down the time in 10-second
intervals.
Caution: Wait for FRUTIL to quiesce the device ports—indicated by an “All
device ports quiesced” message. Failure to allow the ports to quiesce
can result in data loss. Quiescing might take several minutes.
