Maintenance and Service Guide

Removing a GLM

Use the following steps to remove a GLM in dual-redundant configurations:

1. Connect a PC or terminal to the maintenance port of the operational

controller.

Note: The controller connected to the PC or terminal becomes “this controller,” and

the controller being removed becomes the “other controller.”

2. Disable failover and take the controllers out of the dual-redundant

configuration with one of the following commands:

SET NOFAILOVER

SET NOMULTIBUS_FAILOVER

3. Start the FRUTIL with the following command:

RUN FRUTIL

4. Enter N(o) to the question about replacing the cache battery.

5. Enter 1 for the remove a controller or cache module option.

6. Enter 2 for the remove “other controller” option.

7. Enter Y(es) to confirm the intent to remove the “other controller.”

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 can take several minutes.

Note: A countdown timer allows a total of 2 minutes to remove the controller. After 2

minutes, “this controller” exits

FRUTIL

and resumes operations. If this happens, return

to step 3 and proceed.
