Procedures for Array Controller Software V8.7x-x Release Notes
Note: A countdown timer allows you a total of 2 minutes to remove the cache module.
After 2 minutes, “this controller” will exit
FRUTIL , restart the "other controller,” and
resume operations. If this happens, perform the following steps:
1. Connect the PC or terminal to the "other controller."
2. Shut down the "other controller" by issuing the command:
SHUTDOWN THIS_CONTROLLER
3. Disconnect the PC or terminal, and reconnect it to the operational controller.
4. Return to substep 2d, and proceed.
 3. For the cache module to be replaced, complete one of the following two
options:
 ■ For StorageWorks Model 2100 and 2200 enclosures, disengage both
retaining levers, and remove the “other controller” cache module.
 ■ For all other supported enclosures:
 a. Disengage both retaining levers and partially remove the “other
controller” cache module—about halfway.
Caution: You must disable the ECB before disconnecting the ECB Y-cable from
the cache module. (If the ECB status light is off, this indicates that the ECB is
disabled.) Failure to disable the ECB can result in cache module damage.
 b. Disable the ECB by pressing the battery disable switch until the status
light stops flashing. This should take approximately 5 seconds.
 c. Disconnect the ECB Y-cable from the “other controller” cache
module.
 d. Remove the cache module from the enclosure.
 4. For the operational controller, observe that FRUTIL restarts I/O ports,
disables writeback caching and mirrored writes, indicates that the mirrored
cache is disabled, and terminates.
 5. For the operational controller, place the cache module on an antistatic bag or a
grounded antistatic mat.
