CLI Commands

IMMEDIATE_SHUTDOWN

NOIMMEDIATE_SHUTDOWN (Default)

Instructs the controller whether to flush the write-back cache or not.

CAUTION: The IMMEDIATE_SHUTDOWN switch instructs the controller

to immediately shut down, without regard to any data contained within

write-back cache. See “Fault-Tolerance for Write-Back Caching,”

page 2–11, for considerations when implementing write-back cache. Do

not perform any hardware changes until the controller flushes the

cache.

Select IMMEDIATE_SHUTDOWN to instruct the controller to run the self-test

program immediately without checking for online devices or without flushing user

data from write-back cache to devices.

Select NOIMMEDIATE_SHUTDOWN to instruct the controller to flush data from

write-back cache before running the self-test program.

Examples

This example shows how to start the self-test program on “this controller:”

SELFTEST THIS_CONTROLLER

This example shows how to run the self-test program on the “other controller,” even if

the “other controller” cannot flush all data from the write-back cache:

SELFTEST OTHER_CONTROLLER IGNORE_ERRORS
