B–100 HSG80 User’s Guide

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 1–21 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:
