CLI Commands B–99
SELFTEST controller
Flushes the data from the specified controller’s write-back cache (if
present) and shuts down the controller. It then restarts the controller in
self-test mode. Press the controller reset (//) button to take the controller
out of self-test mode.
Syntax
SELFTEST controller
Parameters
controller
The controller parameter indicates which controller is to perform the
self-test program. Specify OTHER_CONTROLLER or
THIS_CONTROLLER.
Switches
IGNORE_ERRORS
NOIGNORE_ERRORS (Default)
Instruct the controller how to respond to write-back cache errors.
Caution The IGNORE_ERRORS switch might cause data to remain in
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.
Specify IGNORE_ERRORS to instruct the controller to ignore any
write-back cache errors. Such errors can result from data contained
within write-back cache unable to be written to the devices or lost data
errors.
Specify NOIGNORE_ERRORS to instruct the controller not to run the
self-test program if the write-back cache errors are detected.
IMMEDIATE_SHUTDOWN
NOIMMEDIATE_SHUTDOWN (Default)
Instructs the controller whether to flush the write-back cache or not.
