SELFTEST THIS_CONTROLLER

Runs a self-test on this controller.

Format

SELFTEST THIS_CONTROLLER

Description

The SELFTEST THIS_CONTROLLER command ﬂushes all user data from this

controller’s write-back cache (if present), shuts down this controller, then restarts

it in DAEMON loop-on-self-test mode. The OCP reset (//) button must be pressed

to take this controller out of loop-on-self-test mode.

If any disks are online to this controller, the controller does not self-test unless

the OVERRIDE_ONLINE qualiﬁer is speciﬁed (HSD and HSJ only). If any

user data cannot be ﬂushed to disk, the controller does not self-test unless the

IGNORE_ERRORS qualiﬁer is speciﬁed.

Specifying IMMEDIATE causes this controller to self-test immediately without

ﬂushing any user data to the disks, even if drives are online to a host.

Note

If you enter a SELFTEST THIS_CONTROLLER command, and you

are using a virtual terminal to communicate with the controller, the

connection is lost when this controller starts the self-test.

Qualiﬁers for HSD and HSJ Controllers

IGNORE_ERRORS

NOIGNORE_ERRORS (Default)

If errors result when trying to write user data, the controller does not start the

self-test unless IGNORE_ERRORS is speciﬁed.

If the IGNORE_ERRORS qualiﬁer is speciﬁed, the controller starts the self-test

even if all customer data cannot be written to disk from the write-back cache.

CAUTION

Customer data may be lost or corrupted if the IGNORE_ERRORS

qualiﬁer is speciﬁed.

IMMEDIATE

NOIMMEDIATE (Default)

If IMMEDIATE is speciﬁed, the controller will immediately start self-test without

checking for online devices or ﬂushing user data from write cache to disk.
