SHUTDOWN THIS_CONTROLLER

Shuts down and does not restart this controller.

Format

SHUTDOWN THIS_CONTROLLER

Description

The SHUTDOWN THIS_CONTROLLER command ﬂushes all user data from this

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

If any disks are online to this controller, the controller does not shut down unless

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

data cannot be ﬂushed to disk, the controller does not shut down unless the

IGNORE_ERRORS qualiﬁer is speciﬁed.

Specifying IMMEDIATE causes this controller to shut down immediately without

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

Note

If you issue a SHUTDOWN THIS_CONTROLLER command,

communication with the controller is lost when this controller shuts

down.

Qualiﬁers for HSD and HSJ Controllers

IGNORE_ERRORS

NOIGNORE_ERRORS (Default)

If errors result when trying to write user data, the controller is not shut down

If the IGNORE_ERRORS qualiﬁer is speciﬁed, the controller shuts down 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_SHUTDOWN

NOIMMEDIATE_SHUTDOWN (Default)

If IMMEDIATE is speciﬁed, the controller shuts down immediately without

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

CAUTION

speciﬁed.
