flush cache
The "flush-cache" command flushes
the controller's cache. The system
automatically flushes the cache at
shutdown or if the driver module is
unloaded, so this command is only
needed to be certain a write back cache
is flushed to disk before the system is
powered off by a command to a UPS.
Note that the flush-cache command also
stops an asynchronous rebuild or
consistency check, so it should not be
used except when the system is being
halted.
make online
The "make-online" command changes the
physical drive {channel}:{target-id}
from status DEAD to status ONLINE. In
cases where multiple physical drives
have been killed simultaneously, this
command may be used to bring them
back online, after which a consistency
check is advisable.
Warning: make-online should only be
used on a dead physical drive that is
an active part of a drive group, never
on a standby drive.
standby
The "make-standby" command changes
physical drive {channel}:{target-id}
from status DEAD to status STANDBY. It
should only be used in cases where
a dead drive was replaced after an
automatic rebuild was performed onto a
standby drive. It cannot be used to add
a standby drive to the controller
configuration if one was not created
initially; the BIOS Configuration
Utility must be used for that currently.
rebuild
The "rebuild" command initiates an
asynchronous rebuild onto physical
drive {channel}:{target-id}. It
should only be used when a dead
drive has been replaced.
consistency
The "check-consistency" command
initiates an asynchronous consistency
check of {logical-drive-number} with
automatic restoration. It can be used
whenever it is desired to verify the
consistency of the redundancy
information.
