[maint] flush
cid
[
uid
...]
This command allows you to flush the write cache on the specified unit or all
units associated with controller
cid
. This command does not apply to Spare
unit types.
[maint] verify
cid uid
[stop]
This command starts or stops a background verification process on the
specified unit. To start, omit “stop”.
The following table shows the supported RAID types for verification as a
function of controller model and logical unit type. N/A (Not Applicable)
refers to cases where the given logical unit type is not supported on a
particular controller model.
[maint] mediascan
cid
start|stop
This command applies to 7000/8000 controllers. It provides media scrubbing
for validating the operationality of a disk, including bad block detection and
remapping. The start or stop operations start or stop media scan operation on
the specified controller. For the 9000 series, the verify function includes the
features of the media scan command.
[maint] commit
cid
This command only applies to the Windows operating system.
This command instructs the controller to commit its dirty DCBs to persistent
storage (disks). While the controller is processing I/O requests against
underlying disks, an in-transaction bit is set. If a failure (such as power
failure) is experienced, subsequent reads from the disk inform the controller
that an un-clean shutdown took place. This command allows the end user to
complete all pending I/Os on disks and clear the in-transaction bit.
Typical application of this feature is when an application is using a given unit
in raw mode (such as databases) and the user would like to shut down the host
(including UPS post failure automations). This command expedites the
process by instructing the controller to finish pending requests and clear the
DCBs in-transaction flag as the disk is going down.
