Start or Stop a Task on a Disk or RAID Volume
The start task and stop task subcommands control the
execution of maintenance tasks on a disk or RAID volume.
-
Do one of the following:
-
To start a task on a disk or RAID volume, type:
raidconfig start task -t taskname
[-d|-r]
-
To stop a task on a disk or RAID volume, type:
raidconfig stop task -t taskname
[-d|-r]
The following are command examples for the start task and stop
task subcommands:
-
A RAID ID must be provided for the verify check (verify) and initialization
task (init).
-
To start the verify task on a specified RAID volume, type:
raidconfig start task -t verify
-r=raidvolume
For example:
raidconfig start task -t verify -r=c0r1
-
To stop the init task on a specified RAID volume, type:
raidconfig stop task -t init
-r=raidvolume
For example:
raidconfig stop task -t init -r=c0r1
-
A disk must be provided for the rebuild and clear tasks.
-
To start the rebuild task on a specified disk, type:
raidconfig start task -t rebuild
-d=disk
For example:
raidconfig start task -t rebuild -d=c0d1
Note -
This can only be run on a disk that is part of a RAID volume.
-
To start the clear task on a specified disk, type:
raidconfig start task -t clear
-d=disk
For example:
raidconfig start task -t clear -d=c0d1
Note -
This can only be run on a disk that is not part of a RAID volume.
-
Source and destination disks must be provided for the copy task.
To start the copy task from one disk to another, type:
raidconfig start -task -t copy --src-disk=source_disk
--dst-disk=destination_disk
For example:
raidconfig start -task -t copy --src-disk=c0d2 --dst-disk=c0d3
Note -
The source disk must be in a RAID volume. The destination disk cannot be in a RAID
volume.
The available background tasks are shown in the following table.
|
|
verify
|
Checks the validity of the RAID volume redundant data.
|
init
|
Initializes the RAID volume to write out the initial parity values. The initialization goes
over the entire volume and initializes the parity data.
|
copy
|
Copies and moves an online physical disk onto a hotspare or unconfigured good drive. The copy
is performed while the volume is online. Once completed, the destination disk is added to the
logical volume configuration while the original source disk is removed from it.
|
rebuild
|
Regenerates the data of a single physical disk that is part of a logical volume with data
redundancy. The physical disk is reconstructed from another physical disk and/or parity disks. A
disk rebuild typically occurs after a disk replacement or repair.
|
clear
|
Clears a physical disk by writing zeroes over the entire disk.

Note -
Not all devices support all tasks. To check the tasks a device supports, use the list
subcommand and check the output under Startable tasks. If this field is blank, the device does not
support any tasks.
The start task and stop task subcommands accept the
options shown in the following table.
|
|
|
–t
|
–-task
|
Specifies the type of task to execute. Possible options are verify,
init, rebuild, clear, or
copy.
|
–d
|
–-disk
|
Specifies the disk to execute the task on. Required by the rebuild and
clear tasks.
|
–r
|
–-raid
|
Specifies the RAID volume to execute the task on. Required by the verify
and init tasks.
|
n/a
|
--src-disk
|
Specifies the source disk to use in a copy task.
|
n/a
|
--dst-disk
|
Specifies the destination disk to use in copy task.
