migrate name raid0 stripe-depth device_list
Migrate a RAID 0 array with the specified stripe depth and devices. You must
specify at least two devices.
migrate name raid5 stripe-depth device_list
Migrate a RAID 5 array with the specified stripe depth and devices. You must
specify at least three devices.
migrate name raid10 stripe-depth device_list
Migrate a RAID 10 array with the specified stripe depth and devices. Devices are
automatically grouped into pairs, and therefore must always be an even number.
destroy unused_or_alien_array_list
Destroy the listed arrays. When the arrays are destroyed, the disks and RAID
groups associated with them become available for use.
Note: Arrays assigned to logical drives cannot be destroyed. Foreign arrays
must be imported before they can be destroyed.
An alien array is an array with an incomplete or corrupted signature that cannot
be used.
export name_list
Export the arrays in name_list. When these arrays are exported, the disks in
those arrays are no longer available.
If all of the disks in a array are transferred to another system, they can be used in
that system after you complete an array import. (See import name_list.)
array failback
Return all storage to its original controller, if it has been moved (failed over). The
original controller, from which the array was removed, must be functional again
before you use this command.
identify [start | stop] name_list
Identify the devices that make up the arrays in name_list, or all of the disks that
are assigned to any array if name_list is not supplied.
Disks are identified by flashing LEDs; flashing continues for 30 seconds or until
an array identify stop or device identify stop command is given for that
disk.
