--recover-array, -rcv
The Recover Array option attempts to force failed arrays back into a functioning state. This option is provided
as a last resort for you to try to recover whatever data might be present after an array has failed and the data
cannot be recreated by the controller.
This option uses
--array
as a qualifier.
--rescan, -rsc
The Rescan Disks option rescans all channels for new or removed disks.
--hide, -h
The Hide Array option hides arrays from the operating system. This feature is useful when it is important to
keep the array data available, but not actively online.
A good example would be when using the split option with RAID1, RAID10, RAID1n, or RAID10n. With this
option, an exact duplicate of the original array (at the time of the split) is made available as a second array.
You may want to hide this array from the operating system and keep it as a backup in case of a catastrophic
failure of the original array or as protection against malicious software.
When you hide an array, the
O.S. Name
is displayed as
Hidden
. This option uses
--array
as a qualifier.
