A standby drive acts as a spare to support automatic data rebuilding after a
physical drive in a fault tolerant (non-RAID 0) logical drive fails. For a
standby drive to take the place of another drive, it must be at least equal in size to the failed drive. Also, the failed drive itself must be from a RAID 1, 3, or 5. You can have one or more
standby drives associated with an array controller.
With this function, you can either assign a global or local standby drive or change a ready drive's state to standby or a standby drive's state to ready.
A drive that is assigned as a global spare rebuilds if a member of an existing drive fails.
You can have one or more standby drives associated with an array controller. Global spares are used in the
order in which they are created. A local spare has to be assigned to a particular
logical drive and only rebuilds for a member within that logical drive.
To assign a global or local standby drive or to change a ready drive's state to standby or a standby drive's state to ready:
If necessary, log in to the configuration level of the program with the ssconfig password.
