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. 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 into the configuration level of the program with the ssconfig password.
SANscape displays the Make or Change Standby window.
If you want to select a different server or controller, click Cancel to return
to the SANscape tree view, select the correct server or controller from the tree view, and repeat steps 2 and 3.
