Replacing a RAID Controller
The RAID Controller monitors and manages the logical drives. When the
controller is replaced, all of your logical drive data and configurations remain
intact because this logical drive information is stored on the disk drives.
RAID Controller failure is rare. But you might have to remove and reinstall the
same RAID Controller in order to replace a cooling fan, cache battery, or memory
module as described in this chapter.

1.
Shut down the VessRAID. See "Shutting Down the Subsystem" on page 80

2.
