4.2 Replacing a Controller

The RAID controller monitors and manages the logical drives. When the

controller is replaced, all the logical drive data remains intact because

the logical drive information is stored on the disk drives.

When a controller fails, you can replace the controller with a new one.

The controllers are hot-swappable, which means they can be replaced

even when the RAID system is powered on and functioning.

To replace a faulty controller, follow the procedures below:

1. Disconnect the fiber or SAS cables, mananagement, and serial power

cables connected to the faulty controller.

2. Loosen the screws of the

controller.

Note

Replace the hard disk with the same or greater capacity than the

faulty disk. If the disk is smaller, the audible alert will sound and the

auto-rebuild function will not start.

Note

Before replacing the controller, be sure the replacement controller is

greater or has the same memory capacity as the original controller.

Note

The following illustrations show A16R-FS RAID system, however the

same procedures apply to A12R-FS&SS, A16R-SS, and A24R-FS&SS

RAID systems.
