The RAID controller monitors and manages the logical drives. When the RAID controller is replaced, all of your
logical drive data and configurations remain intact because logical drive information is stored on the physical
drives.
Important
Do not replace the RAID controller based on LED colors alone. Only replace the RAID
controller when directed to do so by ASUS Storage Technical Support.
The firmware version and amount of SDRAM must be the same on the replacement RAID
controller and the other RAID controller in the subsystem.
To obtain firmware and SDRAM information for an installed RAID controller, in ASUS Storage
Management, click the Administration button then click the Image Version icon.
Replacement RAID controllers to not come with a BBU. Remove the BBU from the old
controller and install it into the new one. See Replacing a Cache Backup Battery.
Note
On subsystems with dual RAID controllers, you
can hot-swap a controller while the subsystem is
running.
