Replacing a RAID Controller – Dual Controllers
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.
Removing the Old Controller
To remove a RAID controller:
1. Disconnect all attached cables from the RAID controller,
2. On the controller handle, squeeze the release tab and pull the handle
outward. See page 255, Figure 5.
3. Pull the RAID controller out of the subsystem enclosure.
Important
• Do not replace the RAID controller based on LED colors
alone. Only replace the RAID controller when directed to do
so by PROMISE Technical Support. See page 351.
• 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 WebPAM PROe, click the AdminTool
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” on
page 252.
Note
On subsystems with dual RAID controllers, you can hot-swap a
controller while the subsystem is running.
