3. Click Open.
The Progress Report window appears showing the disk firmware download task
and the percentage completion.
4. Perform step 1 through step 3 to upgrade disk drives for the remaining controllers.
5. When finished, reboot the RAID storage and the Profile XP Media Platform. Refer
to “System reboot procedure” on page 94.
NOTE: If your PFR700 is part of an Open SAN, disregard the previous step, and
refer to the instructions in the Open SAN Instruction Manual for powering-off and
powering-on the Open SAN.
This concludes the Loading Disk Firmware procedure.
Replacing a failed disk module
In the event of a disk drive failure, you’ll repair the system by replacing the disk module
as soon as possible. Refer to the PFR 700 Instruction Manual for information on
removing and replacing disk modules.
NOTE: Always use GVG Disk Utility to physically identify the failed disk module.
Accidently removing the wrong disk module can destroy all media on the disk
drives. See “Identifying disk modules prior to removal” on page 3-98.
On inserting the replacement disk module, the RAID controller automatically starts
rebuilding the drive. You can verify rebuild status by looking at the disk access LED on
the front of the disk module, or by checking disk status in GVG Disk Utility.
To check disk status in GVG Disk Utility, select the disk module icon in the device tree.
Status is reported in the right-hand pane. On completion, the disk drive status changes
from Rebuilding to Online. You may need to refresh the GVG Disk Utility display.
Disabling a PFR700 RAID controller for removal
This feature is provided for PFR700 RAID chassis that have redundant RAID controller
modules installed. In the event that one of the RAID controllers appears operational, but
also reports faults through various log files and status indicators, you can choose to
disable the controller and replace it. Disabling the controller and removing it in this way
avoids interruptions in signal output that can occur if the module fails or if it is simply
hot swapped while it is the active controller. When the replacement RAID controller
module is installed, it is automatically enabled and becomes the backup controller.
NOTE: Refer to the PFR 700 Instruction Manual for procedures on removing and
replacing the RAID controller module.
To disable a controller:
1. Start the GVG Disk Utility.
2. Expand the tree view to display the controllers.
3. Right-click a controller icon in the tree view, then select Advanced | Disable A
Controller or Disable B Controller .
