Upgrading to L30 controllers
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.
On a Level 3 or a Level 10/20/30 primary RAID chassis with two controllers, if the
replacement controller’s firmware is not the same as the firmware on the redundant
(currently installed) controller, the firmware on the replacement controller is
automatically upgraded or downgraded to match the current system level firmware.
NOTE: Refer to the Instruction Manual for your RAID storage chassis for
procedures on removing and replacing the RAID controller module.
To replace a controller, do the following:
1. Open the Storage Utility.
2. Expand the tree view to display the controllers.
3. Select the controller and check its status, then proceed as follows:
• If the faulty controller reports as disabled, proceed to the next step in this
procedure.
• If the faulty controller reports as online, right-click the controller icon in the tree
view, and select Advanced | Disable Controller 0 or Disable Controller 1 , then click
OK to continue.
The RAID controller is disabled. You can check controller status in the Storage
Utility. You may need to refresh the display.
NOTE: If you accidentally disable the wrong controller, you can enable it again by
removing it and then replacing it in the chassis.
4. Remove and replace the disabled RAID controller module.
Refer to procedures in the Instruction Manual for your RAID storage chassis.
5. On inserting the replacement RAID controller, it initializes and is automatically
enabled to become the “backup” RAID controller.
Upgrading to L30 controllers
NOTE: Do not attempt this procedure without first consulting Grass Valley
Support.
You can upgrade your RAID chassis from Level 10/20 controllers (NEC D1-10) to
Level 30 controllers (NEC D3-10). If this is part of expanding the media file system,
refer to
“Expanding the media file system by capacity” on page 519 and “Expanding
the media file system by bandwidth” on page 521 .
If you do not change the number of Expansion chassis or their cabling pattern, no
special preparations are required before changing the controllers.
