3. In the Open File dialog box, browse to the desired rmware le for your disks, select the le,
and click OK.
As instructed by a message that appears, watch the lights on the drives. For each drive, one at a
time, the lights ash as rmware loads. Wait until the lights on all the drives on which you are
downloading rmware have completed their ashing pattern. This can take several minutes.
The Progress Report window appears showing the disk rmware download task and the percentage
complete.
4. When nished, restart the K2 Media Server.
Replacing a disk module
If the RAID chassis has a single controller (non-redundant), you must take the K2 SAN ofine
before replacing a failed controller. Refer to procedures in the Instruction Manual for your RAID
storage chassis. The remainder of this procedure does not apply to non-redundant systems.
If the RAID chassis has redundant controllers and is properly cabled and congured for a redundant
K2 SAN, you can replace a failed controller while media access is underway, as described in this
procedure. When a controller detects a fault on its redundant partner controller, the good controller
disables the faulty controller automatically. In most cases an error message informs you of the fault
and when you check the controller’s status in Storage Utility it reports as disabled.
However, you can also manually disable a controller. In the event that one of the RAID controllers
appears operational, but also reports faults through various log les 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.
On a RAID chassis with two controllers, if the replacement controller’s rmware is not the same
as the rmware on the redundant (currently installed) controller, the rmware on the replacement
controller is automatically upgraded or downgraded to match the current system level rmware.
NOTE: Refer to the Instruction Manual for your RAID storage chassis for procedures on removing
and replacing the RAID controller module.
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.
