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 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.
On a 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.
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.
Working with Ethernet switches
Use the following sections when designing, configuring, or servicing a Gigabit Ethernet switch that
is part of an existing K2 SAN.
Design considerations for Ethernet switches
The following information was qualified using the HP ProCurve switch. You must use the HP
ProCurve switch for iSCSI traffic. However, for control and FTP/streaming traffic, it is allowed to
use a different brand of switch, such as a Cisco Catalyst switch, if required by your site. If you are
using a non-HP switch, apply the information accordingly. Refer to the documentation you received
with the switch as necessary.
