Replacing a K2 10Gv2 RAID controller
The K2 10Gv2 RAID controller must be connected to the control network to support the operations
in this topic.
If the RAID chassis has a single controller (non-redundant), you must take the K2 SAN offline
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 configured 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 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.
