Replacing a Failed Controller Canister in the E5660 Controller-
Drive Tray
To access this product, go to the NetApp® support site at mysupport.netapp.com.
You can determine whether you have a failed controller canister in two ways:
The Recovery Guru directs you to replace a failed controller canister.
The amber Controller Service Action Required LED indicates a failed controller canister.
Before you replace the controller canister, gather antistatic protection, a new controller canister, and a controller air
blocker.
When you install a new controller, you must remove the battery from the failed controller, and install it in the new
controller. This procedure includes that task.
ATTENTION Possible loss of data access – Your new controller must have the same host interface card (HIC)
as the controller you are replacing. If the HICs do not match, do not attempt this procedure. The presence of mis-
matched controllers causes your storage array to lock down when you bring the new controller on line. You lose
access to your data until the problem is corrected.
ATTENTION Possible loss of data access – If the controller that you are replacing manages any secure volumes,
the new controller needs the correct security key to manage those volumes. After you replace the controller and
restore power to the controller-drive tray, you can use SANtricity® Storage Manager to load the key from the file in
which it was saved. Be sure that such a file exists and that you know the pass phrase required to install the security
key before you replace the controller.
ATTENTION Possible hardware damage – Because you perform this procedure with the power turned on, the
equipment might overheat if the controller slot is left open for more than three minutes. To prevent the possibility of
overheating, you must insert the controller air blocker into the controller slot when you service the controller.
