Replacing the controller module

You must review the prerequisites for the replacement procedure and select the correct one for your version of the ONTAP

operating system.

Before you begin

• All drive shelves must be working properly.

• If your system is in an HA pair, the healthy node must be able to take over the node that is being replaced (referred to in this

procedure as the “impaired node”).

system by just replacing the controller module.

• You cannot change any drives or drive shelves as part of this procedure.

• In this procedure, the boot device is moved from the impaired node to the replacement node so that the replacement node

will boot up in the same version of ONTAP as the old controller module.

• It is important that you apply the commands in these steps on the correct systems:

◦ The

impaired

node is the node that is being replaced.

◦ The

node is the new node that is replacing the impaired node.

• You must always capture the node's console output to a text file.

This provides you a record of the procedure so that you can troubleshoot any issues that you might encounter during the

You can shut down or take over the impaired controller using different procedures, depending on the storage system hardware

configuration.

To shut down the impaired node, you must determine the status of the node and, if necessary, take over the node so that the

• If you have a SAN system, you must have checked event messages (event log show) for impaired node SCSI blade.

Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be resolved before you

proceed with the replacement.

Steps

1. If AutoSupport is enabled, suppress automatic case creation by invoking an AutoSupport message:

Example

The following AutoSupport message suppresses automatic case creation for two hours:

To replace the controller module hardware, you must remove the impaired node, move FRU components to the replacement

controller module, install the replacement controller module in the chassis, and then boot the system to Maintenance mode.

Steps

To replace the controller module, you must first remove the old controller module from the chassis.

Steps

1. If you are not already grounded, properly ground yourself.

2. Loosen the hook and loop strap binding the cables to the cable management device, and then unplug the system cables and

SFPs (if needed) from the controller module, keeping track of where the cables were connected.

Leave the cables in the cable management device so that when you reinstall the cable management device, the cables are

organized.

3. Remove and set aside the cable management devices from the left and right sides of the controller module.

6.

Turn the controller module over and place it on a flat, stable surface.

7. Open the cover by sliding in the blue tabs to release the cover, and then swing the cover up and open.
