Replacing the NVRAM adapter

To replace a failed NVRAM card, you must remove the NVRAM riser, Riser 1, from the controller module, remove the failed

card from the riser, install the new NVRAM card in the riser, and then reinstall the riser in the controller module. . Because the

system ID is derived from the NVRAM card, if replacing the module, disks belonging to the system are reassigned to the new

system ID.

Before you begin

• All disk shelves must be working properly.

• If your system is in an HA pair, the partner node must be able to take over the node associated with the NVRAM module

new NVRAM module. You must reassign the disks when directed to in the procedure. Completing the disk reassignment

before giveback can cause issues.

• You must replace the failed component with a replacement FRU component you received from your provider.

• You cannot change any disks or disk shelves as part of this procedure.

• If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy node shows
