to determine whether you should use this procedure.
If this is the procedure you should use, note that the controller replacement procedure for a node in a four
or eight node MetroCluster configuration is the same as that in an HA pair. No MetroCluster-specific steps
are required because the failure is restricted to an HA pair and storage failover commands can be used to
provide nondisruptive operation during the replacement.
• This procedure includes steps for automatically or manually reassigning drives to the
replacement
node,
depending on your system’s configuration.
You should perform the drive reassignment as directed in the procedure.
• You must replace the failed component with a replacement FRU component you received from your
provider.
• You must be replacing a controller module with a controller module of the same model type. You cannot
upgrade your 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.
• Any PCIe cards moved from the old controller module to the new controller module or added from existing
customer site inventory must be supported by the replacement 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
replacement
node is the new node that is replacing the impaired node.
◦
The
healthy
node is the surviving 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 replacement process.
Shut down the impaired controller - AFF A300
You can shut down or take over the impaired controller using different procedures,
depending on the storage system hardware configuration.
Option 1: Most configurations
To shut down the impaired node, you must determine the status of the node and, if
necessary, take over the node so that the healthy node continues to serve data from the
impaired node storage.
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 false for eligibility and health, you must correct the issue before shutting down the impaired node;

Administration overview with the CLI
