8. If the controller is in a MetroCluster configuration, depending on the MetroCluster state, verify that the DR
home ID field shows the original owner of the disk if the original owner is a controller on the disaster site.
This is required if both of the following are true:
◦ The MetroCluster configuration is in a switchover state.
◦ The replacement controller is the current owner of the disks on the disaster site.
For more information, see
Disk ownership changes during HA takeover and MetroCluster switchover in
a four-node MetroCluster configuration
topic.
9.
If your system is in a MetroCluster configuration, verify that each controller is configured:
metrocluster
node show - fields configuration-state
node1_siteA::> metrocluster node show -fields configuration-state
dr-group-id cluster node configuration-state
----------- ---------------------- --------------
-------------------
1 node1_siteA node1mcc-001 configured
1 node1_siteA node1mcc-002 configured
1 node1_siteB node1mcc-003 configured
1 node1_siteB node1mcc-004 configured
4 entries were displayed.
10.
Verify that the expected volumes are present for each controller:
vol show -node node-name
11.
If you disabled automatic takeover on reboot, enable it from the healthy controller:
storage failover
modify -node replacement-node-name -onreboot true
Complete system restoration - AFF A900
To complete the replacement procedure and restore your system to full operation, you
must recable the storage, restore the NetApp Storage Encryption configuration (if
necessary), and install licenses for the new controller. You must complete a series of
tasks before restoring your system to full operation.
Step 1: Install licenses for the replacement controller in ONTAP
You must install new licenses for the replacement node if the impaired node was using ONTAP features that
require a standard (node-locked) license. For features with standard licenses, each node in the cluster should
have its own key for the feature.
About this task
Until you install license keys, features requiring standard licenses continue to be available to the replacement
node. However, if the impaired node was the only node in the cluster with a license for the feature, no
configuration changes to the feature are allowed. Also, using unlicensed features on the node might put you
out of compliance with your license agreement, so you should install the replacement license key or keys on
the replacement node as soon as possible.
