Find the High-Availability Configuration content for your version of ONTAP 9
b. After the giveback has been completed, confirm that the HA pair is healthy and that takeover is
possible:
storage failover show
The output from the storage failover show command should not include the System ID changed
on partner message.
7.
Verify that the disks were assigned correctly:
storage disk show -ownership
The disks belonging to the replacement controller should show the new system ID. In the following
example, the disks owned by node1 now show the new system ID, 1873775277:
node1> `storage disk show -ownership`
Disk Aggregate Home Owner DR Home Home ID Owner ID DR Home ID
Reserver Pool
----- ------ ----- ------ -------- ------- ------- -------
--------- ---
1.0.0 aggr0_1 node1 node1 - 1873775277 1873775277 -
1873775277 Pool0
1.0.1 aggr0_1 node1 node1 1873775277 1873775277 -
1873775277 Pool0

If the system is in a MetroCluster configuration, monitor the status of the controller:
metrocluster node
show
The MetroCluster configuration takes a few minutes after the replacement to return to a normal state, at
which time each controller will show a configured state, with DR Mirroring enabled and a mode of normal.
The
metrocluster node show -fields node-systemid command output displays the old system
ID until the MetroCluster configuration returns to a normal state.
9. 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.
Disk ownership changes during HA takeover and MetroCluster switchover in a four-node MetroCluster
configuration

If your system is in a MetroCluster configuration, verify that each controller is configured:
metrocluster
node show - fields configuration-state
