Boot the node:
boot_ontap
Option 3: Manually reassign the system ID on systems in a two-node MetroCluster configuration
In a two-node MetroCluster configuration running ONTAP, you must manually reassign disks to the new
controller’s system ID before you return the system to normal operating condition.
About this task
This procedure applies only to systems in a two-node MetroCluster configuration running ONTAP.
You must be sure to issue the commands in this procedure on the correct node:
• The impaired node is the node on which you are performing maintenance.
• The replacement node is the new node that replaced the impaired node as part of this procedure.
• The healthy node is the DR partner of the impaired node.
Steps
1. If you have not already done so, reboot the replacement node, interrupt the boot process by entering
Ctrl-C, and then select the option to boot to Maintenance mode from the displayed menu.
You must enter
Y when prompted to override the system ID due to a system ID mismatch.
2.
View the old system IDs from the healthy node:
`metrocluster node show -fields node-
systemid
,dr-partner-systemid`
In this example, the Node_B_1 is the old node, with the old system ID of 118073209:
dr-group-id cluster node node-systemid dr-
partner-systemid

In this example, the new system ID is 118065481:
