- In the Take snapshot window, input name as pre-graceful restart, description as pre-graceful restart and untick "Include virtual machine's memory".
- After the snapshot process is done bring the cluster back Online.
To force the Replica node to take over the Primary role:
- Log in to the Admin UI on the Primary node using the URL:
https://IP_or_FQDN/admin
Note: Replace IP_or_FQDN with the IP address of FQDN of the Primary node.
- Select the current Primary node and click Take Node Offline/Online. Enter a reason in the Take Node Offline/Online dialogue box and then click OK.
- Wait 15 minutes for the change to take effect. The Cluster Role value for the Replica node changes to Primary.
Note: The previous Primary node may still be listed as having the Primary role. You may see two Primary nodes listed.
- With the original Primary node still selected, click Take Node Offline/Online again.
- Enter a reason in the Take Node Offline/Online dialogue box and click OK.
