When the SnapCenter Server removes a host, it first removes the backup, clones, clones jobs, resource groups, and resources listed for that host in the SnapCenter Resources page, and then it uninstalls the plug-in packages on the host.
Before you begin
- You must be assigned a role with permissions to remove all of the objects associated with the host. Otherwise, the remove operation fails.
- You should confirm the fingerprint if the SSH key was modified after adding the host to SnapCenter.
- You should confirm the fingerprint if the SnapCenter host is upgraded to a later version of SnapCenter but the plug-in host is still running an earlier version of the plug-in.
About this task
- If you delete a host, the backups, clones, and resource groups associated with the host are also deleted.
- When you remove the resource groups, all the associated schedules are also removed.
- If the host has a resource group that is shared with another host and you delete the host, then the resource group is also deleted.
- You must use PowerShell cmdlet to remove the decommissioned or unreachable SnapCenter Server hosts.
Steps
- In the left navigation pane, click Hosts.
- In the Hosts page, click Managed Hosts.
- Select the host you want to remove, and then click Remove.
- For Oracle RAC clusters, to remove SnapCenter software from all the hosts in the cluster, select Include all the hosts of cluster.
You can also remove one node of a cluster and in that way remove all the nodes one by one. However, if there are no backups associated with a node, select Delete backups to remove the host from the RAC cluster.
- Click OK.
