Remove a host
When the SnapCenter Server removes a host, it first removes the backup, clones, clone jobs, resource groups, and resources listed for that host on the SnapCenter Resources page, and then it uninstalls the plug-in packages on the host.
-
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 should use the Remove-SmHost cmdlet to remove the decommissioned or unreachable plug-in hosts.
The information regarding the parameters that can be used with the cmdlet and their descriptions can be obtained by running Get-Help command_name. Alternatively, you can also refer to the SnapCenter Software Cmdlet Reference Guide
-
The time required to remove a host depends on the number of backups and the retention settings. This is because the Snapshots are deleted from each of the controllers and the metadata is cleaned.

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.

Click OK.
When you uninstall and reinstall host plug-ins on a cluster, the cluster resources are not automatically discovered. Select the cluster hostname, and then click Refresh Resources to automatically discover the cluster resources.
