Uninstalling plug-ins from a host using the SnapCenter GUI

When you decide that you no longer require an individual plug-in or a plug-in package, you can uninstall it using the SnapCenter interface.

Before you begin

You must have removed the resource groups for the plug-in package that you are uninstalling.
You must have detached the policies associated with the resource groups for the plug-in package that you are uninstalling.

About this task

You can uninstall an individual plug-in. For example, you might need to uninstall the SnapCenter Plug-in for Microsoft SQL Server because a host is running out of resources and you want to move that plug-in to a more powerful host. You can also uninstall an entire plug-in package. For example, you might need to uninstall the SnapCenter Plug-ins Package for Linux, which includes SnapCenter Plug-in for Oracle Database and SnapCenter Plug-in for UNIX.

Removing a host includes uninstalling all plug-ins.
When you remove a host from SnapCenter, SnapCenter uninstalls all the plug-in packages on the host before removing the host.
SnapCenter GUI removes plug-ins from one host at a time.
When you use the SnapCenter GUI, you can uninstall plug-ins on only one host at a time. However, you can have several uninstall operations running at the same time.

You can also uninstall a plug-in from multiple hosts by using the command-line interface (CLI).

Attention: Uninstalling the SnapCenter Plug-ins Package for Windows from a host on which the SnapCenter Server is installed will damage the SnapCenter Server installation. Do not uninstall the SnapCenter Plug-ins Package for Windows unless you are certain that you no longer require the SnapCenter Server.

Steps

In the left navigation pane, click Hosts.
In the Hosts page, click Managed Hosts.
In the Managed Hosts page, select the host from which you want to uninstall the plug-in or plug-in package.
Adjacent to the plug-in that you want to remove, click Remove > Submit.

After you finish

After you uninstall a plug-in, you must wait for 5 minutes before you reinstall the plug-in on that host. This time period is sufficient for the SnapCenter GUI to refresh the status of the managed host. The installation fails if you immediately reinstall the plug-in.
