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.
If you manually installed the Plug-in for VMware vSphere, then you must configure a Run As credential before you uninstall the plug-in.

About this task

You can uninstall an individual plug-in. For example, you might need to uninstall the SnapCenter Plug-in for VMware vSphere 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).
Uninstalling SnapCenter Plug-in for VMware vSphere
- When you uninstall SnapCenter Plug-in for VMware vSphere, the plug-in is also unregistered with vCenter.
- If you installed the Plug-in for VMware vSphere manually, then you must do one of the following:
  - Manually uninstall the plug-in.
  - Manually set up Run As credentials and then use the SnapCenter Server GUI to uninstall.

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.
Click Modify.
In the Modify Host page, select Remove plug-ins.
In the Plug-ins page, do the following:
- If you are uninstalling a single plug-in, do not make any selection on this page.
- If you are uninstalling a plug-in package, select the package you want to uninstall.
In the Summary page, review your selections and then click Finish.

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.

If you are uninstalling SnapCenter Plug-ins Package for Linux, uninstallation-specific log files are available at: /custom_location/snapcenter/logs.
