Forced unregistration

Unregistration requires communication between the plug-in appliance and vCenter. In the case that the vCenter is unable to be communicated with, you can force the unregistration of the plug-in from the appliance.

When attempting to unregister using the ibm-plugin unregister command and the vCenter is not able to communicate, the following message appears: 
root@ibm-storage-plugin [ ~ ]# ibm-plugin unregister -u administrator@vsphere.local -v test-vcsa.ssd.hursley.ibm.com
vCenter Password:
Cannot connect to registered vCenter instance at test-vcsa.ssd.hursley.ibm.com.
Do you want to remove this vCenter instance from the local plugin config? [Y/n]
Selecting yes (Y) forces the unregistration at the local appliance level, but does not remove the plug-in from vCenter. Manual removal of the plug-in from vCenter is required to complete this operation.
Manually removing the plug-in from vCenter, when running vCenter 8.0 or later
Plug-ins can now be removed from within the main vSphere Client within environments running vCenter 8.0 or later.
  1. From the Shortcuts menu in the vSphere Client, go to Administration > Solutions > Client Plugins.
  2. Select the vSphere Plugin plug-in.
  3. Select the specific plug-in to be removed, and click REMOVE.
  4. The Remove Instance displays, confirming the removal of the plug-in. Click YES.
  5. When prompted, refresh the browser to complete the plug-in removal.
