Missing Entry in the Instance Selector

A plug-in instance is missing from an Instance Selector.

Cause

This problem can occur only in an ELM environment, where multiple vCenter Server instances are linked. The plug-in instance entry is missing because the plug-in from the vCenter Server instance did not download or deploy the plug-in correctly.

Solution

Verify that the plug-in is registered with the vCenter Server instance.
Use other troubleshooting topics in Plug-in Does Not Appear in vSphere Client to find out why the plug-in did not download or deploy.
