PureStorage Plugin hangs or fails to load in vCenter Server

Products

• VMware vCenter Server

Issue/Introduction

PureStorage plugin continuously rotates and hangs in the vCenter UI Client. Plugin fails to initialize or load normally within the interface.

Cause

Duplicate host registrations exist for the same vCenter server under the PureStorage Application configuration. This behavior typically occurs following a vCenter upgrade, where multiple endpoints for the same server conflict within the PureStorage appliance.

Resolution

1. Access PureStorage Appliance via SSH using pureuser account.
2. Verify for Duplicate host registration for the vCenter, using following command:
   
   pureplugin register --host <vcenter-fqdn> --user <vcenter-sso-userID>
   
   Example output:
   
   
   Plugin   Status   Version  Registrations
   vSphere  running  #.#.#.#  vcenter-fqdn
                             vcenter-fqdn                    <---------------------- Duplicate host registration
   
   
3. Unregister one of the duplicate vCenter host registrations, using following command: For more information, refer Unregister the vSphere Plugin
   
   pureplugin unregister --host <vcenter-fqdn> --user <vcenter-sso-userID>
   
   
4. Log out and log back into vCenter UI Client.
5. Verify PureStorage plugin loads normally.
