"The provider is already registered" error when registering a Pure storage provider

Products

• VMware vCenter Server

Issue/Introduction

While trying to register a VASA storage provider from Pure Storage in vSphere Client, the following error is observed: "The provider is already registered."

Environment

vCenter Server with Pure storage VASA provider

Cause

When one Pure VASA storage provider is changed or removed, the other will take the primary UUID.

Later on, when the removed/changed storage provider is attempted for re-registering, its UUID shows as already registered.

Resolution

1. Unregister both storage providers. Refer: Remove storage provider

2. Register them back in the proper order. Refer: Register storage provider

Note: The Proper order would be to re-register the removed Storage Provider first.
