Backup proxy that uses Virtual Appliance (HotAdd) mode and is installed on Microsoft Windows 2019 shows "Restart Required" message

Challenge

When users log in to the server on which the backup proxy is installed, they get a request to restart the server. The request message can be one of the following:

• Your PC needs to be restarted to finish setting up this device: LSI Adapter
• Your PC needs to be restarted to finish setting up this device: VMware Paravirtual Adapter

Cause

This is a known issue with hot-add operations on Microsoft Windows Server 2019.

Solution

This issue does not impact performance or functionality. The message can be ignored.

The issue also has a work-around.

For LSI Logic SAS Adapter

• Add a second adapter of the same type.
• Power off the VM where the backup proxy is installed
• Relocate the boot drive to the new adapter (1:0)
• Power on the backup proxy and resume operations

For VMware Paravirtual Adapter

• Add an LSI Logic SAS adapter
• Resume operations
