Virtual machines residing on NFS storage become unresponsive during a snapshot removal operation (2010953)

Symptoms

During a snapshot removal operation, virtual machines residing on NFS storage become unresponsive.
You are using a VADP-enabled backup solution, such as VMware Data Recovery, which uses the hot-add method.
When removing snapshots after backing up a virtual machine residing on an NFS datastore using a backup application, the virtual machine becomes unresponsive for approximately 30 seconds.
Removing snapshots after backing up a virtual machine residing on an NFS datastore takes a long time to complete.
The target virtual machine disk was hot-added for the backup/restore operation.

Cause

This is a known issue which occurs when the target virtual machine and the backup appliance reside on two different hosts.

Resolution

To work around this issue, ensure that the virtual machine resides in the same host where the backup appliance is installed.

Note: As a workaround, you can use the NFC (Network File Copy) transport method in your backup solution or disable SCSI hot-add through the backup software.
