Backup for Nutanix fails with status code 6
When a NetBackup Flex scale is upgraded, the NetBackup version also gets upgraded. After upgrade, the AHV backup job fails. This may happen because after upgrade, Nutanix AHV backup job attempts creation of VM snapshot and tries to mount it on the backup host by accessing the /usr/openv/tmp/ntxmnt folder. But this causes backup failure due to insufficient permissions while accessing the folder.

Workaround:
Delete the /usr/openv/tmp/ntxmnt folder on the backup host. The folder is re-created with desired permissions during AHV backup job and backup is successful.
