NVP vProxy: 19.10 "Fallback to NBD for IDE" Option No Longer Available

After NetWorker upgrade to 19.10, the vProxy appliance no longer has a "Fallback to NBD for IDE disks Option."

The vProxy appliance must have both NBD and HotAdd sessions enabled:

Concern: The Auto selection mode is not isolated to select IDE disks. If the vProxy's HotAdd sessions are exceeded, then it starts to use NBD sessions, even if the VM/disk supports hot add. This can result in the Virtual Machines (VM) with IDE disks waiting for an NBD session to free up. 
Request: Backup admin does not want VMs which support HotAdd to use NBD; even if this means that the backup fails. The backup admin only wants backups of IDE disks to backup using NBD. 

This functionality was changed as per Request For Enhancement to "Fallback to NBD regardless of underlying condition"

This was raised to NetWorker engineering. 

NetWorker 19.10.0.5 and 19.11.0.2 release include code changes to redo the Broker agent implementation so it works both with new and old features. Upgrade to one of these releases (or later).

Ensure to upgrade the vProxy appliance to the latest release supported by your NetWorker server:

• NVP vProxy: NetWorker vProxy Version Information
• NVP vProxy: How To Upgrade the NVP vProxy Appliance Using nsrvproxy_mgmt

Workaround:

Isolate the VMs with IDE disks into a VMware Protection Group. Configure a Protection Policy to backup this group using Auto vProxy selection. Manually select a vProxy which has both hot add and NBD sessions enabled. 

To identify which VMs in the VMware environment have IDE disks perform the following:
1. On the NetWorker server, run the following command from an Administrator command-prompt, or root shell:

nsrvim -d VCENTER_NAME

This creates a VCENTER_NAME.xml file.
Linux: /nsr/cores/nsrvim/
Windows: .xml files are generated in the directory from which the nsrvim command was run. 

2. Filter the VCENTER_NAME.xml for idePresent. This can be done using an .xml reader or from the command line.

Linux: 

xmllint --format /nsr/cores/nsrvim/VCENTER_NAME.xml | grep -B3 -i idePresent

Example:

nve:~ # xmllint --format /nsr/cores/nsrvim/vcsa.amer.lan.xml | grep -B3 -i idePresent
          <filename>[esx01-datastore] win-client01/win-client01_1.vmdk</filename>
          <datastore>esx01-datastore</datastore>
        </virtual-disk>
        <idePresent>TRUE</idePresent>
