Device does not support NDMP (DDVTL) (4039641)

Device does not support NDMP (DDVTL)

NDMP Backup jobs will hang with "Waiting for Media."  When the "waiting for media" message is "diagnosed ", it states that the device (DDVTL) does not support backup type: NDMP

This is caused by the VTL creation on the Domain Domain Device.

The Data Domain VTL guide will recommend to create the Data Domain VTL identifier as a "DDVTL".

However, NetVault will recognize this as an unsupported device, because it is qualifying the device hierarchy and the templates we used based on the device name.  This means that we are just seeing it as a Data Domain Device rather than a VTL or standard tape library.

To resolve this issue, the device will have to be first removed from NetVault.

Next, go back to the Data Domain Web interface -> Configuration -> VTL

Re-create the device using the device name/Library Emulation "STK L180" or "IBM TS3500". These are available in the Device Name/Type Dropdown.

Once complete and the VTL is re-created on the Data Domain, the device can be re-added back into NetVault.

If you have already created a Target Set with the previous unsupported device, make sure to update or create a new Target Set to use the newly added Data Domain VTL.
