Unable to setup direct save with server NWSERVER: no matching IP interface data domain devices for save of client `NWSERVER'; check storage nodes, devices or pools.

Hello,

We are trying to add a new pool on NAS to the existing config on our networker server (version 8.2 with several existing pools on Data Domain resources works without problem).

The NAS in question is mounted on the networker server:

     1.1.1.1:/NAS           988281250048    114688 988281135360   1% /NAS

And the device resource is created and online:

$ nsradmin -c "type:NSR device"

1 of 93 (on NWSERVER)

                        type: NSR device;

                        name: NASPool;

                     comment: Device en local;

                 description: ;

   device access information: /NAS;

        enable fibre channel:  Yes   [No];

      fibre channel hostname: ;

                message_I18N: mounted adv_file disk NASPool.004;

                     message: mounted adv_file disk NASPool.004;

                 volume name: NASPool.004;

                media family:  tape   [disk]   cloud    logical ;

                  media type: 

                              ....[adv_file]

                     enabled: [Yes]   No    Service ;

                   read only:  Yes   [No];

And Pool:

$ mminfo -q "family=disk" -r "volume,pool"

volume        pool

...

NASPool.004  NASPool

But any attempt from same networker server or NMC to make a backup or a clone (that the final objective of this new resource make a clone of the existing backups on the NAS) fails with with the same type of error:

1) save -b NASPool /nsr/logs

79625:nsrclone: Failed to clone any Regular save sets

Any suggestions? We have looked at the documentation exhaustively but we can not find what is missing (obviously) by configuring?

Regards
