    No. For array snapshot methods, there is a piece of software that is installed on the client and the media server. This software contains all the utilities and commands that needs to be used to perform checks, snapshots, break-off of mirror, etc. 
    These utilities normally have a username and password that needs to be supplied during initial NBU config (and when anything has changed). Detailed steps for each supported array type is in the Snapshot Client manual.

    As I've said above, I am not familiar with HDS tools, but I have assisted with similar configs with EMC and HP array clones/mirrors.

    The Snapshot Client manual contains steps such as:
    Steps to be performed by storage admin.
    Steps to be performed by NBU admin.

    Please go through steps in the manual as if it is a new config to verify setup.

You forgot to tell us NBU version on the client?

Any reason why media sever is still on NBU 6.5? 
Are you aware of the fact that NBU 6.x ran out of support in 2012?
Why not upgrade? This will at least enable you to log a Support call should our efforts to assist fail.

Have you tested the process using the HDS tools?

I see this in bpfis log:

vfm_configure_fi_one: read credentials file failed

and what you have also seen.

 set_devinfo: Could not find targ info for device /dev/sdad

So, my suggestion is to manually test the process that NBU needs to automate.

And to upgrade media server and client....
