Ehh gads i found the problem.
the .namespace.chksum file was whacked, it had a hostname of our old filer and the hotname of the new filer.
Anyhow the extra line that contained the old filer was making "set_ndmp_attr -verify" command fail every once and a while, hence making the drive go down.
log into the filer and reset the user ID and password for NDMP (this is for EMC) but Netapps are slightly different, look at teh pdf for Netapps for modifying the NDMP user ID.
/nas/sbin/server_user server_2 -list
/nas/sbin/server_user server_2 -unlock ndmp
/nas/sbin/server_user server_2 -passwd -unlock ndmp
/nas/sbin/server_user server_2 -passwd ndmp
no log into the master netbackup server.
cd to /usr/openv/volmgr/database
and
rm .namespace.chksum
now
set_ndmp_attr -auth filer_hostname password.
set_ndmp_attr -verify
should get
Connecting to host "filer.name.com" as user "ndmp"...
Waiting for connect notification message...

Host info is:

should be fine.
