We have 10 drives configured from Quanutm i500. All drive are shared with 6 windows media servers. Master is VM and does not control robot.
Among these, 4 Drives are also configured (shared) with 2 Netapp hosts ( 2 each). NMDP drives are configured to media server bck04 which is also the robot control host.
NetApp ontap - 8.1.2 (7-Mode), NBU 7.5.0.6 on windows 2008 R2 64 bit.
The problem is after the nmdp backup is successfully done the netbackup tries to umount the tape but it fails and eventually down only the NDMP path.

I have attached the robot logs.
The backup runs fine on other drives and netbackup does not down other paths. We have to up the ndmp path everyday so that ndmp backup completes.
