HPDP 9.05 Object Copy NDMP from VTL to physical tape

Hello,

I have HPDP 9.05 on W2K12 R2 and NetApp with 8.1.4 OnTape version and Quantum DXi4700 VTL with deduplication and Quantum i80 with 80 slots and 2x LTO6 drives. Drives from VTL and LTO6 drives connected to NetApp as mc1 and mc2 changers and nrst0a and nrst3a tape device.

NDMP backup to VTL and to LTO6 drive works fine. BUT object copy from VTL to LTO6 drive does'nt work.

Errors from session on NDMP VTL drive:

NETWORK RESTORE: Already at the end of tape. 

NETWORK RESTORE: RESTORE NETWORK IS ABORTED

MOVER: Tape reading operation terminated

NDMP Restore operation has failed.

BUT, restore from NDMP VTL tape to NetApp volume works normally.

Can anybody help me?

Thanks very much.
