Symantec Netbackup : Oracle restore fails "exited with status 13: file read failed"

I am restoring Oracle datafile size of 1200GB. Datafile is read from backup piece size of 4000GB(4TB).

Note: As I monitored 4TB is processed totaly to read all blocks of my datafile.

I had several problems during restore:

Situation 1. There was period when after 2 hours restore was failing (Operation column in Netbackup Database Console was empty at that moment)

Situation 2. Drive was mounted before 2 hours and restore process was not failed before 2 hours. But suddenly restore failed after processing 55GB.

I don't have old logs. Now I the following problem:

• Restore has failed after processing 3TB(23 hours was passed)... I will post some log entries, please help :
