The configuration of one of our NetBackup Media Servers on AIX 5.1 make me
some problems.

Environment (NetBackup Data Center):
NetBackup Master Server (NBU 3.4 patch NB_34_3, Solaris 8), NetBackup Media
Server (NBU 3.4 patch NB_34_3, AIX 4.3.3), ACS-Server (ACS 6.0, AIX 4.3.3),
3 STK9840-Tape Drives

Target:
The OS of the NetBackup Media Server should be changed to AIX 5.1

Sofware:
VERITAS NetBackup 3.4 for AIX 5L Version 5.1

Problem after a Test-Backup:
02/10/2003 15:03:40 - connecting
02/10/2003 15:03:40 - connected; connect time: 000:00:00
02/10/2003 15:03:50 - mounting 250847

The Backup terminate with Code 57. But the tape is mounted on the drive. Now
i can only dismount the tape through the ACS-server.

Error:
db_lock_media: unable to lock media
