TSM lan free backup using IBM tape error lin_tape 9:0:1:0: reservation conflict

Hello,
I have RHEL 5.10 and i try to perform lan free backup using TSM client and Tivoli storage agent.
I installed as well lin_tape drive but same error on each check:

lin_tape 9:0:1:0: reservation conflict

Tapes are maped by system like below, in /dev/tape/by-id/, so I suppose i have to create persistem rules, to be used as /dev/IBMtapeX as in this format are defined in TSM server.

ls -la /dev/tape/by-id/
lrwxrwxrwx 1 root root 10 Sep 20 11:35 scsi-3500507630f324804-sg -> ../../sg85
lrwxrwxrwx 1 root root 10 Sep 20 11:35 scsi-3500507630f324806-sg -> ../../sg86
lrwxrwxrwx 1 root root 10 Sep 20 11:35 scsi-3500507630f324808-sg -> ../../sg87

Does have somebody a clue how it should be done?
Thank you
