I have a stranger behavior in my TSM Server ( at least to me).

TSM Server 5.3.3 on AIX 5.3, tape library 3584 with LTO3 drives.

library on AIX, it shows "tsm_barcode_len 6"

Library definition on TSM Server as:
DEFINE LIBRARY 3584 LIBTYPE=SCSI SHARED=YES AUTOLABEL=NO RESETDRIVE=YES


On TSM Server, we have old LTO1 tapes as as below although from Specialist
we see "L1" at the end of it:
A00001
A00002
...........

Yesterday when I used the command to checkin new LTO3 tapes with the
command:
LABEL libv 3584_LIB search=bulk checkin=scratch labels=barcode
The new tapes were labeled as:
B00001L3
B00002L3
..............

How could this happen?

If those LTO1 tapes get expired and reclaimed, will it become 8 character or
still keeps 6 character?

Thanks in advance.
