Hi Richard,

Thanx! 

For some reason, I'm still rather new to AIX, Smit(ty) didn't let me
change this option. Now it is set to 8.

The reason we like to see the L1/L2/L3 part of the label.

Regards,

Karel

Hi, Karel -

The IBM TotalStorage Tape Device Drivers: Programming Reference manual
defines the low-level ingredients of tape processing, and there the
volser storage field can accommodate 8 chars.

In looking at the Atape.fixlist file, I note level entry:
  9.2.9.0   Add SMIT option to set 3584 TSM barcode length for
Ultrium 1/2 media
You might look into your AIX SMIT and see if yours presents that
capability.

Note, however, that it is best to use six characters, as per the TSM
Implemenation Guide redbook:
"Although IBM Tivoli Storage Manager allows you to use a volume
  identification longer than six characters, we strongly recommend that
you use
  up to six alphanumeric characters for the label (also known as VOLSER
or
  Volume ID). This should be compatible with other ANSI styled label
systems.".
(The first 6 chars of the label are the volser/volid, the last 2 are the
media identifier, per "IBM LTO Ultrium Cartridge Label Specification",
IBM site item S7000429.)
