Hi David,

I'm a little confused - I haven't been following this thread, but I know in my recently installed LTO3-populated 3584's (only LTO3's, not a mix of LTO2's and LTO1's) here in London, using Atape 9.3.0.5 on AIX 5.2ML04 and with TSM 5.2.4.5 I can see 6 character volsers (configurable from the physical library control panel). In fact, when I first checked tapes in, I saw 8 character volsers - after changing the setting on the library control panel, they became six characters instead (actually, I had to re-check them in though...).

Shoot me down if I'm getting the wrong end of the stick here...

[ADSM-L] LTO1, LTO2 & LTO3 tapes in 3584 library





Well, folks, I had promised an update a couple of weeks ago,
but was delayed with non TSM things here and going back and
forth with IBM/Tivoli on my PMR.  I had a hard time getting
answers, but finally got some.

As I had suspected, LTO3 volser is treated DIFFERENTLY
than LTO1/LTO2!  LTO3 ONLY uses 8 char volser on TSM,
LTO1/2 can use 6 or 8!  How about that, sports fans?

IBM Technote 1217789, just released, explains this and has a
table for LTO, 3592 and respective WORM classes, and the
TSM Server platforms showing what you get depending on
what you have.

Also I noticed with my TSM 5.2.6.0 on AIX, if you use the Web
Admin for DEF DEVCLASS or UPD DEVCLASS for LTO, the
"Recording Format" pulldown does not have Ultrium3 or ULtrium3C
as an option - bug.  If you use the  CLI, you can use those options.
(I can see Andy Raibeck smilling!).

A little more later after I do some testing.
