Hello !

We have 3590E models. I do now migration of data from old cartridges
3490 to new 3590. I have on one 3590 cartridge yet 12 GB of data writted
and ADSM is still writing to this tape. On indicator on 3590 user panel
is displayed, that cartridge is about 65% full.

When on cartridge was 9 GB of data, ADSM server was indicationg, that
cartrtridge is 100% full, but is writing data still ti the same
cartridge.

We have 3.1.2.20 Release of ADSM server. IBM done releasing of Release
3.1.2.40 ? I don't know this.

And I have yet one problem. Now I do migrating from 3490 cartridges to
3590. But database of ADSM server is rapidly growthing. From 700 MB by
Version 2.0 to 2 GB by Version 3.1.2.20. But data bulk is the same, how
in Version 2.0. Why database is so rapidly growthing ?
