Hi there,


I have TSM (Version 5, Release 1, Level 5.0) installed on W2k SP4
server. Connected to it is IBM 3600-r20 library with ultrium td1 drive.

I'm having a problem which already gives me a headache. It's presented
in the activity log like this :
05/14/2004 12:50:49   ANR8337I LTO volume AA9004L1 mounted in drive

It fails after writing solid amounts of data on tape (2-20GB).

The storage pool configuration is simple :

If I backup or archive something directly to storage pool of ltoclass1
then it finishes without any erros, however the migration process always
failes. It then tries to mount another libvol and failes again... And so
on... I also successfully backed up files to tape with NTBackup. So this
happens only when I try to migrate the files :(

Does anyone have any ideas on why is this happening ? Haven't found
anything in the forums or mailing lists :(((


Grateful for any suggestions and will provide  :((((
