Hi all, Sorry about posting the HW compression version first (especially to anyone who searches the archives). I read more on st.conf (yes it's running under Solaris 8) and played some with the various options. Here is what I got when I used the correct device:
$amtapetype -e 40g -f /dev/rmt/0ln -t HP-DLT1e Estimated time to write 2 * 40960 Mbyte: 30720 sec = 8 h 32 min wrote 1232058 32Kb blocks in 94 files in 13969 seconds (short write) wrote 1238517 32Kb blocks in 189 files in 14193 seconds (short write) define tapetype HP-DLT1e { comment "just produced by tapetype prog (hardware compression off)" length 38602 mbytes filemark 0 kbytes speed 2807 kps } Now to actually try a backup.
