I just ran amtypetype -f /dev/rmt/0bn, a Sun Storedge L9 autochanger
and recieved the following:
define tapetype unknown-tapetype {
comment "just produced by tapetype prog (hardware compression on)"
length 34169 mbytes
filemark 28 kbytes
speed 1787 kps
}
I'm confused because I believed this to be a DLT8000 drive which should
be closer to 80 MBytes compressed, and certainly the speed is not what I
expected either. I ran amtypetape -c -f /dev/rmt/0bn and amtypetape -c
-f /dev/rmt/0cbn and received nearly identical output:
amtapetype -c -f /dev/rmt/0cbn
Writing 256 Mbyte compresseable data: 27 sec
Writing 256 Mbyte uncompresseable data: 56 sec
WARNING: Tape drive has hardware compression enabled
Estimated time to write 2 * 1024 Mbyte: 448 sec = 0 h 7 min
amtapetype -c -f /dev/rmt/0bn

Host is a Sun E250, with HVDS adaptor.
Does anyone have experience with this drive?
