I have a Wangtek 5150ES scsi tape drive, its mounted as
SCSI-ID 6 on my Linux system (Slackware 3.9, Kernel 2.0.27pre10. This
problem has always been here. even from slackware 3.1! so I know its
not a new problem.
When I use the rewinding Scsi /dev/st0 device I can backup to
tape fine and dandy. but if I want to ADD a new valume after that one
with /dev/nst0 all hell breaks loose! heres a small example
pinkrose:~# tar -cvf /dev/st0 /etc/lilo.conf
tar: Removing leading `/' from absolute path names in the archive
etc/lilo.conf
pinkrose:~# mt -f /dev/nst0 fsf
pinkrose:~# tar -cvf /dev/nst0 /bin/bash
tar: Removing leading `/' from absolute path names in the archive
bin/bash
st0: Error with sense data: extra data not valid Current error
st09:00: sense key Illegal Request
tar: Cannot write to /dev/nst0: I/O error
tar: Error is not recoverable: exiting now
st0: Error with sense data: extra data not valid Current error
st09:00: sense key Illegal Request
st0: Error on write filemark.
Does the Scsi st.o driver have a problem with a Wangtek 5150es
drive using more than one volume? I don't have a manual for a 5150es
so I cannot tell if this is a problem inherent with the drive or the
software itself. Could someone tell me what the story with this drive
is? It does fsf without a fit. seek and tell work from mt too. as
does rewind and retension.
Related to this. how do I physically REFORMAT Scsi tapes? I
have a few that their formats are muffed up and a mt -f /dev/st0 erase
does NOT fix. I really wish someone write a SCSI-tape-HOWTO!!
After you copy a volume to tape. how do you findout how much
ROOM is left? I had problems with multiple volume tar tapes on both my
Wangtek and my Ditto 800 (floppy based tape unit). tar reads back
first tapes dandy. its the second and third tapes that get out of sync
with first tape. Do I need to specify tape length in tar????
PLEASE HELP ME FIND THESE ANSWERS. WEB PAGES, MAILLED COPYS OF
WANGTEK MANUALS.... ANYTHING!!!!!
