Sorry Mark,
didn't really wanted to bother you, sorry to hear you were ill.
Have you been actually able to reproduce the problem?
Quite simply:
- use the targets.conf I sent earlier
- start up tgt manually, tgt -d8 -f
- tgt-admin -e -v to set up the vtl using targets.conf
- login with iscsi
- now try to get the status of the changer (mtx -f /dev/changer status)
What happened with me is that tgtd dies. I don't know if my previous
email,
regarding the malformed scsi packet, has anything to do with it. I
assume not
as when I set it all up using standard scripts it does work (with
malformed packets).
Mind you, according to wireshark the only malformed packets are when
the status
of the changer elements are send back to the initiator.
OK, looks like I'm failing step 1. :(
I created /root/btapes/notape[123] and a 'touch /root/smc' file(s).
I've not used the perl tgt-adm before..
