Successful login with iscsiadm on target still doesn't create block device
- by Halfgaar
I've set up an experiment to test iscsitarget and initiator, which at some point worked. Later, I turned the setup back on and much to my dismay, the initiator machine stopped making block devices for its successful logins. As far as I know, I haven't changed anything on either machine.
Some details:
# iscsiadm -m node --login

/var/log/syslog doesn't give errors:

lsscsi doesn't show my devices:

And there are no block devices in /dev for it:
# ls -1 /dev/sd*
/dev/sda
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sda4
I tried loading all scsi kernel modules I could find, but that doesn't seem to be the problem.
I reall don't get this; it used to work. I found people with similar problems (here and here) but no solution.
Initiator is Debian Sqeeuze (testing), target is Debian Lenny (stable). iscsitarget is 0.4.16+svn162-3.1+lenny1, open-iscsi (initiator) is 2.0.871.3-2squeeze1. Target kernel: 2.6.26-2-amd64, initiator kernel: 2.6.32-5-amd64
