open-iscsi & iscsitarget no auto login

[Norguhtar]

Hello. I'm install iscsitarget & open-iscsi on my Gentoo Linux box. All
work fine but... I'f i'm not run
scsiadm -m node -r 7fdb81 -l after run iscsid. I'm don't get my iSCSI
storage. Why automatic not work?

My setting. What's wrong ?

If you look with dmesg you probably see the new scsi disk (/dev/sda or
similar).
Then you have to partition it with fdisk and create a filesystem on it
(mkfs - ext3 /dev/sda1 for partition one).

Nou you can mount the disk:

mount /dev/sda1 /mnt/mydisk

Automatic in this case will not mount the disc automatically, that's a
bit more complicated. Automatic only means that when starting
open-iscsi it will log in automatically into the target. Which means
the target have to be started before the initiator.

After run iscsid I'm go in dmesg only:
iscsi: registered transport (tcp)

If i'm run:
iscsiadm -m node -r 7fdb81 -l

i'm got in dmesg:

But i'm think it's shuld doing automatic.

[Albert Pauw]

Ah I see, well only the start/stop script for RedHat/Fedora and SuSE
use the automatic setting.

There is a start/stop script for Debian, which is close to Gentoo, but
it doesn't use the automatic setting. Anyway, even if a target is
logged in automatically it isn't mounted automatically (yet).

Target not logged automatic. :( About mount i'm know.

[Albert Pauw]

If you want, you can change the startup script for your Gentoo using
the part which looks for automatic setting in the RedHat or SuSE
script. You can find them in etc/initd of the open-iscsi distribution.

It is actually this bit:

TARGETS=`$ISCSIADM -m node 2> /dev/null | sed 's@\[\(.*\)\]
.*@\1@g'`
for rec in $TARGETS
do
STARTUP=`$ISCSIADM -m node -r $rec | grep
"node.conn\[0\].startu
p" | cut -d' ' -f3`
if [ $STARTUP = "automatic" ]
then
$ISCSIADM -m node -r $rec -l
fi
done

where $ISCSIADM is /usr/sbin/iscsiadm

P.S. Sorry about the terrible break ups in the lines. Just copy the bit
from the originals.

It's already enable. Read first post. Okey i'm repeat. iscsd not read
iscsid.conf & databases at start. It read this when i'm run iscsiadm -m
node -r [recordid] -l.
