I'm installing open-iscsi on a dell NX1950 w/ an MD3000. I was able to
start a target daemon as well as an initiator.
My problem is that I can't seem to find my target disks so that I can
partition them and create the file systems. Or maybe I'm not
discovering targets correctly and therefore have wrong info in /etc/
ietd.conf. Hopefully the info below will help.
$ sudo /etc/init.d/ietd start

The Dell NS1950 has two SAS disks, sda, sda1, sda2, sda3, etc... and
sdb. There are about 10 disks in the MD3000 cabinet I'm trying to
reach but don't know how to get to. I think once I know the /dev/xxx
path, I could then put that into the ietd.conf file as targets and my
iscsiadm discovery would then find them.
In /etc/ietd.conf I have the following path
Lun 0 Path=/dev/sdc,Type=fileio
Can anyone offer help here?
