Hello,

I am Praveen, and new member of this community. I was working  on a perl
project related to iSCSI, so started using open-iscsi and iscsitarget to
research a bit before going on with my project.

I am using ubuntu server/client for my tests. Everything worked fine, but no
device was created on the client machine.

The steps which were taken on the server and the client machine are as below

Server
-------

r...@krystal:~# aptitude install iscsitarget

Below steps were done as the machine didn't have lvm.

r...@krystal:~# pvcreate /dev/sda9
Physical volume "/dev/sda9" successfully created

r...@krystal:~# vgcreate thomas /dev/sda9
Volume group "thomas" successfully created

r...@krystal:~# lvcreate -n datastore -L 10G /dev/mapper/thomas
Logical volume "datastore" created

The steps below were to generate iSCSI initiator

r...@krystal:~# ietadm --op new --tid=2 --params Name=iqn.192.168.1.107.
datastore

r...@krystal:~# ietadm --op new --tid=2 --params
Path=/dev/mapper/thomas-datastore,Type=blockio

r...@krystal:~# ietadm --op new --tid=2 --user --params
IncomingUser=praveen,Password=praveen

r...@krystal:~#


Client
------------

r...@spartan:~# aptitude install open-iscsi

r...@spartan:~# vi /etc/iscsi/iscsid.conf      -- > configured with help of
http://www.cyberciti.biz/faq/howto-setup-debian-ubuntu-linux-iscsi-initiator/

r...@spartan:~# iscsiadm -m discovery -t sendtargets -p 192.168.1.107
192.168.1.107:3260,1 iqn.192.168.1.107.datastore

r...@spartan:~# iscsiadm -m node --targetname iqn.192.168.1.107.datastore

After that I tested it on other 2 machines (ubuntu) that already have OS
installed in LVM as I thought the issue could related to the LVM I created
on my machine.

The steps followed were as below

Server -- 192.168.1.124
++++++++++++++++++

step 1:lvcreate -n praveen-lv -L 10G nfspool

step 2:/etc/init.d/iscsi-target start

step 3:ietadm --op new --tid=2 --params Name=iqn.192.168.1.124.praveen-lv

step 4:ietadm --op new --tid=2 --params
Path=/dev/mapper/testzx-praveen--lv,Type=blockio

step 5:ietadm --op new --tid=2 --user --params
IncomingUser=praveen,Password=praveen

Client -- 192.168.1.123
++++++++++++++++++++

step 1:vi /etc/iscsi/iscsid.conf      -- > configured with help of
http://www.cyberciti.biz/faq/howto-setup-debian-ubuntu-linux-iscsi-initiator/


step 2:/etc/init.d/open-iscsi start

step 3: iscsiadm -m discovery -t sendtargets -p 192.168.1.124
result
------

192.168.1.124:3260,1 iqn.2001-04.com.example:storage.disk2.sys1.xyz

step 4:iscsiadm -m node --targetname iqn.192.168.1.124.praveen-lv --portal
192.168.1.124:3260 --login
result

step 5:/etc/init.d/open-iscsi restart

Here too, no new device got created on the client.

Could you please guide me, on if the issue  is related to the steps I used
or if it is related some settings/software versions.
