iSCSI is a protocol that allows you to connect to block-oriented storage over the IP-network. To have an ISCSI target, you do not need to buy an enterprise-class ISCSI storage, you can start an ISCSI target as service on your computer. This is especially useful when running e.g. cluster tests on shared storage.
QuickStart
I do have a walk around for this pblroem. i have tested it on the windows 2003 server and found to be working.Below is the steps for the walk around.1)Create a Connect_SAN.bat with following commands and put it in c:\-Diskpart /s “c:\Connect_SAN.txt”-Save file2)Create a Connect_SAN.txt with following commands and put it in c:\-Select Disk N (replace N with the disk number which is offline. You can check this in logical Disk Management)-Online-Exit-Save file3)Open the Group Policy Editor (Start > Run > enter gpedit.msc'.)4)Expand Computer Configuration'.5)Expand Windows Settings'.6)Select Scripts (Startup/Shutdown)'.7)Double-click on Startup' in right-hand panel. Click on the Add' button.9)Click on the Browse' button.10)Navigate to your batch file(Connect_SAN.bat), select it and OK your way out of the Editor.11)Close the Editor.12) Reboot System

In this chapter we will set up an iscsi target and test it by installing an iscsi initiator.
Set up a target
- Download the latest version of iscsi-target from http://iscsitarget.sourceforge.net/. In this example, we use version 0.4.15.
- Unpack the package you just downloaded
tar xvfz iscsitarget-0.4.15.tar.gz
cd iscsitarget-0.4.15 make && make install
on problems see the article Compiling.
- create a configuration for your service:
/etc/ietd.conf
Target iqn.2007-12.local.net:storage.lvm
Lun 0 Path=/dev/hdb
- start the service
/etc/init.d/iscsi-target start
- verify the service is running
$ lsof -i [...] ietd 8692 root 7u IPv6 36856 TCP *:iscsi-target (LISTEN) ietd 8692 root 8u IPv4 36857 TCP *:iscsi-target (LISTEN)
Set up an initiator
To set up an iscsi initiator, install the openiscsi package. Then, discover your targets. Let's assume the IP-address of your target is 192.168.0.5
$ iscsiadm -m discovery -t st -p 192.168.0.5 [fa084c] 192.168.0.5:3260,1 iqn.2001-04.com.example:storage.disk2.sys1.xyz [3727f9] 127.0.0.1:3260,1 iqn.2001-04.com.example:storage.disk2.sys1.xyz $ iscsiadm -m node [fa084c] 192.168.0.5:3260,1 iqn.2001-04.com.example:storage.disk2.sys1.xyz [3727f9] 127.0.0.1:3260,1 iqn.2001-04.com.example:storage.disk2.sys1.xyz
You know now you have a target named iqn.2001-04.com.example:storage.disk2.sys1.xyz Now have a look what drives you have attached:
$ hwinfo --block --short disk: /dev/sda VMware Virtual S /dev/sdb IET VIRTUAL-DISK partition: [...]
Now connect your iscsi target:
$ iscsiadm -m node -T iqn.2001-04.com.example:storage.disk2.sys1.xyz -p 192.168.0.5:3260 --login
And find a new device in your list:
$ hwinfo --block --short disk: /dev/sda VMware Virtual S /dev/sdb IET VIRTUAL-DISK /dev/sdc IET VIRTUAL-DISK partition: [...]
