Configuring iSCSI Volume in Ubuntu/Linux

The other day i got Dell EqualLogic PS6000 Series SAN box to experiment on. 
For windows it was pretty straight forward using the iSCSI tool present in administrative tools. 
I wanted to try it on Linux so i searched a bit and at last formatted & mounted it on Ubuntu. Here are the steps that i followed.


Follow the steps to configure iSCSI volume on ubuntu (i tried on 11.10):

1) You need to install open-iscsi package :

      #sudo apt-get install open-iscsi

2) Now you need to run discovery agains t the iscsi host:

     # iscsiadm -m discovery -t sendtargets -p <iscsi server ip address>

eg: If 192.168.11.110 is the ip address of iscsi server

     # iscsiadm -m discovery -t sendtargets -p 192.168.1.110

OR

    # iscsiadm --mode discovery --type sendtargets --portal 192.168.11.110

3) Note down the record id (such as iqn.xxxxxxxxxxxxx:test) found by the discovery. You need the           

    same for login. Login, must use a node record id found by the discovery:

    # iscsiadm --mode node --targetname iqn.xxxxxxxxxxxxx:test --portal 192.168.11.110:3260 --login

4) Restart the service:

    # /etc/init.d/open-iscsi restart

5) Now you should see an additional drive on the system such as /dev/sdd. Use /var/log/messages or 

     /var/log/syslog file to find out device name: (in my case /var/log/syslog):

    # tail -f /var/log/syslog

6) If your device name is /dev/sdd, enter the following command to create a partition:

    # fdisk /dev/sdd

  

 Use the help in the fdisk menu to create a new partition.

7) format the partition:

   # mkfs.ext3 /dev/sdd1

8) Mount the file system:

    # mkdir iscsi

    # mount /dev/sdd /iscsi
