I want to setup iSCSI as I am running short of Shared Storage.

In one of the Doc
http://mail.digicola.com/wiki/index.php?title=User:Martin:iSCSI it says
that :


Install the Target 

1. Install RHEL4, I used kickstart with just "@ base" for packages.
Configure the system with two drives sda and sdb or create two logical
volumes(lvm). The first disk is for the OS and the second for the iSCSI



My Hard Disk Partition says:



[root at bl04mpdsk ~]# fdisk -l


Disk /dev/sda: 80.0 GB, 80026361856 bytes

255 heads, 63 sectors/track, 9729 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Since I need to make entry on:


iscsi target configuration 
Target iqn.2000-12.com.digicola:storage.lun1
        IncomingUser gfs secretsecret
        Lun 0 Path=/dev/sdb,Type=fileio
        Alias iDISK0
        #MaxConnections  6
In /etc/ietd.conf
Should I need to make separate partition or mention ??? under Lun 0
