Subject: [Linux-cluster] iSCSI Setup as Alternative to Shared Storage..

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 storage

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

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14        9729    78043770   8e  Linux LVM

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 path=??? Entry?

If you wish you can create a separate partition. Else create a file & give the full path of the file. [e.g path=/home/test/target_file]

Pls Help
