Subject:  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 :

[doc]

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

[/doc]

My Hard Disk Partition says:

[code]

[root@bl04mpdsk ~]# fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes

255 heads, 63 sectors/track, 9729 cylinders

Since I need to make entry on:

iscsi target configuration 

Target iqn.2000-12.com.digicola:storage.lun1
        IncomingUser gfs secretsecret
        OutgoingUser
        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]
