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 :
[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 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

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]
