linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Singh Raina, Ajeet Few issue Still prevailing: As I guess, after Setting Up iSCSI Target
and iSCSI Initiator, I am not seeing any shared on both the cluster nodes. I guess I missed few step: The DOC at end says: Voila! you should now have a new SCSI disc avaiable
for use. Now you can use fdisk to partition the disk (fdisk /dev/sdb) and use
mkfs to format the partition (which is out of the scope of this howto). Do I need to do fdisk? Pls Help. From: linux-cluster-bounces@xxxxxxxxxx

Is above Entry Correct? My machine Hostname is pe.logical.com. Little confused about storage.lun1 whats
that? I have now not included any incoming or outgoing

confusion on client side too. The Doc says You need to make Entry on

What’s the above entry means?IP?? As for My Setup I am setting up RHEL 4.0
machine with IP 10.14.236.134 as Target Machine and The two Nodes 10.14.236.106
and 10.14.236 108 as Already been in Cluster Nodes. Thanks for Helping me out. But You need to
also Help me What Entry in Cluster.conf I need to make after these things being
