The installation of Opene-dss has been published in previous post. Kindly refer:

Creation of iSCSI Volume:

I have assigned 1*5GB lun from VMware on Opene-dss VM. Login to opene-dss via GUI.

Go to configuration -> Volume Manager -> Volume Group

Now tick the disk (one 5 GB which I have allocated to the VM) and created a Volume Group named “yogeshvg”. The disk will be formatted by the software and will be ready for use.

Now click on the link “create a logical volume on this volume group” and select “new iscsi volume”. I am creating one .93Gb Lun to show you how to create SCSI-3 reservation Luns and assign them to target clients.

Select new iSCSI Volume -> Just Create Volume and Size of Volume -> Press Apply

Now we will create iSCSI targets, go to CONFIGURATION -> iSCSI target manager -> Targets

Press Apply:

Press the link generated “Add Logical Volume to the new target” and then attach the target:

Now install the okg on target machine where you want to present the LUN’s

Pkg installation: rpm –ivh iscsi-initiator-utils-6.2.0.873-2.el6.x86_64.rpm

[root@linux2 ~]# iscsiadm -m discovery -t st -p 192.168.74.138
