Configuring Open-E DSS for SCSI-3 Persistent LUN’s
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
