A Volume is created from a disk with a SCSI identifier that is visible by all the hosts associated with an Image Storage. These disks can be, for instance, physical SAS disks or iSCSI targets. SAS disks are autodetected during boot. iSCSI targets must be first configured with the iscsiadm tool:

~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.1
Starting iscsid: [ OK ]
192.168.1.1:3260,1 iqn.2015-06.com.example.test:target1
~]# iscsiadm -m node -T iqn.2015-06.com.example:target1 --login
Logging in to [iface: default, target: iqn.2015-06.com.example:target1, portal: 192.168.1.1,3260] (multiple)

In order to discover and configure the different types of shared storage that can be made available in a flexVDI cluster, read the Red Hat storage management documentation.
