RHEV Hypervisor does not automatically detect iSCSI volume after reboot in Red Hat Enterprise Virtualization 3.4

Issue

• After a reboot of a RHEV hypervisor, the host couldn't connect/login to one of the iSCSI targets, resulting in the host being marked as non-operational because the storage domain could not be activated.

• After manually executing iscsiadm commands to discover and login to the iSCSI target/session, the storage domain was then able to be activated and the host was marked as Up;

iscsiadm -m discovery -t st -p <ip>
iscsiadm -m node -L all
