On my mageia3 systems, iSCSI targets connections are not established at boot time.
Once the system is up I can establish these connections manually with the command:
iscsiadm -m node --loginall=automatic
journalctl shows me only that the open-iscsi.service has successfully started. There is no other information about any attempts to establish connections to iSCSI targets.
My workaround solution is to run iscsiadm from rc.local, and that works, but this also requires me to then restart any services that depend on filesystems on the iSCSI targets. This is bit kludgy and I'd rather have something that integrates more cleanly with the systemd start of the iSCSi service and other services.
