The target must also support the preempt-and-abort SCSI subcommand. > It really

Was actually trying to do the setup on two desktop nodes before doing it on
production . So for that , has thought of using a third node and configure one
of the partition on that node as iscsi target and share it among the cluster
nodes. Can we use fence_scsi to fence such linux based iscsi targets ?
