fence_scsi
The fence agent for SCSI persistent reservations.
Note
Use of SCSI persistent reservations as a fence method is supported with the following
limitations:
As of Red Hat Enterprise Linux 5.5 and fully-updated releases of Red Hat Enterprise Linux
5.4, SCSI fencing can be used in a 2-node cluster; previous releases did not support this
feature.
When using SCSI fencing, all nodes in the cluster must register with the same devices so
that each node can remove another node's registration key from all the devices it is
registered with.
Devices used for the cluster volumes should be a complete LUN, not partitions. SCSI
persistent reservations work on an entire LUN, meaning that access is controlled to each
LUN, not individual partitions.
As of Red Hat Enterprise Linux 5.5 and fully-updated releases of Red Hat Enterprise Linux
5.4, SCSI fencing can be used in conjunction with qdisk; previous releases did not support
this feature. You cannot use fence_scsi on the LUN where qdiskd resides; it must be a
raw LUN or raw partition of a LUN.
