Installation guide

Unfencing unfence
section of the
cluster
configuration
file
When enabled, this ensures that a fenced node is not re-enabled
until the node has been rebooted. This is necessary for non-
power fence methods (that is, SAN/storage fencing). When you
configure a device that requires unfencing, the cluster must first
be stopped and the full configuration including devices and
unfencing must be added before the cluster is started. For more
information about unfencing a node, refer to the fence_no d e(8)
man page. For information about configuring unfencing in the
cluster configuration file, refer to Section 7.3, “ Configuring
Fencing” . For information about configuring unfencing with the
ccs command, refer to Section 5.7.2, “ Configuring a Single
Storage-Based Fence Device for a Node” .
