Appendix B. Fence Device Parameters
This appendix provides tables with parameter descriptions of fence devices.
Note
Certain fence devices have an optional parameter. The parameter allows specifying that a fence-device password is supplied from a script rather than from the parameter. Using the parameter supersedes the parameter, allowing passwords to not be visible in the cluster configuration file (
/etc/cluster/cluster.conf).
