Appendix B. Fence Device Parameters

This appendix provides tables with parameter descriptions of fence devices.

Note

Certain fence devices have an optional Password Script parameter. The Password Script parameter allows specifying that a fence-device password is supplied from a script rather than from the Password parameter. Using the Password Script parameter supersedes the Password parameter, allowing passwords to not be visible in the cluster configuration file (/etc/cluster/cluster.conf).

Field Description
Name A name for the APC device connected to the cluster.
IP Address The IP address assigned to the device.
Login The login name used to access the device.
Password The password used to authenticate the connection to the device.
Password Script (optional) The script that supplies a password for access to the fence device. Using this supersedes the Password parameter.
