stonith_host directive

The stonith_host directive is used to configure Heartbeat[1]'s (release 1 only), STONITH[2] configuration. With this directive, you put all the STONITH configuration information for the devices in your cluster[3] in the ha.cf[4] file, rather than in a separate file.

You can configure multiple stonith devices using this directive. The format of the line is:

stonith_host {hostfrom} {stonith_type} {params...} 

• {hostfrom} is the machine the stonith device is attached to or * to mean it is accessible from any host.

• {stonith_type} is the type of stonith device

• {params...} are the configuration parameters this STONITH device requires.

Only one stonith_host directive can have a * for {hostfrom}.

Caveats:
If you put your stonith device access information in ha.cf[4], and you make this file publically readable, you're inviting a denial of service attack.

To get a list of valid {stonith-device-type}s, issue this command:

stonith -L

To get a list of {params...} for each type of STONITH device, issue the following command:

stonith -h

NOTE: This command is mutually exclusive with the stonith[5] directive.
