Installation guide

ccs -h host --rmfencedev fence_device_name

For example, to remove a fence device that you have named myfence from the cluster configuration

file on cluster node no d e1, execute the following command:

ccs -h node1 --rmfencedev myfence

If you need to modify the attributes of a fence device you have already configured, you must first

remove that fence device then add it again with the modified attributes.

Note that when you have finished configuring all of the components of your cluster, you will need to

sync the cluster configuration file to all of the nodes, as described in Section 5.15, “ Propagating the

Configuration File to the Cluster Nodes” .

5.6. List ing Fence Devices and Fence Device Opt ions

You can use the ccs command to print a list of available fence devices and to print a list of options

for each available fence type. You can also use the ccs command to print a list of fence devices

currently configured for your cluster.

To print a list of fence devices currently available for your cluster, execute the following command:

ccs -h host --lsfenceopts

For example, the following command lists the fence devices available on the cluster node no d e1,

showing sample output.
