2.2. Listing Fence Devices and Fence Device Options
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
node-01, showing sample output.
[root@ask-03 ~]# ccs -h node-01 --lsfenceopts
