6.6. 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
node1, showing sample output.
[root@ask-03 ~]# ccs -h node1 --lsfenceopts
fence_rps10 - RPS10 Serial Switch
fence_vixel - No description available
fence_egenera - No description available
fence_xcat - No description available
fence_na - Node Assassin
fence_apc - Fence agent for APC over telnet/ssh
fence_apc_snmp - Fence agent for APC over SNMP
fence_bladecenter - Fence agent for IBM BladeCenter
fence_bladecenter_snmp - Fence agent for IBM BladeCenter over SNMP

fence_virt - Fence agent for virtual machines
fence_vmware - Fence agent for VMware
fence_vmware_soap - Fence agent for VMware over SOAP API
fence_wti - Fence agent for WTI
fence_xvm - Fence agent for virtual machines
To print a list of the options you can specify for a particular fence type, execute the following command:
ccs -h host --lsfenceopts fence_type
For example, the following command lists the fence options for the
fence_wti fence agent.
[root@ask-03 ~]# ccs -h node1 --lsfenceopts fence_wti
fence_wti - Fence agent for WTI
