We have a couple of nodes with redundant power supplies and two APC

addfence to add both switches to the cluster.conf file, but is there
any way to specify both switches for each node, from the command line?
Thanks in advance.

Not that I know, but make certain that you use the 'option' attribute to
make certain both power supplies are off, before they are turned on
again. The default behavior is reboot, and it is possible for both
supplies to never be off at the same time - hence the machine is never
rebooted
In the cluster.conf file, it would look like this:
<clusternode name="node1">
<fence>
<method name="1">
<device name="my_apc" port="1" option="Off"/>
<device name="my_apc" port="2" option="Off"/>
<device name="my_apc" port="1" option="On"/>
<device name="my_apc" port="2" option="On"/>
</method>
</fence>
</clusternode>
