fencing with one APC Switch Rack PDU - node with redundant power supply

[whitewater]

Hello,
My production proxmox cluster have 3 nodes. 2 for VM with redundant power supply and 1 node for HA (arbitrary node).


I have an APC Switch Rack PDU AP7921. And only one.
I had tested it with another cluster with 3 nodes, both simple power supply.
It's work


Now, with this test cluster, il would like to test poweroff two ports, like production environment.
But i haven't success.


i have see those links :
http://pve.proxmox.com/wiki/Fencing#Dual_path.2C_redundant_power


https://fedorahosted.org/cluster/wiki/FAQ/Fencing#fence_redundant_pwr


here my cluster.conf

<?xml version="1.0"?><cluster name="test-cluster" config_version="36">
   <fencedevices>
   <fencedevice agent="fence_apc" ipaddr="192.168.10.15" login="apc" name="apc" passwd="XXX" power_wait="10"/>
   </fencedevices>

        <device name="apc" action="on" port="7"/>
        <device name="apc" action="on" port="8"/>
      </method>
    </fence>
</clusternode>
<clusternode name="proxmox-test03" votes="1" nodeid="3"/>
</clusternodes>




</cluster>

i fencing proxmox-test02 for test two port fencing (on port 7 and 8) :

oot@proxmox-test03:~# ccs_config_validate -v -f /etc/pve/cluster.conf.newCreating temporary file: /tmp/tmp.OU4PhSxsj5
Config interface set to:
Configuration stored in temporary file
Updating relaxng schema
Validating..
Configuration validates
Validation completed
root@proxmox-test03:~# fence_node proxmox-test02
fence proxmox-test02 failed

If i try this,

       <method name="dual-apc">    
                 <device name="apc" action="off" port="7"/>
                 <device name="apc" action="on" port="7"/>
      </method>

or

        <device name="apc" action="off" port="7"/>

both failed.


i have tested this :

        <device name="apc" port="7" secure="on"/>
       <device name="apc" port="8" secure="on"/>

Fencing is success for the command, but there is alway one power supply active. So, fencing don't work.
Also with bigger power_wait, like 30 or 60.


so i think action="off" and action="on" aren't recognized.


What should i do ?
Thanks.

I found a solution. Write the two ports on the same line. Example :

      <device name="apc" port="7,8" secure="on"/>

Like this, the APC PDU switch off and switch on port 7 and port 8 simultaneously
Now, i must playing to have a better time, between switch off and switch on.


One question :
someone know the difference between switch="1" and port="1" in cluster.conf parameters ?
thank you
