[Pacemaker] Pacemaker fails to switch on or off PDU sockets with fence_wti

[Thibaut Pouzet]

Hi,

I am trying to configure fencing on a test platform with two nodes under 
corosync+cman+pacemaker on CentOS 6.4. Both nodes have a double power 
supply from a WTI NPS-8HD16-3. IPMI fencing works like a charm, however 
I cannot get the WTI fencing to work.

The problem is that the parameter  action="" seems to be ignored by 
pacemaker.
* This is the primitive :
primitive wti_fence02_port2_off stonith:fence_wti \
         params ipaddr="" action="off" pcmk_host_check="none" port="A2" 
pcmk_host_check="static-list" pcmk_host_list="fence02.lyra-network.com" 
login="" passwd="" shell_timeout="20" login_timeout="20"

* These are the corresponding log lines :
Jun 19 16:56:45 fence01 stonith-ng[19266]:   notice: log_operation: 
Operation 'reboot' [19953] (call 0 from crmd.19268) for host 
'fence02.lyra-network.com' with device 'wti_fence02_port2_off' returned: 
0 (OK)
Jun 19 16:56:45 fence01 stonith-ng[19266]:   notice: 
process_remote_stonith_exec: Call to wti_fence02_port2_off for 
fence02.lyra-network.com on behalf of 
crmd.19268 at fence01.lyra-network.com: passed (0)

* These are the version used :
pacemaker-1.1.8-7.el6.x86_64
corosync-1.4.1-15.el6.x86_64
cman-3.0.12.1-49.el6.x86_64
fence-agents-3.1.5-25.el6_4.2.x86_64

The same thing happens with "on" actions.

When I run fence_wti from command line, it works perfectly fine with ON 
or OFF actions ! I feel there is a workaround with something like 
pcmk_reboot_action="/ON", but I don't understand how to use this...

(FYI, I'm using fencing topology like this :
fencing_topology \
         fence01.lyra-network.com: 
wti_fence01_port1_off,wti_fence01_port5_off,wti_fence01_port5_on,wti_fence01_port1_on 
ipmi_fence01 \
         fence02.lyra-network.com: 
wti_fence02_port2_off,wti_fence02_port6_off,wti_fence02_port6_on,wti_fence02_port2_on 
ipmi_fence02 )

What is wrong here ?

Cheers,
