Hi Parvez

We use BladeCenters for our clusters, and I can confirm that the
'blade="2"' parameter will translate to 'blade[2]' on the AMM.  IOW, the
'2' is the slot number that the blade is in.

Two more things that might be of help:

- The user specified in the 'login' parameter under the fencedevice
  should be a 'Blade Administrator' for the slots in question.

- If you're running with SELinux enabled, check that the
  'fenced_can_network_connect' boolean is set to 'on'.
