[Pacemaker] Configuration help.

[James FLatten]

I hope this mess makes sense!  My current setup looks like this:

     nodea                 nodeb
+-----------+ +-----------+
|      eth0 |---------| eth0      |
|      eht1 |---------| eth1      |
|      eth2 |--+  +---| eth2      |
|           |  |  |   |           |
|           |  +------| ilo       |
|       ilo |-----+   |           |
+-----------+         +-----------+

(bad ascii art!)

I have crossed connected the HP iLO3 interfaces and setup stonith on 
each node.  This works well but for the scenario of complete loss of a 
node.  I would like to configure the cluster so it behaves like so:

Secondary complete failure (Power completely gone)

nodea(P) --- nodeb(S)
nodea(P) --- (gone)

result: nodea remains primary, services are *not* interrupted

Primary complete failure (Power completely gone)

nodea(P) --- nodeb(S)
(gone)   --- nodeb(S)
-- administrator intervention --
(gone)   --- nodeb(P)

result: Services can be restored after admin confirms primary is indeed 
gone.

Is this possible with my setup?

Here is my current config:

Is this possible?
