Hi,

In last few weeks there were a lot of internal changed in source code of 
fence agents to make code more readable, clean and adaptable. In order 
to clean up code a bit more and remove historical burden, we would like 
to remove/replace some options (details are in 7 patches at cluster-devel).

These changes will be part of next major version of fence agents. There 
will be at least one upstream release (3.1.12) without these changes.

Brief overview:

* most of the fence agents:
     * removed option -T / test (command line / STDIN) --> you can use 
-o monitor / action to test if fence device is working
     * removed option -q / quiet --> fence agents are quiet enough by 
default
     * replaced --udpport / udpport --> use --ipport / ipport
     * on STDIN we also supported these options (this transition was 
done automatically in code) which are now replaced
         blade -> port
         option -> action
         fm -> port
         hostname -> ippaddr

* (fence_drac5) removed  -m / modulename / module_name --> replaced by 
standard -n / --plug / port
     this affect only Dell Drac CMC as other Drac devices do not use 
machine specification at all
* (fence_lpar) removed -n / partition --> replaced by standard -n / 
--plug / port

* (fence_rsb) removed -n / telnet_port --> replaced by --ipport / ipport

m,
