>>>> 

% cd $(pkgimmxmldir) 

 

1) Generate a config file (nodes.cfg) for a 5 node cluster:

 

% sudo ./immxml-clustersize -s 2 -p 3

>>>> 

 

That is the place in 00-readme.conf to update the example of how to generate 
imm.xml with spare SCs

Migrated from http://devel.opensaf.org/ticket/2101

This ticket and subsequent ticket 
https://sourceforge.net/p/opensaf/tickets/1170/ is to support
the following two use scenarios
a) flexible deployment based on special hardware requirements for more than two 
system controllers
b) multiple nodes failing simultaneously in a cattle-type of deployment

The following is the scope of this ticket:

It will be possible to configure nodes termed as spares (to the system 
controller group of nodes).
If one of the system controller nodes dies, another "spare" system contoller 
node (if there is any available) will be get an assignment (active / standby). 
This assignment happens without requiring the spare system controller node to 
reboot.

We can add support for configuring more than two system controllers. One node 
will get an active assignment, another node will get a standby assignment, and 
the rest of the system controller nodes will have no assignment for their 
OpenSAF 2N SUs (they will be "spares").

For locking/unlocking the middleware 2N SU, refer the patch floated for 
http://devel.opensaf.org/ticket/2023

Ticket #1170 will be supported subsequent to this ticket.
