Re: Service Guard 11.18

Can you clarify what it is you wish to do?
Are you looking to remove 2 nodes from the cluster?
or change a package to only fail between two nodes?
And is this permanent? or just temporary?

4 nodes? looks more like 6 nodes!
Anyway, changing the configuration for this package you need to modify the package configuration file to remove the non-required host names:
priority NO_PRIORITY
local_lan_failover_allowed YES
node_name HUG40003
node_name HUG40009
node_name HUG40015
node_name HUG40025
node_name HUG40027
node_name HUG40027

to just:
node_name HUG40009
node_name HUG40015

then run cmapplyconf -v -P

All in the Managing Serviceguard manuals
