Too many LISTENER processes (11gR2 Grid Infrastructure (2 nodes))

Question

Greetings -
I get an alert that says that my LISTENER is down (EM Alert Details). It suggests a corrective action
to stop the current running LISTENER and start it again using the listener parameter (listener.ora) from
the database (RDBMS) home. There are two (2) LISTENER processes running (ps -ef | grep LISTENER) .
One process is running from the grid home and the other from the database home however only
the one running from the grid home has a listener parameter file (listener.ora) there are no others.
To confuse me even further the documentation says that I should not set the 'local_listener' parameter
and that the Oracle Agent will maintain this setting.
Any suggestions ?
Thanks in advance.
Brian

Thanks Rodrigo,
That was VERY helpful.
I disabled the old listener and then
I was able to create a new listener with the correct settings.
I can see the instances on each node using this
expression.
lsnrctl status NEW_LISTENER
However this shows on the first node that +ASM1, DM3, DM31
are available on the second node I see only +ASM2 but nothing else.
I was expecting DM3, DM32 .
Now when I first created the new listener I read that the 'local_listener'
setting need NOT be set. When I attemptied to unset that parameter then
I lost the local instances. I reset the local_listener as before
and the local instance on node one returned. Not on node two however.
My question: Do I need to set the 'local_listener' on each instance to the same
value or to different values to reflect which node they are configured for ?
I cannot see it now but I remember there is a section that references the
first node 'node_one-vip' .
Should the second node's local_listener section be 'node_two-vip' ?
Now if it need not be set this then something else has to occur to make it work.
Sorry for not being more brief,
Brian
