[Linux-HA] HA configuration problems

I am fairly new to Linux, specifically RedHat Enterprise.
The project I have now is unraveling how 2 servers were setup with HA, why
it is working (but not entirely), and how to get it configured correctly.
I have read over the documentation at http://www.linux-ha.org/doc/
Currently I know there are 2 servers, both have HA setup and if one server
fails it will switch over to the 2nd server with only 1 problem. MySQL
fails to "always" load. The MySQL database is located on a SAN.
When I do: /etc/init.d/heartbeat status it says "heartbeat is stopped. No
When I do: rpm -q heartbeat -d it says "package heartbeat is not installed".
If that is the case on both servers, how is it that it is working and that
it switches over to the 2nd machine?
Is there any other method that would be used? If so, how can I find out
what/where this is?
If it is using heartbeat, what am I missing?
THEN, on the MySQL part, what process or script runs to restart MySQL and
attach it to the SAN where the DB is located?
I really appreciate any help.
