I'm seeing similar issues here.  The script entry doesn't seem to do
anything when checking status.

For example, we have a MySQL service defined with an IP address, a shared
SAN partition, and the /etc/init.d/mysqld script. 

The service starts up and shuts down fine when done manually via clusvcadm,
but if I kill the mysql daemon with the script or manually, the clurgmgrd
doesn't seem to care.  It just runs its status check, which does report it
as "stopped" without ever restarting the service.

Also, I've seen clurgmgrd die without logging anything anywhere.  I'll just
check the cluster and it won't be running.  All of the services stay
running, but the manager is dead.  Restarting it is problematic since it
will restart each of the services causing a brief interruption.

Anyone have any ideas on how to solve either of these two problems?  I've
been waiting to deploy the cluster we've put together until I could resolve
these two issues, but have run out of things to try.
