Is this a problem with the Apache init script or with the rgmanager 
logic? The same thing happens no matter which service you run: vsftpd, 
sendmail (I just checked these additional two).

I haven't checked LSB (or whatever is the standard which init scripts 
need to conform to) but as far as I understand it, you will get non-zero 
exit code if you try to stop an already stopped service, which confuses 
the heck out of rgmanager and requires that you (a) start the service 
(e.g. apache) manually. (b) disable it via clusvcadm or GUI (c) enable 
it via clusvcadm or GUI.

This recovery sequence makes no sense to me (nor does rgmanager / 
clusvcadm's logic)
