I'm starting to look at setting up 'propr' monitoring for my production SAP environment, and wonder if anyone else is playing with HACMP clusters

If I understand what you are getting at, you will want to setup where the
resource groups with the resource groups ID as a server.  Then you set up a
persistent IP - ( if your running HACMP 5.x this is standard)  that you use
for each LPAR.  Then in you resource startup you enable reporting ( you will
need to spoof you hostname on the reports) and in you resource shutdown
scripts disable the reporting for this resource although you may want to
send a report that you are going down to Hobbit this could be a custom
report of status on your screen. The node up and down could spawn updates
along with the hacmp.out log file or a subset.
You could also make your reporting HACMP aware and they could run all the
time but only report if they own the resource group.
You also have advance event monitoring within HACMP that could spawn a
report based on an event in real time.

I need to split the monitoring for SAP and Oracle from the monitoring of
the host it runs on -- because, in an IBM HACMP environment, the
workload can move. So the oracle tests, *some* of the disk space tests,
and *some* of the proc tests move from one box to another.

So does the primary IP address.

I need to be able to track 'colorado' the box (the hostname does NOT
move) as well as 'colorado' the IP address. 'Colorado' the address could
actually be pointing to the 'thames' or 'yukon' boxes. At which time,
'colorado' the box will be responding to the 'colorado-bt' adapter
address (if 'colorado' the box is up at all).

I can get some of what I want by running two clients, one for 'colorado'
the box, and one for 'SAP' or some other such synthetic name. The
biggest two challenges I see are splitting the OS filesystems from the
application filesystems for freespace reporting, and the shifting IP
address. I may have an 'out' on the IP address in the future, if I can
migrate to what IBM calls 'aliasing' -- where they add the running
address as a second address on the adapter and respond to both.

And to make this a bit more fun, I have THREE of these silly
environments to work with.

Henrik, is there any way to hang two different IP addresses on the same
bb-host entry such that the network connectivity test will be happy if
either one responds? They are always on the same IP network, just
different host addresses (our convention is to add 100 to the last octet
to get the boot-time address for the matching run-time address).

Is anyone else doing something silly like this?

TIA
