Re: SNMP network monitoring software

[DrFranken <midrange@xxxxxxxxxxxx>]

OK Consider:

Properly connected UPS cable sends message to ALL LPARS on the system 
immediately. Said LPARs can be in any condition, including dedicated, 
and will still get UPS messages.

SNMP will require the partitions to be up and running and have the 
correct service running or they will not know the UPS has gone to 
battery or potentially low battery. If for example a switch between the 
Power Server and the SNMP device happens not to be up the UPS the system 
will never get the UPS on battery signal. This would be bad 
practice/configuration of course, but another point of failure.
