Does anybody has any idea what is platform agent and which of the servers would this agent. I am trying to understand the difference between an agent and a platform agent? How do I install platform agent?
Sun 3800-6900 series systems don't run Solaris on their system controllers... so you can't install a regular SunMC Agent on them. Instead you enabled an extra "platform" Agent on a different system (usually the SunMC Server) that acted as sort of a proxy for the controllers, and communicated with them using SNMP.
If you don't have one of these models in your environment, you have no need for 'platform' Agents:
zeealee - the config reader error you mentioned on the M5000 and M4000 can be avoided by installing the Mx000 Version 3 Add-On module package on your SunMC server.
the XSCF on the M-Series will also need to be configured for SunMC.. this can be done using the "setsunmc" command on the XSCF. issuing a "man setsunmc" will provide you instructions.
also - a strange requirement for SunMC on the XSCF is that a nameserver is set. this can be done with a "setnameserver"
