SUNMC 3.5 & SB100

Question

I have installed SUN MC 3.5 server and agent on a group of machines. All machine communicate just fine except for 2 SunBlade 100s. The agents are running but the server doesn't collect data. When I run a 'discovery ' on the network for those nodes it finds the machines and labels them correctly "SB100" but shows there status of DOWN.

No when you attempt to add them it "Cannot
communicate with the agent process. Please check
host/agent an retry." I can monitor via "SNMP Ping"
but that is it.This often indicates that there is a security mismatch between your Server and Agent. Basically your Agents on the Blades don't "trust" your Server enough to respond to it when you try to make a regular icon.
First, make sure that you actually have a SunMC Agent running on the Blades and not the default Solaris "snmpdx" process. A SunMC Agent will show up as an "esd - init agent -dir /var/opt/SUNWsymon -q" process.
The next thing to check is if you specified the same security "seed" value when you ran setup on the Blades. This is the secret password/string you used when setting up your SunMC Server. If you think you may have gotten it wrong, you can reset it on the Blades with these comands:
(as root)
/opt/SUNWsymon/sbin/es-stop -a
/opt/SUNWsymon/sbin/es-run base-usm-seed.sh -s [seed_from_Server] -c agent
/opt/SUNWsymon/sbin/es-start -a
If you perform these steps and wait 3 mintues and you still cannot create an icon (and you're sure you have the correct seed), then you may have an IP address mismatch. Do the Blades have dual interfaces/NICs? If so, identify the IP address for the Blade that is on the same network as your SunMC Server (i.e. "ping [blade_hostname];arp [blade_hostname]" on the Server box), then edit the /var/opt/SUNWsymon/cfg/domain-config.x file on a Blade and edit the "agent = { ... }" section to add an "agentServer" entry with the correct IP like this:
agent = {
snmpPort = "161"
agentServer = "IP_address_of_Blade"
Then perform the 3 "as root" command I listed above again, wait at least 3 minutes, and try making your icon again. Please post to the list to let us know how it works out :)
