Host agent not reachable in Navisphere.

Hello,
Navisphere is showing a hosts as unmanaged due to host agent not
reacheable. For some odd reason, the host agent seems to be resolving
incorrectly. The hosts in the navisphere is referring to the private IP
address on the host. That should have been the public address. Since
private IP is only used as heartbeat adapter (cluster) for the hosts.
At the hosts, nslookup is resolving it correctly to the public IP. Yet,
when I ping the hosts locally it is pinging the private IP. This host
is part of a two node cluster and the other node seems to be fine.
Register this connection's address in DNS is "uncheck" on the private
adapter.
Has anyone encountered this type of problem before?
The storage im using is CX600.
If you know of any other good usenet groups that talks about EMC CX
series, please let me know.
Thank you much,
Gabriel

| Do you have two network cards in your host?

| Yes. There are two network cards. One is used primarily for heartbeat
on a cluster and the other adapter is for any other communcation.
Thanks,
Gabriel

| That is a known bug with the navisphere agent. Just go to
powerlink.emc.com and search the knowledge base and you will find the
fix.

| Gabriel,
Do you have the desired host and IP set in agendid.txt? Most of my
problems like this come from not having agentid.txt or agent.config
setup properly.

Hello,
Create a .txt file in the Navisphere Agent directory and name it
agentid.txt. In the file on the first line, type the fully qualified
domain name of the host that you want to display in Navisphere. On the
second line, type the IP address that you want to display in
Navisphere. Save the file and then stop and start the Agent.
