discovering server when ICMP being blocked

richard wallis — Thu, 15 Feb 2007 08:26:35 GMT

Hi there, I am wanting to discover a server but the remote network has ICMP packets being dropped. I can manually add the IP and configure the SNMP but no details about the server appear (see screenshot). Insight shows the server with a red circle with a cross inside. I need to be able to poll this server for hardware failures, how do I go about achieving this under these circumstances?

How can HPSIM report on it if it cannot get to it.
It needs ping or snmp or some protocol to be able to determine if the device is actually there.
Ping timeouts can be increased if it's just a latency issue.
Also hardware failures come from the remote server via agents sending snmp traps to the HPSIM Server, not by HPSIM polling.

ICMP should only affect the automatic discovery using IP range pinging (and HP SIM has the option to query TCP/IP port 80 instead). A manual discovery doesn't require that. Since the result is an 'unmanaged' condition, HP SIM is unable to communicate with a management protocol such as SNMP. Make sure that ports required by HP SIM are open and available (from 'Understanding HP SIM Security' at http://www.hp.com/go/hpsim --> Information Library)

I can poll the server fine with GETIF using the servers community string, which is replicated in the servers details in HPSIM.
