ILO unreachable

Hello all. This is the situation. Yesterday, all the ILO processors have lost connection. I can't see them from System Insight Manager. I have these logs: System is unreachable.
I think it's a communication problem...
Somebody knows which ports does ILO use to communicate with SIM server?... I think the Network Admin has blocked some ports...
Thanks

Re: ILO unreachable

I believe they use standard port 80 to communicate with SIMS. Did their IP addresses change, and are those addresses in the SIMS discovery range?

Re: ILO unreachable

Part of the problem was solved... I have two NICs in the SIM server working as a team. When I force failover (disconnect a NIC), I can reach the managed servers. When I connect the NIC again, something occurs and servers turns unreachables. The Network Administrator is working on the problem. At this moment, I have the NIC disconnected and SIM is working well

Refer to the white paper titled "Managing HP servers through firewalls with HP Systems Insight Manager".

If SNMP PASS THROUGH is not enabled in iLO ,please try enabling SNMP PASS THROUGH in iLO as under
1.Logon to iLO Browser Interface.
2.Click on "Administration->SNMP/Insight Manager Settings".
3.Enable SNMP pass through.


SNMP Passthrough can also be enabled RIBCL command "MOD_SNMP_IM_SETTINGS" and also via DMTF SMASH commands
which is accessible via SSH interface.

Re: ILO unreachable

Just to reply on this... the NIC teaming was also an issue for me (Ironically also HP software)

Once I unplugged one cable SIM was able to reach the ilo cards
