Double check the IP address on the BMC - if it's the same as the RMM3, you can get those weird timeouts after DHCP leases expire.
We don't use DHCP
Good thinking! Might want to double check the IP address on the BMC, anyway.
Was there any particular error when trying to access via web browser ? Is LAN channel 1 configured for an IP as well as the RMM3 NIC (LAN channel 3) ? If yes, then they cannot sit on the same subnet. Either place them separately or unconfigure LAN channel 1. Goodluck.
I've got nearly the same problem. I bought an Intel S5520HC mainboard and a RMM3.
The RMM3 is unreachable after about 24h via web browser (http and https). But it is possible to ping it.
Only a reboot solves the problem.
We are using ESX server on the machine, so there is no fixed IP assigned to the LAN channels 1 and 2.
In addition (if the esx consoles IP is important), the RMM3 is on another subnet.
BMC and BIOS were updated before the RMM3 was plugged into the system. But there is no own IP for the BMC configured.
Can someone help me?
Thanks in advance!
kind regards Tobi
The RMM3 has a different MAC address and IP address than OS and BMC LAN channel 1. You can view/modify it in BIOS. Also, you may want to apply BMC firmware again because it will also update the RMM3 firmware.
I had the problem with the different firmware versions.
So I flashed the RMM again, but the module is again not reachable after about a day.
The BMC on channel 1 is not configured.
The host system is an ESX server with the kernel IP 10.1.2.1
The RMM has the IP 10.0.1.9
Where is my mistake?
Thanks a lot!
What's your BMC firmware version? Do you get response from ping? Is there any firewall between the RMM3 and your client? Did you try a direct connection to the RMM3?
Thanks for your Answer!
The BMC firmware version is the newest one (0053, I think), which I got over an online update with the boot cd.
Yes, I get a ping response.
No, there are no firewalls.
No, I didn't try a direct connection, because:
a) ping is possible, so the connection is possible.
b) after powering down the server, unplugging it and rebooting it, the RMM works fine for about one day.
If SSH works, and the web connection fails, the only other thing I can think of is to run a network trace. See what packets are going out, and what's coming back. That will at least narrow it down to an issue on the client side, or the RMM side.
What program can I use to make the trace test?
I tried wireshark and found out that the browser sends a request but gets no answer from the RMM.
So is there anything else to test or should I replace the module on a garanty exchange?
