iDrac of R430 unresponsive after server boot finished

Question

Hey Guys,

this is my first post here, so please be patient. Also english is not my mother tongue, but I try my best

What my setup is:

I'm using 2 Dell PowerEdge R430 as Firewalls running the latest pfsense (2.4.5). One of them is the master node, the other one is configured as backup and is taking over IPsec tunnels, VPN connections and the routing when master is offline.

My iDrac 8 is on version 2.70.70.70 on both machines. Both iDrac are in the same VLAN, the ports on the switch are tagged the same. Every iDrac has its own static IP address configured (no dhcp).

Now my issue:

When master is offline and backup is taking over, I have access to both of the idracs with the different IPs. When I power up the master again, while booting, idrac of master is available, also from backup. When master is taking over the full control / full firewall functionality, the idrac of master becomes unresponsible. The iDrac of backup is accessible at any time.

The connection is unresponsive via ssh and web (timeout). The leds on the switchports and on the serverports itself are blinking as intended.

what I did:

* checked Switch, no issues found

* checked cable, no issues found

* updated iDrac, because I read about a memory leak, did not help

* configured differen IP, because I thought that my minotoring would "DDOS" the interface, no luck

* changed the LOM of the idrac (from 4 to 3) no luck - failover network is setup on all loms.

What I try to plan, but didnt do until now:

* completely reset the iDrac and configure it new

I really don't know what do to anymore - someone has a hint for me? Is there a hidden setting, that locks me out?

Thanks and best regards,

Sebastian

As you are seeing the issue with shared mode, I would suggest to ensure both firmware and driver on the network controller is latest. Is iDRAC and host is on same network or different network? As you are seeing the issue when firewall is up, is it possible to stop firewall and check iDRAC connectivity.

>> As you are seeing the issue with shared mode, I would suggest to ensure both firmware and driver on the network controller is latest.

will check that, iDrac is the latest (20.70.70.70). Would you recommend disabling the "fallback network on all LOMs" option and only use the port, that as selected specifically?

>> Is iDRAC and host is on same network or different network?

I have a network on the same port as the iDRAC. This network is my management network. It is reachable without any issues, while at the same time iDRAC isn't.

The other networks are on another port on an additional network card, so this has nothing to do with the idrac port / management network.

>> As you are seeing the issue when firewall is up, is it possible to stop firewall and check iDRAC connectivity.

Yes, as I said, when Firewall (Master) is offline, and Firewall (Backup) is operating, both idracs work without any issues. If both are up, Masters iDRAC is not reachable after boot is finished.

I'm 99% sure that the issue is not an IP address conflict - that was the first thing I thought. I used multiple IPs for this iDrac and changing does not help.

But keeping the Master offline is not a fix for me.

Thank you for your reply @DELL-Shine K!

Can you check what FW and driver you have for LOM's and ensure it is latest. Some time older FW or Driver for LOM create such issue. When you said master firewall is offline are you bringing the server down(power off) or bringing the firewall service only down and server is up and running

Also let me know is there any difference between 2 server in terms of configuration and operating system installed
