iLO goes offline

[freebird317]

I have 70 DL 20 Gen 10 servers.  3 of them ILO is going offline but the server is not.  To get iLO back online my network guy has to shut the port down, then up to get iLO back online.  I am using shared iLO with server 2019 and the server does not go offline.

It may not be the case, but check to what switches your servers are connected to. Do you have any VLAN for servers? Are they connected to the same switch as iLOs? I cornered down similar problem to configuration incompatibility between iLO and switch. I donâ t say the switch is faulty or iLO is bad, they just donâ t work with each other.

Hi 

Pleaser refer below HPE article of HPE Integrated Lights Out (iLO 5) for Gen10 Servers - Configuring iLO Network Settings and verify your server iLO network configuration.

I've seen shared iLOs on DL20 Gen 9 disappearing after XCP-ng/XenServer (Cent OS based) was booted. There it seems like a driver problem.
