Adjusting NIC settings to fix DMAR faults

Hello everyone,

I am currently facing an issue related to this HP Advisory:

This is for DL380 gen9's using ilo 4.0.

We cannot use the first option listed regarding disabling IOMMU so we are trying to figure out a method of adjusting the values for the "HP Shared Memory Features" on the NICs.

We can, of course, do this manually but we are looking for a way to automate this process since the rest of our deployment process is already automated. I have tried looking at options using RESTful API commands and  hponcfg but I have not found anything yet.

Ideally we could make these changes before we install an OS but I am interested in any ideas.

Any tips or guidance would be greatly appreciated.

Hi AStranger,

You can use the HPE Conrep Utility to copy the BIOS settings and deploy them onto other identical servers. Please refer to the below user guide:-
