I would like to tell you about what happened using bmc-config on my
Supermicro X8DTU-F with Winbond WPCM450 BMC.

This machine has an dedicated IPMI port, but I am using a shared port to
use less switch ports.

At home I made the network settings in the bios. In the datacenter I had
to change the IP and I used bmc-config for it to do that remote. But
IPMI did not work anymore.

I could ping to the IPMI IP, and I saw the webinterface on the IPMI IP,
but every password was wrong. ipmiping gave a timeout.

After long searching I found the problem, I had to change the setttings
of Volatile_Access_Mode and Non_Volatile_Access_Mode. They where
"Disabled" and after I set them to "Always_Available" and a cold-reset
IPMI did work again. (I've also tried "Shared" but this gave an error).

Not sure how this is possible. I did read the settings from the IPMI
with:  bmc-config -o > bmc-config
And I've only changed the network settings.

I think bmc-config did read wrong values from the bmc?

When I do that now again, I get the correct values for the access modes,
but now it was configured with bmc-config.

With regards,
Paul van der Vlis.
