I retried using two Dell C6415 nodes connected to an infiniband switch.
“Secure Virtual Machine Mode” is enabled in the bios of both nodes.
Still I never get the “Press P” option
When using the switch, one of the nodes has as last output:
Configuring backplane.. OK (ID: 1)
And the other one has:
Configuring backplane.. OK (ID: 5)
If I make a direct link between the infiniband cards, both backplanes go to ID: 1
Either way, the option to set a board as primary never appears.
Am I missing something? Do I need to connect the nodes via ethernet as well?
