Re: [Freeipmi-users] Help | Cannot Detect Nodes with IPMI

[Jeff Van]

Hi Al,

Hmm, it seems as though I've configured everything correctly then.

I also tried checking the ARP cache like you suggested, but in the output,
there were no IP/MAC addresses that matched the IP/MAC address of the node
I am trying to communicate with. However, if my understanding of ARP is
correct, that shouldn't be unusual, since my head node has not been able to
receive any kind of communications from the node I am trying to communicate
with.

I've also checked the ipmi-oem manpage, and I wasn't able to find anything
particularly useful.

However, I noticed that when I use the command on the head node:
`sudo bmc-device --get-bmc-global-enables`, I receive the following output:

Receive Message Queue Interrupt : disabled

Event Message Buffer Full       : disabled

Event Message Buffer            : enabled

System Event Logging            : enabled

OEM 0                           : disabled

OEM 1                           : disabled

OEM 2                           : disabled

Perhaps the fact that OEM 0-2 are disabled might provide a clue as to what
my problem could be?

If you happen to have any other ideas on how I might go about debugging
this, or if there are other places to which I can direct my questions,
please let me know. Thank you again for taking the time to help me with
this!
