I've been lurking on this discussion, and just checked to see what we've got --
nbroot or genesis -- and we have both of them.
I had given up on node discovery years ago, we originally used the switch port
numbers and forwarding tables to assign node names. Now I use ASU to collect
the macs, and populate the mac table with a bit of grep and awk. But last week
we powered on a rack of 20 non-ibm nodes, and I was wishing we had something
easier since ASU didn't work for them.
So I have two questions --
1) Can I safely delete the xCAT-nbroot-core* RPMS ?
2) What is the current best practice method? What about for non-ibm hardware?
No, three questions
3) How do you get IBM manufacturing to use a specific different 172.29.X for
each rack they build for you?
We've had three racks arrive in different months all with 172.29.101 addresses
for the IMM, and I have to spend 5-10 minutes reprogramming each one. I can't
put them on the same network until the conflicts are gone.
What's hard for me is that we get new nodes only a couple times a year, and I
forget everything in between.
Thanks,
