Even with IPMI, you still need a crash cart of some type to initially

out of the box with BIOS configured to try booting over the net before

sometimes this is conditional on the local HD having no active partition.
great: so they boot from a special PXE image I set up as a catchall.
(dhcpd lets you define a catchall for any not nodes which lack a their own
MAC-specific stanza.) when nodes are in that state, I like to
auto-configure
the cluster's knowlege of them: collect MAC, add to dhcpd.conf, etc. at
this stage, you can also use local (open) ipmi on the node itself to
configure the IPMI LAN interface:
ipmitool lan 2 set password pa55word
ipmitool lan 2 set defgw ipaddr 10.10.10.254
ipmitool lan 2 set ipsrc dhcp
none of this precludes tricks like frobing the switch to find the port-MAC
mappings of course - the point is simply that if you let unconfigured nodes
autoboot into a useful image, that image can help you automate more of the
config.
My cluster nodes' IPMI share their physical port with the primary NIC.
Before using IPMI, I had to enable it in the BIOS and then assign it an
IP address in the BIOS, too. I didn't think of using ipmitool. I wonder
if I could do all that using ipmitool, without enabling IPMI in the BIOS
first. Anyone know for sure?

With all (and various) flavors of IPMI and BMC hardware on Intel, Supermicro,
and Asus systems since about 2004, we've been able to use ipmitool or equivalent
software in Linux to setup IPMI LAN and other parameters.
Consistently, though, for systems with serial over LAN, we've always had to
configure serial port redirect settings in the BIOS. The latter is why we've
always tried to get vendors to provide a mechanism for replicating BIOS settings
from machine to machine without using a crash cart (not always successfully,
unfortunately).
