9.5 Is there a "node ID" on 700s?

Yes. Most licensing systems (FLEXlm and NetLS, for example), are driven from
the LLA, available from /etc/lanscan or /usr/etc/netls/ls_targetid. There is
also a CPU ID number that HP uses for /etc/update; it may be a transformation
of the LLA, but this is not guaranteed to remain the case, and may be
disturbed by replacement of the LAN board. Additionally, the LLA can be reset
by a CE using the proper secret magic program.
