As far as I understand the question is "what is the difference between SMF ID and SYSNAME". Or rather "Why on Earth have two identifiers, while there is always 1:1 correlation".
I agree, I see no reason to have SMF ID and sysname independent.
Among meny identifiers I can explain the purpose of JES2 NODE name, MAS member name, LPAR name, TCPIP hostname, sysplex name, etc.
However I would like to know the reason if it exist.

I’m doing some research involving historical SMF data.  It’s caused me to wonder how 
engineers use the &SYSNAME, &LPARNAME and &SMFID symbols.  From what I can see 
is that in most instances they are the same.  LPARNAME appears to me to have little value 
in that if may or may not have an affinity for a z/OS guest in terms of naming.

&SMFID and &SYSNAME seem to generally correlate.  I’m curious if there are use 
cases where these are different and what the purpose might be?

Appreciate any insight  / best parties that people are using.
