I think the SMFID is older than SYSNAME. I think SYSNAME dates from the late 80s or 90s, whereas SMFID was in the early versions of MVS. Lennie Dymoke-Bradshaw

I have always thought that it was silly to have a sysname that didn't match or in some cases is related to in any way the SMFID... but I see it alot. I would love a reason from someone that kept sysname <> smfid.
