I don't see any interleaving. I see a sequential list of SSID, file numbers
and record numbers based on your listing.  In a nsrclone session there can
only be a read on one SSID and an output of that to another tape.  This is
exactly true for cloning a "volume".  But remeber that cloning a volume
pulls the SSID list first and starts seq clocing the SSIDs.

Hey Guys,

I just wanted to add this... volume S00354 is a clone volume.

If you notice ssid 2788841986 from my previous post you see that it is
interleaved with many other cloned savesets.

This list is sorted by file and record so unless I'm confused, there is
interleaving going on.  As I showed in my last post these are not the
file and rec info from the original volumes.

Sure seems like most people believe that cloning does de-multiplex, but
from what I can tell it certainly doesn't.  Unless you clone one ssid at
a time... which would be very slow.


$ mminfo -av -r 'volume(8),ssid,cloneid,mediafile,mediarec,savetime(17)'
-q 'volume=S00354'
volume ssid          clone id file  rec  date     time
