Dear list,

I also thought the name of the VTOC (well, its 3rd qualifier) didn't have 
necessarily to match the DASD volser. 
In case you copy your DASD using the Flashcopy technique with DUMPCOND, and you 
later DUMP the volume 
(for DR purposes or whatever other reason) well, it DOES matter.

If the VTOC's 3rd qualifier does not match the volser, the RESTORE will create 
a wrong volser: 

volser xxxxxx --> flash with dumpcond to Fxxxxx --> dump to tape --> full 
restore -->  volser= Fxxxxx   :-(

If the VTOC's 3rd qualifier matches the volser, the RESTORE creates the right 
volser :
 
volser xxxxxx --> flash with dumpcond to Fxxxxx --> dump to tape --> full 
restore -->  volser= xxxxxx   :-)

I found this out during our DR tests. Anyone hit this before ?
