I'm confused (nothing new there)...  You twice refer to this tape as a
"dump tape", yet you also write that it "was created with SYSDUMP".  Is
this tape a (main + virtual) memory dump of a system following a system
failure?  If so, it would be created with (control-B) DUMP, not :SYSDUMP.
Such a tape would not have a STORE/RESTORE label, therefore RESTORE will
reject it (note, the STORE/RESTORE label is *not* a volume label in the
labeled tape sense of the word).  Such a tape would have to be analyzed
by IDAT, or a similar dump analyzer.
 
If the tape was truly created with :SYSDUMP, then, as others have
indicated, RESTORE should be able to deal with it.
 
Hope this helps.
