I've inherited a half-installed instance of ADSM and just connected an ADIC
Scalar 1000.  As part of the installation I did a BACKUP DATABASE command
last week.  It used volume 000101 to do the backup which had been defined as
scratch.  Today I came in after a 4 day weekend and discovered that the
database doesn't get automatically backed up, so I issued the BACKUP DB
command
as shown below.  The system then proceeded to examine and reject every tape in
the system.  Why couldn't it use the same tape where the database was
originally stored?  RTFM answers welcome as long as they contain a pointer to
the FM.
