499.0. "After VAXCLUSIO01_062 - %MOUNT-F-CONFQUAL" by CHEFS::HATT (Wait a minute you're not Miss Jackson......!) Mon Apr 21 1997 08:52

Hi,
      We have just installed patch VAXCLUSIO01_062. When trying to mount a tape
with MOUNT/WRITE/FOR/NOHDR3/BLOCKSIZE=8650/DENSITY=1600/OVERRIDE=EXPRIATION MUA4
we get a %MOUNT-F-CONFQUAL, conflicting qualifiers error. This mount command
worked ok before.
      And if I try MOUNT/BLOCKSIZE=8650/DENSITY=1600 MUA4: SW1959 I get
%MOUNT-F-ILLQUAL, invalid qualifier.

      Has anyone else had this? Would I need to restore back to pre-patch or
could I just change a couple of the new images?

499.1VMSSG::FRIEDRICHSAsk me about Young EaglesMon Apr 21 1997 12:1513
    /DENSITY used to be ignored for Files-11 (non-/Foreign) MOUNTS.  This
    is enforced in the new MOUNT (COMPAT, CLUSIO, V7.1 kits).  
    
    The conflicting qualifiers are /NOHDR3 and /FOR.   NOHDR3 doesn't
    make much sense to a foreign tape.
    
    The commands (and procedures) should be modified to use the correct 
    syntax.  The V7.1 doc set provides full documentation about the new
    MOUNT.
    
    Cheers,
    jeff
499.2why did mount forfeit compatibility?CUJO::SAMPSONMon Apr 21 1997 23:5715
	These V7.1 (and V6.2 compatibilty kit ECO) MOUNT changes sure
have caused a lot of trouble for customers.  In the past, OpenVMS went
to great lengths to preserve compatible behavior with previous versions.
Couldn't these more stringent checks have produced warning or informational
messages, without having to be fatal to the MOUNT operation?  Something
like:

%MOUNT-W-CONFQUAL, /HDR3 ignored; conflicts with /FOREIGN

or:

%MOUNT-W-BUFTOOBIG, !AZ buffer size !UW should be !UW or less

	FWIW,

499.3New MOUNT -- Fixes A Nest Of Support Problems...XDELTA::HOFFMANSteve, OpenVMS EngineeringTue Apr 22 1997 10:568

   MOUNT was redesigned and rewritten in V7.1 (and then back-ported to V6.2)
   to resolve a large number of MOUNT-related problems.  As Andy G. put it,
   some "collateral damage" is expected.  The MOUNT changes were tested, but
   cases where customers use the code in unforseen ways will slip through.
