5  PROBLEMS ADDRESSED IN VAXMOUN01_073 KIT


      o  A SET VOLUME/REBUILD command on a volume set may not reset  the
         volume  write  count  to  the  correct number of writers in the
         cluster.  This can occur when a node that had  the  volume  set
         mounted did not update the volume write count on dismount or on
         a crash.  A  SHOW  DEVICE/REBUILD  command  always  shows  this
         volume  as  needing a rebuild.  Even a SET VOLUME/REBUILD=FORCE
         command will not clear this rebuild status.

         Images Affected:

          -  [SYSLIB]MOUNTSHR.EXE

          -  [SYSEXE]SET.EXE


      o  MOUNT and Mount Verification sanity checks have been relaxed to
         correct the following issues:

          o  A MOUNT/NOWRITE command on a disk on one cluster  will  now
             work  correctly  even  if the disk is mounted with a /WRITE
             qualifier on another  cluster  in  the  SAN  (Storage  Area
             Network).   Previously, depending on the order in which the
             mounts were executed, the mount would fail with  the  error
             message:

             DIFVOLMNT - different volume already mounted on this
                         device.
