5  PROBLEMS ADDRESSED IN ALPBACK02_062 KIT


      o  A possible system crash occurs during Host Based  RAID  Unbinds
         with  MME code enabled.  A mailbox read synchronization problem
         causes the crash.

         This problem only occurs when a host-based RAID UNBIND  command
         is done while an MME-based application is running.

         This problem may occur in several different code areas  of  the
         operating  system.  In order to eliminate all instances of this
         problem, the following remedial kits  (or  their  supersedants)
         will also need to be installed:

          o  ALPSYSA02_062

          o  ALPDISM02_062

          o  ALPINIT01_062

          o  ALPMOUN04_062

          o  ALPMTAA02_062




6  PROBLEMS ADDRESSED IN ALPBACK01_062 KIT


      o  Incremental restores may get an  INCDELERR  error  message  and
         loop  continuously  when attempting to perform a directory tree
         delete on a specific DIR filespec.  The following  text  is  an
         example of the message syntax:

         %BACKUP-E-INCDELERR, error deleting
         $4$DUA153:[GHONEY.WINDATA.NETSCAPE.CACHE]CACHE.DIR;1
         -SYSTEM-W-NOSUCHFILE, no such file


      o  A possible ACCVIO (access violation) can occur when backing  up
         volume sets, particularly individual relative volumes.

      o  A possible loss of device cacheability when volume  labels  are
         overwritten could occur.  Tape subsystems behave differently.

         Re-initializing a tape device cache value  on  volume  switches
         may  result  in  the  loss of characteristic.  The type of tape
         subsystem and it's stickiness of characteristic aggravates  the
         problem.

      o  One cannot append to a non-expired tape on saveset appends when
         using  the /EXACT_LABEL qualifier.  Tape_expiration logic has a
         check specifically for the (/EXACT_LABEL) qualifier.

      o  BACKUP may invoke a Restart operation during a network  RESTORE
         operation  when  the  link  breaks.   BACKUP  was  treating the
         network saveset read as if it were a tape device.

      o  A new qualifier was added to  invoke  pre-OpenVMS  V6.2  /SINCE
         behavior.

                                                       22 October 1998


         After enhancements to INCREMENTAL restores was  done,  feedback
         from  customers  and  Customer Support Centers (CSCs) indicated
         that not everyone was completely pleased with  the  new  /SINCE
         behavior.

      o  After  installing  ALPMOUN02_062,  BACKUP/NOASSIST  no   longer
         works.  However, BACKUP/ASSIST works fine.
