TITLE: OpenVMS VMS73_MOUNT96-V0100 Alpha V7.3 MOUNT96 ECO Summary

New Kit Date: 15-NOV-2001
Modification Date: Not Applicable
Modification Type: New Kit
 
NOTE: An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
       be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

ECO KIT SUMMARY:

An ECO kit exists for MOUNT on OpenVMS Alpha V7.3.
This kit addresses the following problems:

PROBLEMS ADDRESSED IN VMS73_MOUNT96-V0100 KIT:

  o Roxio CD Creator V5.0 for PCs creates a disk that is not
     compliant to the ISO standard. Attempting to mount these
     disks on an OpenVMS system will crash the system with an
     SSRVEXCEPT, Unexpected system service exception bugcheck.

     Crash Dump Summary
     ------------------
     Bugcheck Type: SSRVEXCEPT,
                        Unexpected system service exception
     Current Process: DKA400CACP
     Current Image: $82$DKA0:[SYS0.SYSCOMMON.]
                        [SYSEXE]F11CACP.EXE
     Failing PC: FFFFFFFF.800ACD10 EXE$QIO_C+00170
     Failing PS: 30000000.00000001
     Module: IO_ROUTINES (Link Date/Time:
                                        29-MAR-2000 00:52:23.33)
     Offset: 0001AD10

          Images Affected: [SYSLIB]MOUNTSHR.EXE
                            [SYSEXE]VMOUNT.EXE

  o When adding a shadow set member with /POLICY=MINICOPY fails,
     the error message output is:

       -SYSTEM-F-INCSHAMEM, incompatible shadow set member
             
     This error message has been changed to the more descriptive
     message:

       -MOUNT-F-REQ_WBM_FAIL, unable to add member using minicopy

          Images Affected: [SYSLIB]MOUNTSHR.EXE
                            [SYSEXE]VMOUNT.EXE

  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.

     Note: To receive this complete change you must also install
           the VMS721_CLIUTL-V0200 ECO kit.

          Images Affected: [SYSLIB]MOUNTSHR.EXE

  o The following problems are corrected:

      - 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
         mount commands were executed, the mount would fail with
         the error message:

         DIFVOLMNT - different volume already mounted on this
                     device.
 
      - If a disk is mounted with a /WRITE qualifier on one
         cluster and a /NOWRITE qualifier on another cluster in the
         SAN, mount verification will fail with a WrongVolume
         status error on the system which had the disk mounted
         /NOWRITE. This change allows mount verification to
         complete successfully in this configuration.

     Note: To receive this complete correction you must also install
           the VMS721_SYS-V1100 and VMS721_FIBRE_SCSI-V0500 ECO
           kits.

          Images Affected: [SYSLIB]MOUNTSHR.EXE
                            [SYSEXE]VMOUNT.EXE

  o Read failures during a disk mount that were due to an
     inability to read the home block and failures that were due to
     transient errors, such as from a path switch or SCSI bus
     reset, were following the same failure path. That is, reading
     the alternate home block and if successful, mounting the disk
     as read only. However, failures due to transient errors
     should not read the alternate home block and should mount the
     disk as READ/WRITE.

     For transient error failures, this change will now cause the
     READ to be re-tried for 30 seconds (30 re-tries at one per
     second). If the READ succeeds, the disk will be mounted as
     READ/WRITE.

          Images Affected: [SYSEXE]VMOUNT.EXE
                            [SYSLIB]MOUNTSHR.EXE

INSTALLATION NOTES:

No reboot is necessary after successful installation of the kit.

Install this kit with the POLYCENTER Software installation utility
by logging into the SYSTEM account, and typing the following at the
DCL prompt:

     PRODUCT INSTALL VMS73_MOUNT96 /SOURCE=[location of Kit]

The kit location may be a tape drive, CD, or a disk directory that
contains the kit.

Additional help on installing PCSI kits can be found by typing
HELP PRODUCT INSTALL at the system prompt

SPECIAL INSTALLATION INSTRUCTIONS:

  o Image Installation

     If you have other nodes in your VMScluster, an INSTALL/REPLACE
     command will need to be issued on each node in order to make
     use of the images in this kit. The commands needed are:

     INSTALL/REPLACE SYS$SHARE:MOUNTSHR.EXE/SHARE/OPEN/HEADER/PROT

     INSTALL REPLACE SYS$SYSTEM:VMOUNT.EXE

  o Scripting of Answers to Installation Questions

     During installation, this kit will ask and require user
     response to several questions. If you wish to automate the
     installation of this kit and avoid having to provide responses
     to these questions, you must create a DCL command procedure
     that includes the following definitions and commands:

       1. Define logical NO_ASK$BACKUP as TRUE

       2. Define logical NO_ASK$REBOOT as TRUE

       3. Add the following qualifiers to the PRODUCT INSTALL
           command and add that command to the DCL procedure.

           /PROD=DEC/BASE=AXPVMS/VER=V1.0

       4. De-assign the logicals assigned

     For example, a sample command file to install the
     VMS73_MOUNT96-V0100 kit would be:

          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $!
          $ PROD INSTALL VMS73_MOUNT96/PROD=DEC/BASE=AXPVMS/VER=V1.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $ exit
