OpenVMS VMS731_SHADOWING-V0100 Alpha V7.3-1 ECO Summary
TITLE: OpenVMS VMS731_SHADOWING-V0100 Alpha V7.3-1 ECO Summary
 
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.pcsi-dcx_axpexe or
       kitname.pcsi-dcx_vaxexe, then it can be expanded by typing
       RUN kitname.pcsi-dcx_axpexe or kitname.pcsi-dcx_vaxexe.  The
       resultant file will be the PCSI installation file which can be
       used to install the ECO.

PROBLEMS ADDRESSED IN THIS KIT

New problems addressed in the VMS731_SHADOWING-V0100 kit

     o  Shadowset Aborts after node is shutdown

        Shadowsets on the remaining node of a multi-site cluster
        abort after the serving node of one member is shutdown.

        Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE




     o  Host Based Volume Shadowing (HBVS) Mini Copy Problem

        When using HBVS, if Mini Copy is used to return a former
        Shadow Set Member (SSM) to a virtual unit, and that SSM
        is removed from the shadow set before the copy can
        complete, the user must execute the following commands
        before adding that SSM is added back into the shadow set:

                 $ SHOW DEVICE/BITMAP/FULL DSAnnnn:
                 $ DELETE /BITMAP x

       "DSAnnnn:" is the virtual unit and "x" is the BitMap ID
        displayed by the SHOW DEVICE/BITMAP/FULL command.  If
        multiple BitMap IDs are displayed, delete the one that
        has the SSM in the Bitmap Name portion of the display.
        If these steps are not taken, data integrity could be
        affected.

        Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE



     o  Repair read bias calculation for multipath devices

        The read performance for a multiple member shadow set,
        that has multipath enabled members, has been using only
        the primary UCB, not the current UCB.

        Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE


     o  Default read cost for locally remote device set to high

        Default read cost for locally remote device is set to
        high.

       Images Affected: [SYS$LDR]SYS$SHDRIVER.EXE



     o  INVEXCPTN Crash during shadow copy

        When doing a Controller Assisted Copy, available with HSC
        and HSJ controllers, if the source member gets an error
        an incorrect index is set up that results in a crash.

INSTALLATION INSTRUCTIONS:


INSTALLATION NOTES:

     Reboot Required.  HP strongly recommends that a reboot is performed
     immediately after kit installation to avoid system instability.

     If you have other nodes in your OpenVMS cluster, they must also  be
     rebooted  in  order  to make use of the new image(s).  If it is not
     possible or convenient to reboot the entire cluster at this time, a
     rolling re-boot may be performed.

Installation Command

     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 VMS731_SHADOWING /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


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:

      -  $ DEFINE/SYS NO_ASK$BACKUP TRUE

      -  $ DEFINE/SYS NO_ASK$REBOOT TRUE

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

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


      -  De-assign the logicals assigned

     For example, a sample command file to install the VMS731_SHADOWING
     kit would be:

     $
     $ DEFINE/SYS NO_ASK$BACKUP TRUE
     $ DEFINE/SYS NO_ASK$REBOOT TRUE
     $!
     $ PROD INSTALL VMS731_SHADOWING/PROD=DEC/BASE=AXPVMS/VER=V1.0
     $!
     $ DEASSIGN/SYS NO_ASK$BACKUP
     $ DEASSIGN/SYS NO_ASK$REBOOT
     $!
     $ exit
