OpenVMS VMS73_SHADOWING-V0200 ALPHA V7.3 SHADOWING ECO Summary
TITLE: OpenVMS VMS73_SHADOWING-V0200 ALPHA V7.3 SHADOWING ECO Summary

New Kit Date:       24-JAN-2002
Modification Date:  Not Applicable
Modification Type:  Updated Kit  Supersedes VMS73_SHADOWING-V0100
 
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, then it can
       be expanded by typing RUN kitname.pcsi-dcx_axpexe.  The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

       In order to receive all the corrections listed in this
       kit, the following remedial kits, or later, should also be installed:

         None


ECO KIT SUMMARY:

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

PROBLEMS ADDRESSED IN VMS73_SHADOWING-V0200 KIT:

  o  A system can experience many MountVerifcation  messages  occur
     with  no  apparent  cause and no errors reported.  There is no
     way to identify what is causing these messages

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


  o  In a multi-node cluster, some cluster members  may  hang  when
     accessing a shadowset if:

       o  The shadowset being accessed has multiple members.

       o  All the shadowset members are local to one of the  cluster
          nodes.

       o  All the shadowset members are  being  MSCP-served  by  the
          local node to the other cluster members.

       o  The local node goes down and remains  down  for  at  least
          MVTIMEOUT seconds.

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


  o  On multiple member shadow sets greater  than  18  Gigabyte  in
     size,  if  the  port  driver  returns  an  SS$_DATACHECK for a
     IO$_WRITEPBLK, the wrong LBNs will be written by the shadowing
     driver.  This could lead to data corruption.

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


  o  On a stand alone system,  when  a  virtual  unit  aborts,  the
     system could crash with an INVEXCEPTN bugcheck.

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


  o  OPCOM will frequently display a virtual unit  device,  or  the
     member  device string, without any other message.  This can be
     seen during startup if you are using a shadowed  system  disk,
     or  even  during  the  dismount  of  the  virtual  unit or the
     dismount of members.

     This has been  corrected  so  that  you  now  will  receive  a
     complete VMS message, such as:

     %SHADOW-I-VOLPROC, DSA719: shadow master has changed.
     Dump file WILL be written if system crashes.

     rather than just displaying:

         DSA719:

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


INSTALLATION NOTES:

This kit requires a system reboot.  Compaq 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 INSTRUCTIONS:

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_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

SPECIAL INSTALLATION INSTRUCRIONS:

  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:

        -  $ 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=V2.0

        -  De-assign the logicals assigned

     For  example,  a  sample   command   file   to   install   the
     VMS73_SHADOWING-V0200 kit would be:

          $
          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $ DEFINE/SYS NO_ASK$REBOOT TRUE
          $!
          $ PROD INSTALL VMS73_SHADOWING/PROD=DEC/BASE=AXPVMS/VER=V2.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $ DEASSIGN/SYS NO_ASK$REBOOT
          $!
          $ exit
