TITLE: OpenVMS VMS721H1_F11X-V0200 Alpha V7.2-1H1 F11BXQP ECO Summary
 
Modification Date: 29-APR-2002
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.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.

ECO KIT SUMMARY:

An ECO kit exists for the F11BXQP on OpenVMS Alpha V7.2-1H1. This kit
addresses the following problems:

PROBLEMS ADDRESSED IN VMS721H1_F11X-V0200 KIT:

  o A synchronization issue between RMS's read of directory files
     for wildcard operations and concurrent XQP activity has been
     identified and corrected. Prior to this change, it was
     possible that RMS could obtain an inconsistent view of a
     directory file when reading it into its internal cache. This
     could result in spurious RMS-E-FNF (file not found) errors. A
     synchronization mechanism has been implemented between the XQP
     and RMS in order to ensure that a consistent view of a
     directory is achieved.

     In order to get this complete fix, you also need to install
     the VMS721H1_RMS-V0700 ECO kit.

          Images Affected: [SYS$LDR]F11BXQP.EXE

  o The system can crash with a "MAPCNTZER, Attempted to generate
     zero length map pointer" bugcheck.

  o On Multi-Path devices, a MONITOR DISK/ITEM=QUEUE_LENGTh
     command will show a high queue length. It will stay high
     until reboot. The queue length on a switched path device, as
     seen from SDA, will show as negative.

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 VMS721H1_F11X /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 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
     VMS721H1_F11X-V0200 kit would be:

          $
          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $ DEFINE/SYS NO_ASK$REBOOT TRUE
          $!
          $ PROD INSTALL VMS721H1_F11X/PROD=DEC/BASE=AXPVMS/VER=V2.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $ DEASSIGN/SYS NO_ASK$REBOOT
          $!
          $ exit
