HP Services Software Patches - vaxdriv04_070
    NOTE:  An OpenVMS saveset or PCSI installation file is stored
           on the Internet in a self-expanding compressed file.
           The name of the compressed file will be kit_name-dcx_vaxexe
           for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.

           Once the file is copied to your system, it can be expanded
           by typing RUN compressed_file.  The resultant file will
           be the OpenVMS saveset or PCSI installation file which
           can be used to install the ECO.

         Installation Rating:  3 - To be installed on all systems running
                                   the listed versions of OpenVMS which
                                   are experiencing the problems described.

         NOTE:  In order to receive the full fixes listed in this kit,
                the following remedial kits also need to be installed:

                     VAXSHAD09_U2055 on OpenVMS VAX V5.5-2 systems
                     VAXSHAD09_061 On OpenVMS VAX V6.1 systems

    NOTES:

      1.  The DUDRIVER.EXE images contained in this kit for OpenVMS
          V5.5-2 and V6.1 are more current than the DUDRIVER.EXE
          images contained in the VAXSHAD09_U2055 and VAXSHAD09_061
          ECO kits.

      2.  This kit does not and is not intended to contain any fixes
          for the DUDRIVER.EXE in OpenVMS VAX V6.0.  Please see the
          VAXSHAD04_060 ECO kit for the most current DUDRIVER.EXE
          fixes for OpenVMS VAX V6.0.

    ECO KIT SUMMARY:

    An ECO kit exists for DUDRIVER on OpenVMS VAX V5.5-2, V5.5-2H4, V5.5-2HF,
    V6.1, V6.2 and V7.0.  This kit addresses the following problems:

    Problems addressed in VAXDRIV04_070 for OpenVMS VAX V5.5-2,
       V5.5-2H4, V6.1, V6.2, V7.0:

      o  A PGFIPLHI system crash may occur when the controller is rebooted.

      o  A problem exists with HSJ/HSD30, 40 and 50 controllers where,
         after an event that initiates Mountverfication, a packet
         acknowledgment will fail to complete.  The controller will
         report that it is making progress on the command, but will
         never finish.  This causes all IO to the affected devices to
         hang.

    Problems addressed in VAXDRIV03_070:

      o  The system will get repetitive Volume Processing Messages on
         Host Based Volume Shadowing Disks.  The CDDB$W_RSTRTCNT field
         of the member devices will be incrementing as seen in the
         Reinit Count field under SDA.

    Problems addressed in VAXDRIV02_070 for OpenVMS VAX V5.5-2,
      V5.5-2H4, V5.5-2HF, V6.1, V6.2, and V7.0:

      o  A shadow set can be successfully mounted on a client.  When
         a mount of the same shadow set is tried on a local (server)
         node, it fails.

      o  A node may hang due to no quorum after losing its connection
         to the quorum disk.

      o  DUDRIVER does not log IRP information.

    Problems addressed in VAXDRIV01_070:

      o  Static load balancing does not work as it designed to.

      o  System crashes occur in DUDRIVER, usually at FUNCTION_EXIT:.
         However, the crashes may also occur in other places.

      o  The errorlog does not contain any information on the actual
         outstanding command that has timed out from a Get Command
         Status (GCS) query issued from DUDRIVER to the MSCP Server.

      o  Host Based Shadowset Virtual Units hang in MountVerification.
         All IO to the device is stalled.

    INSTALLATION NOTES:

    In order for the corrections in this kit to take effect, the system
    must be rebooted.  If the system is a member of a VMScluster, the
    entire cluster should be rebooted.
