ECO KIT SUMMARY:

An ECO kit exists for MTDISMOUNT.EXE on OpenVMS VAX V5.0 through V6.2.
This kit addresses the following problem:

  o  A device mounted foreign may become inaccessible after a
     dismount or may appear to be allocated to a nonexistent
     process.  The system must be rebooted to regain access to the
     device.  CSCPAT_0253 corrects this problem in most cases.
     However, the problem may still occur on some systems after this
     patch kit has been installed.

     This kit provides a program called

          'CSCPAT_0245_USE_WITH_CAUTION_MTDISMOUNT.EXE'

     that will allow the user to deallocate a device allocated
     to a non-existent process.

     ************************************************************
     *                                                          *
     *                          CAUTION                         *
     *                                                          *
     * This image needs to be run from an account with CMKRNL   *
     * and WORLD privilege and should be used with extreme      *
     * caution.  A system crash and reboot may occur if         *
     * instructions are not followed carefully.                 *
     *                                                          *
     ************************************************************

To run the image, the following steps must be performed:

  1. Ensure that the device is allocated to a process that no longer
     exists on the system by using the $SHOW DEVICE/FULL and $SHOW
     PROCESS commands. If the device is not allocated or it is
     allocated to an existing process, the program will exit with
     the error message:

          %SYSTEM-F-DEVNOTDISM, device not dismounted

  2. Run the CSCPAT_0245_USE_WITH_CAUTION_MTDISMOUNT.EXE image using
     the following command:

          $ RUN SYS$MANAGER:CSCPAT_0245_USE_WITH_CAUTION_MTDISMOUNT

The program outputs the following message and prompts for the device
name to be released:

----------------------------------------------------------
MTDISMOUNT V02.02

     This program is provided by the DIGITAL Customer Support Center
     in conjunction with CSCPAT_0245. It must be used ONLY for its
     intended purpose - to recover from the symptom described in
     file SYS$HELP:CSCPAT_024501*.RELEASE_NOTES where a tape device
     becomes allocated to a nonexistent process. The user of this
     program must have CMKRNL and WORLD privilege. To obtain
     additional information, contact the Customer Support Center by
     calling (800)345-9000.

     Device Name:
--------------------------------------------------------

  3. Verify that the device is no longer allocated using the DCL
     command 'SHOW DEVICE/FULL'. The device should no longer be
     allocated if the steps above were followed correctly.
