ECO KIT SUMMARY:

An ECO kit exists for DISMOUNT on OpenVMS VAX V6.2.  This kit addresses the
following problems:

Problems Addressed in VAXDISM02_062:

  o  A possible system crash occurs during Host Based  RAID  Unbinds
     with  MME code enabled.  A mailbox read synchronization problem
     causes the crash.

     This problem only occurs when a host-based RAID UNBIND  command
     is done while an MME-based application is running.

     This problem can occur in several different code areas  of  the
     operating system.  In order to eliminate all known instances of
     this  problem,  the   following   remedial   kits   (or   their
     supersedants) will also need to be installed:

     VAXSYSA02_062
     VAXBACK03_062
     VAXMOUN03_062
     VAXINIT01_062
     VAXMTAA03_062

  o  A process using MME could potentially "miss" the VOL1 label  on
     a  tape.  Also, a process could "hang" trying to send a message
     to the MME process.


Problems Addressed in VAXDISM01_062:

  o  SSRVEXCEPT in DISMNTSHR when a user (or application) attempts to
     DISMOUNT a tape that is in use by RTF/SLS.

     This problem is corrected in OpenVMS VAX V7.0
