*OpenVMS, STORAGE] STRIPEVAXE02021 VAX V5.4 - V6.1 Striping ECO Summary
TITLE: *OpenVMS, STORAGE] STRIPEVAXE02021 VAX V5.4 - V6.1 Striping ECO Summary
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.

NOTE:  The installation kit for this ECO does not contain any
       executable images.  The appropriate image will be 
       generated by the object modules at installation time 
       depending upon the version of OpenVMS VAX to which 
       the kit is applied.


An ECO kit exists for the Striping Driver on OpenVMS VAX V5.4
through V6.1.  This kit addresses the following problems: 


NOTE: This kit contains a remedial to correct behavior caused by the 
      use of OpenVMS patch kit VAXSHAD09, "shadowing writes past the 
      legal length of an IRP for OpenVMS V6.1 and earlier".  In OpenVMS 
      V6.2, OpenVMS expanded the size of the IRP data structure.  The 
      VAXSHAD09 patch kit utilizes these values for 6.2 and earlier 
      versions of OpenVMS.

  o  Increase the size of the structure that contain the member IRPs.


  o  If a BIND fails because a stripeset is already bound,
     some of the existing stripeset data structures are

  o  When a stripeset is initialized using the /FILES_11 
     qualifier, a signed comparison is made against the 8.5 
     GB limit. This may cause a stripeset larger that 8.5 GB 
     to be created.

  o  The BIND_UNBIND_LCK descriptor is not locked down.  This
     might cause a PGFIPLHI bugcheck to could occur when binding
     a stripeset.

  o  Incorrectly clearing the UCB$W_REFC field causes a negative 
     reference count and dangling locks with cleared value blocks 
     for a stripeset device.


The system must be rebooted after this kit is installed to make use 
of the new images. If you have other nodes in your OpenVMS VAXcluster, they 
must be rebooted or you must install this kit on each system in order 
to make use of the new images.
