ECO KIT SUMMARY:

A dupatch-based, Early Release Patch kit exists for Tru64 UNIX 5.1A that 
contains solutions to the following problems:

   1) Potential data inconsistency that may occur when a Cluster
      File System (CFS) client reads a file that was recently
      written to.  Stale data may be returned to the client.

   2) Multi-volume AdvFS v3 domains exhibit EIO errors not
      attributable to hardware.

More information can be found in the service notification titled "Tru64 
UNIX Stale CFS data and AdvFS v3 domain errors" available from the Compaq 
Support Reference Library for Tru64 UNIX. 

The Patch Kit Installation Instructions and the Patch Summary and Release
Notes documents provide patch kit installation and removal instructions
and a summary of each patch. Please read these documents prior to 
installing patches on your system.

The patches in this ERP kit will also be available in the next mainstream 
patch kit - Tru64 UNIX 5.1A Patch Kit 2.
