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

ECO KIT SUMMARY:

An ECO kit exists for Memory Channel users on OpenVMS Alpha V7.1-2.
This kit addresses the following problems: 

  o  CPUSPINWAIT system crashes may occur if Memory Channel 1.x 
     adapters experience hardware errors while Heartbeat Timeout 
     is enabled.

     Image(s) Affected:  [SYS$LDR]SYS$MCDRIVER.EXE

  o  Customers who install or upgrade to V7.1-2 or later versions
     of OpenVMS ALPHA may experience Hub Timeout errors, Memory
     Channel port re-initialization and virtual circuit closure on
     Memory Channel 1.0 or 1.5 devices.  This problem is not seen
     on Memory Channel 2.0  devices.  In some cases the memory
     channel adapter has been set offline and the customer must
     reboot to re-enable it.

     Image(s) Affected:  [SYS$LDR]SYS$MCDRIVER.EXE


INSTALLATION NOTES:

The images in this kit will not take effect until the system is
rebooted.  If there are other nodes in the VMScluster, they must 
also be rebooted in order to make use of the new image(s).  

If it is not possible or convenient to reboot the entire cluster at 
this time, a rolling re-boot may be performed.
