ECO KIT SUMMARY:

An ECO kit exists for MCDRIVER on OpenVMS Alpha V7.2.  This kit addresses
the following problems: 

Problems Addressed in VMS72_MEM_CHAN-V0100:

  o  Hub Timeout Errors, Memory Channel Port Re-initialization, Virtual
     Circuit Closure 

     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

  o  Heart Beat Timeout causes a CPUSPINWAIT system crash

     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


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.
