HP Services Software Patches - alpclus01_070
 
Modification Date:  23-APR-1998                                               
Modification Type:  DOCUMENTATION:  Editorial Modification                    

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.

ECO KIT SUMMARY:

An ECO kit exists for SYS$SCS on OpenVMS Alpha V6.1 through V7.0.  This 
kit addresses the following problems: 

Problems Addressed in the ALPCLUS01_070 kit for OpenVMS Alpha V6.1,
V6.1-1H1, V6.1-1H2, V6.2, V6.2-1H1, V7.0

  o  Node hangs while trying to boot after sending a request for
     cluster membership.  The problem is due to a node having zero
     send credits.  Most frequently, the connection manager SYSAP
     (VMS$VAXcluster) is the SYSAP effected.  This behavior can also
     occur when a connection is reformed.


Problems Addressed in the ALPCLUS01_070 kit for OpenVMS Alpha  V6.2,
V6.2-1H1, V7.0

      o  Incorrectly allocating a new CDT (Connection Descriptor Table)
         for an incoming connection request.  This ultimately exhausts
         the CDT list resulting in Cluster instability, loss  of
         connectivity and inability to reform a cluster.

 
INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted.  If the system is a member of a VMScluster, the
