OpenVMS VAXDRIV03_062 VAX V6.2 PADRIVER/PEDRIVER 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.

ECO KIT SUMMARY:

An ECO kit exists for PADRIVER and PEDRIVER on OpenVMS VAX V6.2. 
This kit addresses the following problems: 

Problems Addressed in the VAXDRIV03_062 Kit:

  o  Adapters such as the KFESA restart and log "Invalid Buffer
     Name" errors.  INVALID BUFFER NAME errors are a known issue
     that occur as a result of an incompatibility (or "race
     condition" as mentioned in the original case text) in certain
     hardware where there is a different perception of when a DSSI
     packet has been "received" as good.  If a reset occurs during
     this time (before BUS FREE), the initiator will resend the
     packet to the target that has already accepted the packet as
     "good".  If the resent packet is the last in a buffered data
     transfer, the re-transmit attempt may not occur until after the
     target has invalidated its buffer descriptor resulting in the
     error.

     This appears to happen in systems at times of heavy I/O
     activity.

  o  Any message which is received with an SCS$W_STATUS field of 0 
     will cause OpenVMS to crash.  The  crash  will be an "INVEXCEPTN, 
     Exception while above ASTDEL" in SYS$SCS.  This situation will not 
     occur very often.  It is basically caused by non-compliance to SCS
     specifications or by errors in firmware.


Problems Addressed in the VAXLAVC01_062 ECO Kit:

  o  Nodes in an LAVC (Local Area VAX Cluster) may CLUEXIT bugcheck
     in mixed ENET/FDDI environments where duplicate hello messages are
     being produced (i.e., out-of-rev bridge firmware).


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 entire
cluster should be rebooted.
