2109.0. "Network ping YES, SCSI ping NO, what could be the reason ?" by COL01::VSEMUSCHIN (Duck and Recover !) Tue Jun 03 1997 16:06

    I have another problem with cluster, described
    in 2108:
    
    Y Cable ----- TriLink ------ Y Cable
      |            HSZ40             |
      |            HSZ40             |
    KZPSA                          KZPSA
    AS1000A                        AS1000A
    
    Both alphas have DUNIX 3.2G with the newest KZPSA 
    patch installed. ASE 1.3. Sometimes they cannot
    ping each other ower SCSI. Only network pings work.
    Could it be hardware Problem or it can be caused
    by high load on one of computers (or Just Another
    Patch is necessary. NB, besides the mentioned above
    there are no other patches installed)

It could be hardware or software, although from what you are
saying it sounds more like hardware.  It would take an extremely
large load for a very large time to make the software issues
become a problem. Do you see any entries in the binary error 
log (use 'uerf' or 'dia' to investigate) at the same time as the 
entries in the kernel.log file?

You could try increaing some of the ASE AM timer values as
described in Chapter 1.2.5 of the V1.3 ASE Administration 
manual.  This would raise the threshold that ASE uses to
detect failures.
