NIC/SCSI combo card is in slot 1 while slot 0 (bottom most) occupied by USB/HDI
card. Cat 5 cable between RCNI and AW51G is P0971XM Rev F. Local field service
visited many times collected nfd_log including the last week visit. Lastly we
are asked to install QF1008295 and QF992053, I think2nd OF is no relevance to
us (our hardware is AW51G, AW51B, WP51B). We do not have spare Ethernet/Serial
splitter cable, do not see stations sending extreme amount of multicast
messages, normally nfd_log entries are with TL layer request, but suddenly see
burst of node bus requests with CRS error and finally CPs failures reported
with no actual failures.
We are reviewing advisory 2007001abi in addition to the HH1050, FAQ621, FAQ631
to draw the action plan.

Is your RCNI connected to the NIC/SCSI combo card in Slot1 ? should be
using the hme interface not bge.
I suggest that you have Foxboro Field Service or TAC closely analyze the
nfd_log.
Also, refer to HH1050, FAQ621 and FAQ662. If you are using the Foxboro
shielded Cat5 cable for your RCNI to
AW51G connection, ensure it is RevC or higher for P0971XK, XL, XM and XN.
The Ethernet/Serial splitter cable on the AW51G can be source of problem if
the serial part of the cable is malfunctioning it
is used to read the letterbug and switch the A and B connections from the
RCNI to the NCNIs
Also use SMDH performance counters to look for stations with out of bounds
errors in the MAC sublayer.
Do you have any stations sending extreme amounts of multicast messages ?
Regards,
Scott

Hello List
We have configuration of AW51G running IA Batch V 8.1 (Unix) with CP40A/CP60
cluster on node bus with RCNI/NCNI combination. AW IA version V 7.1.1, WPs
style B at 6.5.2 and one AW style B at 6.5.2.
We are facing random CPs failure report at AW51Gwhich is default node bus
master though CPs never failure actually. Look at its nfd_log files showed CRS
error and cable faults. However when NFD master shifted to AW51B no CRS error
and CP failures reported in the nfd_log file. Since IA Batch is running at
AW51G we face lot of IA Driver error and many times batch manager got stopped.
We already tried changing AW51G, new RCNI, tried different location for NCNI in
1X8 structure, replaced FO cable between RCNI & NCNI and those between 1X8
structures with new end terminators. But situation remain the same.
It appears that node bus alarms in nfd_log with CRS errors due to version
mismatches between both AW (7.1.1. and 6.5.2) as AW with 7.1.1 has/require
faster diagnostic response compared to AW with 6.5.2. We tried workaround
suggested by TAC to kill the nfd_8023 at AW51G but end up with all CPS actually
failing !
Is there anyone faced similar problem and suggest work around.
Best Regards
G R OMPRAKASH
