5300.0. "FDD cluster and Cluexit questions..." by VAXRIO::MAURO () Fri Apr 25 1997 20:56

Hi,

I have a FDDI/SCSI cluster with two ASRVS, one 2100 and one 8400. I'm
having CLUEXIT crashes in both systems, at least one time a day. I already
checked pool expansion failures, pagefiles full and other stuffs that would
justify VC to be closed. During my analysis the most significant thing I
found were plenty of errors in the Bus FWA (SCA) and errors logged in
errorlog few seconds before the CLUEXIT. Right now I have the RECNXINTERVAL
set to 120 seconds and the cluster is more stable. The Field Service people
is trying to find a HW error, but they still suspect of a Software problem.

I already applyed the patches: ALPLVAC01_062 and ALPLAN04_062...

My questions are: Is there any problem work with RECNXINTERVAL set to 120,
since its default is 20?
Are you  able to tell me if the NCP line counters, displayed in the end of this
text, presents a HW error situation in the FDDI bus?

Any help will be very welcome, Mauro.

5300.1	LAN problem indicated so far...	STAR::BOAEN	LANclusters/VMScluster Tech. Office	`Tue Apr 29 1997 14:45`	43
	Hmm, The PEdriver BUS structure is telling you that the LAN driver is returning HELLO packets with transmit fail status: HELLO Xmt err 411 There have been 411 failures out of 9745 multicast transmits. Since PEdriver only uses multicast for HELLOs. that's a pretty high failure rate. Especially if they occasionally happen in bursts. This error is indicative of a LAN adapter or driver problem. HELLO transmit failures can result in CHANNELS & VCs on other nodes being closed due to CHANNEL listen timeouts. There is nothing that indicates a problem in PEdriver so far. Try SHOW LAN /COUNT and see what the LAN driver error counters show for FWA. recommend using SHOW PORT /CH/VC=... then a SHOW /BUS and SHOW LAN/COUNT to get a set of correlated information. You mention the error log, but don't say what kind of errors are being logged and how often. I'd guess you're logging PEdriver VC closures? PEdriver is retransmitting about 1 in 1000 packets which is on the high end of the normal range, but the roundtrip times look good. I suspect that normal LAN burstiness is causing an occasional retransmit. The ReRcv counts hint at this. Important info is that normal traffic packets are NOT getting transmit errors. This seems to be a problem that only affects multicast transmits... Is this a dedicated FDDI ring between the 2 alphas, or is it shared with other network traffic? 'Gards, Verell
5300.2	Informations...	VAXRIO::MAURO		`Tue Apr 29 1997 17:10`	516
	Both nodes from the cluster are connected to DECcon 900 MX, that is part of a very large FDDI ring, with over 800 stations. Right now was installed a second direct FDDI conection between both nodes. In the ASRV8400 was installed a second DEFPA and in the ASRV2100 a DEFEA. What I didn't understand is that even in this second conection are we can see errors through SHOW PORT in both FDDI buses, but the connectio using the DEFEA doesn't presents errors, as you can see in the end of this entry. The errors looged in errorlog, just few seconds before teh CLUEXIT were FATAL DATALINK ERRORS pointing to FWAX. I think the system are still up because the RECNXINTERVAL, because it still shows VC closure but without to crash. --- Port Descriptor Table (PDT) 8151D488 --- Type: 03 pe Characteristics: 0000 Msg

5300.4	Why DEFEA doesn't log errors?	VAXRIO::MAURO		`Mon May 19 1997 20:13`	19
	Don't get upset with me, but the Hardware people ask me every day about this problem, mainly because they installed a second FDDI interface in both cpus, making a direct connection betweem them. They are not able to understand how can happen PEA0 (DATALINK ERROR) errors in this new connection, since it doesn't goes through the FDDI ring. The matter is that the EISA FDDI interface (FRA = SYS$FRDRIVER) doesn't log errors, while the PCI FDDI interface (FWA = SYS$FWDRIVER) in the other node still log errors (SDA>SHOW PORt/ADDR=PDT_ADDRESS) and they are connected directly. Is there any I can check or suggest them to check? Does it justify to open an IPMT? The SYS$FWDRIVER is from 31-JAN-1997 18:08 and was installed with ALPLAN04_062 (most recent patch). One more question: In this environment with two FDDI connections, how the PEdriver select the preferred path? Thanks, Mauro.
