The cost per usable gigabyte of my F630's has received *considerable* executive scrutiny recently. So I'm just a leeeetle sensitive about this kind of thing. > So are you dead-set on living dangerously? Maybe, maybe not. My experience with my existing (identical) F630's suggests I can get away with it. On the other hand, it's bad karma to turn away a life jacket when somebody offers you one "just in case." So I dunno. Let's say, for the sake of argument, that I did decide to live dangerously. So...what's the best way to get a vol0 with one RAID group in it? Brian brice(a)gnac.com

I thought the 600 ports were for rsh, but by they alternate between TCP and UDP, and aren't contiguous, I don't know. I have no idea what 10000 is for. Bruce

I should add that this happened to us just a few days ago: - xntpd died on our adminhost (that ran the cron job to set the NetApp dates) - time drifted by 8 minutes on the adminhost and the filers over the course over a few days - someone started having problems, managed to figure out that it was because of the time drift, and we fixed it. (Other people probably had problems, but didn't report them.) To prevent it from happening again, we're remotely monitoring the system time of the adminhost (using "mon") to make sure it doesn't drift off again. Incidentally, there seems to be no way to remotely query the system time from a NetApp (except by creating a new file and running stat() on it, or by using unsupported/hidden commands). However, I'm still saying that I don't want NTP until other supported protocols (such as NDMP) start working reliably. Dan

Calling all F630/FC-AL users
by just me. 02 Sep '98

02 Sep '98

If you are a NetApp F630/FC-AL user and have encountered any (especially recurring) glitches with interactions between the Fibre Channel host adapter and OnTAP, or recurring FC hardware failures I'd appreciate hearing from you. On the flip side, if you are a NetApp F630/FC-AL user and have seen perfect performance from your filer, I'd love to hear about it too. We have had the first F630/FC-AL in Japan in our machine room for the last month or so, and have been through some interesting experiences.

If it is, then the filer should be registering all your interfaces with the WINS server using the standard WINS multihomed registration protocol. (This is how a multihomed NT server would register with WINS.) In that situation, CIFS clients that use WINS resolution will choose one of the filer's IP addresses from the registered list. (Depending on the type of client, the address selection algorithm varies; for example, older Microsoft clients tend to choose the address randomly, while NT4 SP3 clients try to be more intelligent. Microsoft's MSDN support web site has some articles detailing this -- try searching for "multihomed" and/or "WINS".) (By the way, as of version 5.1 of Data ONTAP there is a new ifconfig option, "-wins", that can be used to disable WINS registration for a particular interface. It's documented in the na_ifconfig(1) man page. Maybe you should try setting that option on your e0 interface?) If your filer's CIFS is *not* configured for WINS, then CIFS should be broadcasting its presence on each of its interfaces. For example, if you have two interfaces, e0 at 10.0.0.1 and e1 at 192.168.0.1, CIFS will periodically send a broadcast on e0 that reads "FILER is at 10.0.0.1", and on e1 the broadcast will read "FILER is at 192.168.0.1". (Note that each packet only mentions the IP address for its particular interface.) This is how an NT server that isn't configured for WINS would announce itself. Hope that helps some - let me know!

Seeing quad 10/100 ethernet ports from NT
by yrsuser 01 Sep '98

01 Sep '98

Hello, We have a new F230 installed here (5.1R1, 1.9i firmware), with a Quad 10/100 card in it. I've configured the 4 ports, and have no problems talking to (or mounting NFS from) any of them from the Unix side of the house. Unfortunately, the only network connection that shows up on the NT side of the house is the one on the F230 mother- board (e0), which is not the one I want the users accessing. I can map a network drive using the 4 "other names", (only if I attach as "nobody", but that's probably another problem), but I can only "see" the main port in the network neighborhood. And I'd rather the users not have to memorize the names of the different ports. I can use the server manager on the PDC to add the other 4 names, but they only show up as ghosts, and the PDC tells me that they are not responding if I try to do anything else with them. (I can ping them, though). Any thoughts? I really don't want to use the main motherboard network connection (currently 10Mbps) to handle anything other than Root telnet sessions to the filer.

RE: Redbrick?
by Clarke, Bruce 27 Aug '98

27 Aug '98

We have one customer in South Africa that is known to have put Redbrick on a filer. I have been told its in an NT environment. Attempts by NetApp to get Redbrick "officially" interested have so far gone unanswered. If you would like to drop my name to the Redbrick sales rep, please feel free to do so.

"quota resize" still doesn't work right on 5.0.2
by Stephen C. Losen 27 Aug '98

27 Aug '98

We have a default quota of 10M, which is the first line in /etc/quotas: * user 10M 10K Here is a quota report for a user with no entry in /etc/quotas: quota report /h1/s/sj/sjs3j Type ID Volume Tree Used Limit Used Limit Quota Specifier ----- -------- -------- -------- ------- ------- -------- -------- --------------- user 30967 vol0 - 472 10240 113 10240 So now I add this line to /etc/quotas /h1/s/sj/sjs3j user 20M 20K And I run quota resize quota report /h1/s/sj/sjs3j Type ID Volume Tree Used Limit Used Limit Quota Specifier ----- -------- -------- -------- ------- ------- -------- -------- --------------- user 30967 vol0 - 472 10240 113 10240 The quota for this user has not changed. Only turning quotas off and back on does the trick. The quota resize command issued no error. I read an earlier post to this list that indicated that this was fixed. Has anyone actually gotten this to work? Steve Losen scl(a)virginia.edu phone: 804-924-0640 University of Virginia ITC Unix Support
