RE: "secret" rc_toggle commands

[Weeks, Thomas] Since this is not an official NetApp supported site.. I would think this a good place to start this FAQ... BE FOREWARNED!

Well... I'm afraid to run any on our filer as it is our main production box... Although I have already runa few that seemed to be obvious... Anyone documented any of these commands? How about giving us some feedback? (or just send it to Kelly since he has volunteered to start the FAQ.. that is.. unless NetApp doesn't mind providing some of us power users with some simple form of FAQ/docs... ;v) I can be descrete...

load tracking
by Daniel Quinlan 21 Apr '98

Does anyone track or log the load (CPU, NFS ops, network in/out, etc.) on their Network Appliance boxes (over time)? If so, I'd like to hear about your experiences. Dan

"secret" rc_toggle commands
by Weeks, Thomas 21 Apr '98

21 Apr '98

Does anyone here have an FAQ on the rc_toggle_basic command set? I've know about them for a while now but have never been able to make full use of them. I have printed out all the commands but don't want to run any of the unknown ones without knowing exactly what they each do... I have used a couple of them (like scsi_inquiry and the like)... Thanx all... Tom D Tek

If so, I'd like to hear > about your experiences. We use mrtg to plot things like nfsops/sec, network i/o, disk space status, etc. All these data are collected using snmp, qhich is what mrtg usually does, anyway. This gives us, without too much hassle, a graph of tha last 24 hrs, last week, month and year - these graphs can be very useful to track down various problems (and to monitor available diskspace). Mrtg is free software, i can't remember off the top of my head where to find it, but it should be quite easy to find. If there's any interest I'm sure I can dig up some example configs from our setup. -- ---Ketil Kirkerud Elgethun, SOL System

Filer and IIS
by Jimy Liu 20 Apr '98

20 Apr '98

Hi sirs: I have one filer share directory to one NT server.(NT mount filer's /home/www as its f:\ directory) And I set up Internet Information Server(IIS) Web's root directory as f:\ . Then I use brower to open NT's web page from IIS. The browser show "Can not find the object". And in IIS web directory setting shows "this directory access denied. But I can using brower to open file in f: directory . Why can not access through IIS ? There is must something wrong on filer or IIS . Jimy

I know in a previous version, we ran into a problem where the CPU pegged high when scanning a deep directory tree, hundreds or thousands of entries deep, that someone had created. I believe this impact was alleviated in later releases but I can't be certain of that having not tried it myself. So, unless your filer is just heavily loaded and/or short of memory when doing your backup, I'd suspect something like a deeply nested directory tree. Perhaps you can locate it an remove it. Then again, it could be something entirely different. :/ Bruce

It is not unusual for Microsoft to violate their own spec. I don't know specifically what is wrong in IIS, but probably the filer is advertising something perfectly reasonable (that win95 doesn't), but IIS isn't handling it correctly. If Microsoft says this is a problem with IIS, then I see no reason to doubt them. (Yes, they may initially accuse Netapp, but the impression I am getting is that they aren't doing so now.) >About two month ago, my customer ran Notes server on NT using NetApp >filer => Notes boot Fail . >If she ran Notes server on this NT using another NT's disk as network >drive => Notes boot Success. Again why filer can't ? >(ps: I hope to resolv IIS with filer first ) I know these sorts of things happened in earlier versions of the filer CIFS software. Whether or not it happens now is hard to say. I would upgrade your filer software, try it, and if it still doesn't work, contact Netapp so they can open a bug on it. Bruce

Silly Microsoft. :( I dunno... seems like Microsoft "won" to me, since you didn't abandon IIS. Instead you were coerced into a more expensive and more NT-centric solution. (Before someone questions whether or not such a solution is really more expensive, please don't... I don't want this to turn into some flamewar about Microsoft and/or NT.) Bruce

The small amount of failures that NetApp finds >could be attributed to manufacturing defects and delivery problems. I basically agree (I'm not sure if I'd draw the line at 1 in 200), but I would point out that if they can be attributed to manufacturing defects, then you are just as likely to get such a defect direct from the supplier. So again, going through a supplier like Samsung isn't going to be more reliable, although how much less reliable (i.e. 0.5%) may be negligible for your particular environment. It would, however, somewhat dispel the notion that the filers push the edge of the components. Bruce
