There is no way to do this, and I agree with you that this is an unpleasant situation. On several occasions I have had to set a box to floppy boot (usually when an emergency forces me to run a 25/7 or prev_cp and I am somewhat distant from physical console access but can get to a console server over the net) and if I am using this hack to get the box running in the first place I am in no hurry to run it through another reboot just to turn off the floppy boot option, particularly if I am not sure the system will come up again if I do happen to reboot it... jim

>> they should've spent more money on books and >>less on leather jackets..... Seems like a good opportunity to introduce myself...NetApp has recently made a substantial investment in the Educational Services organization, allowing us to improve/expand our base courses (and materials), as well as develop new courses. The NTAP 101 student manual has been completely rewritten (with a tab based TOC) and the NTAP 202 new manual is in the works. The new manuals are a different format and have more of the 'lecture' included, requiring less 'note taking' by the students (although more vs. less note taking is a highly debated subject in the training world). Classes, overall, have more lab time (input from our class evals). We are also creating WBT (web based training). Our first WB course is currently in beta. We have scaled down the 'giveaways' in class (they were pretty substantial) but have improved the multiple student/multiple class discounts. A point I'd like to make specifically on Jason's comment: >Even after taking the class I doubt I'd play with the special commands without tech support on the phone... at least not on a production filer. This is an important point which we stress in the 202 class. For reference, here's the URL to our web page: http://www.netapp.com/support/training.html Another URL for additional feedback and/or input on new/extended courses is: http://support.netapp.com/now/survey.html If you'd like to be on our mailing list, you can fill out a form on the web or send e-mail to registrar(a)netapp.com. This may be more than you ever wanted to know about training, but I appreciate the comments and the chance to put out some information. Ruth...

But that wasn't really the goal of the floppy boot; it was for things like installs and boting up a previous OS when the current one is crashing your filer and so on. Bruce

ramping performance
by Graham Knight 21 Apr '99

21 Apr '99

While doing some transfers to an F760 (5.1.2P2) the perfomance seems to ramp from good to lousy. I can find nothing wrong with the network - this is data coming from a system on the same subnet (100tx-fd). Data transfers between other systems on the same segment do not show these types of performance problems - here's a typical output from a sysstat 1: ( i am reading from one place on the filer and writing to another) CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 12% 232 1 0 949 947 640 0 0 0 12 34% 644 0 0 2425 2445 2336 0 0 0 12 12% 233 2 0 1020 1015 1049 0 0 0 12 4% 0 1 0 1 0 0 0 0 0 12 4% 2 0 0 0 0 0 0 0 0 12 19% 488 4 0 1970 1984 1724 0 0 0 12 49% 448 0 0 1700 1656 2226 7075 0 0 12 15% 139 0 0 128 158 148 3976 0 0 12 4% 0 1 0 0 0 0 0 0 0 12 19% 139 8 0 601 613 708 0 0 0 12 25% 621 0 0 2702 2719 2342 0 0 0 12 19% 467 0 0 2049 2027 1888 0 0 0 12 4% 16 1 0 20 3 0 0 0 0 12 4% 91 1 0 15 16 0 0 0 0 12 Anybody have any insights into what might be causing this?

RE: Legato with NT

Just FYI (nothing official), but I can say that in the limited testing I did with Legato over CIFS to the filer everything seemed to work just fine. I was able to back up and restore both UNIX- and NTFS-style files with no problems. The security and other metadata were fully preserved. Make sure you are doing the backups and restores from an NT admin account that maps to 'root' if you are working with files that have UNIX-style security. The one problem I remember is the same one Michael Salmon mentioned: make sure you are accessing the filer as a domain administrator, not the local administrator (which is the default unless you specify "domain-name\administrator").

Anybody using 3com switches with NetAPP?
by Jaye Mathisen 16 Apr '99

16 Apr '99

I have both my ports on a linkswitch 3000, at 100mb, full-duplex. Both ends are configured manually for 100mit, full duplex. I do not believe when i was running 4.3.4, that I got any errors. But now, with 5.3, I'm seeing occasional errors. (a few every 10-15 seconds). In this VLAN, there's only 1 other device talking to the netapp, and it's configure for 100mb, full-duplex as well, and it sees no errors either coming or going. As I said, I believe this is new behaviour. I have rebooted everything just to make sure, and double checked it all, and it's all full duplex 100mbit. Cabling is short, and tests fine on a Fluke 682 lan meter... Anybody else seeing something similar before I go knocking on Netapps door?

Yeah, this has been a well known problem for years, but I had trouble getting action on it until engineers actually had to deal with the problem first hand and realized just how bad it was. As to the fix, I don't recall what it was, but I recall a proposal similar to the one you listed being considered and rejected (for example, your suggestion wouldn't work, since when the user fails to go over quota they'll generally fall right back under it, thus resetting the flag). >[Hmm; I should put support(a)netapp.com (or whatever) on autosupport; >maybe then they'll listen after getting a 30MB email message every >week ;-] I think they already filter such things.

Samba client and filers
by Garrett Burke 16 Apr '99

16 Apr '99

Hi, Anyone know of any issues with smbclient (version 1.9.18p8) and filers running CIFS (OnTap 5.2.1)? Session setup is failing. I can use smbclient to connect to my NT servers but not the filer. I notice from the debug output of smbclient that it says "Using encrypted passwords" Could this be the problem? Can't see anything on the smbclient man page to force it to use unencrypted passwords. Here's some "-d 3" output from smbclient: Connected max mux 32 max vcs 1 max raw 65536 capabilities 0x42dd Sec mode 8195 max xmt 8192 Got 8 byte crypt key Chose protocol [NT LM 0.12] Server time is Thu Apr 15 14:16:23 1999 Timezone is UTC+1.0 Password: Using encrypted passwords Session setup failed for username=<username> myname=<FreeBSD hostname> destname=TOASTER ERRSRV - ERRerror (Non-specific error code.) (Before you all say "use NFS", I'm writing some monitoring tools that will run on a FreeBSD box and will actually fetch a file from the filer and calc a CRC to ensure it's ok. This way I know the file service is available) Thanks, GB

If this flag is set, it indicates if a message has already been logged about that quota being exceeded. * Every time the quota entry is checked (during a disk write, or whatever), do the following: if (quota not exceeded) { flag = 0 } else { /* quota exceeded */ if (flag == 0) { syslog("quota exceeded ...") flag = 1 } } I.e, don't bother logging a message if that user has already had a message logged about them. However, if they go under quota, clear the flag, so we get a message when they exceed it again. The only response I've received (second hand) is along the lines of ``we've fixed it, but a different way''. [Hmm; I should put support(a)netapp.com (or whatever) on autosupport; maybe then they'll listen after getting a 30MB email message every week ;-] > > I'd recommend using a userland program (on login) to regularly tell > users how close they are to exceeding their quota, in addition to > monitoring quotas for your own information. > I wrote a perl script which can do all sorts of funky reporting based on the output of `quota report', including playing ``what if'' games based on the quota report and the `/etc/quotas' file you're about to apply. It currently works for OnTAP 5.2.1, although I could probably hack support back in for 4.x if people wanted it. Checkout: http://www.cs.rmit.edu.au/~lukem/src/quotarep An aside; on our main student filer (an F330), we have nearly 6000 users, and 2500 separate quota entries; we generate an individual quota entry per student based on subject enrolment. Works quite well, although the `quota resize' takes over two minutes to complete, and I'm a bit sick of the huge messages file :/ We've had our share of quota bugs (especially the ``quota -v doesn't display anything'' problem), but in general, the NetApp quota system works well. It's definately easier to manage than standard UFS quotas (as well as the ability to recalculate on the fly; UFS quotacheck requires a quiscient filesystem to work).

Ack, sorry Garrett, I just noticed that you're running Samba 1.9.18p8 and I gave you a patch for Samba 2.0.3. I took a look at the Samba 1.9.18p10 source I had handy and it wasn't immediately clear to me what the correct patch is. Samba 1.9.18p10 uses a BUFFER_SIZE constant (defined as 0xFFFF) when calling Session Setup, but that constant is used in a *lot* more places than the CLI_BUFFER_SIZE constant in Samba 2.0.3, so I'm hesitant to fiddle with it. You're probably better off downloading 2.0.3 and applying that patch, since I'm sure that will get you a working smbclient. But if you want to stick with 1.9.18, you can give the following (untested!) patch a shot. (Let me know how it goes.)

Looks like drive model numbers. Anybody slapped on 3rd party drives from that list and see if they work? I could always use a different source to update my filers.

This way I know the file service is available) Hi Garrett, Yes, there is a problem with the filer's handling of Session Setup requests in 5.2 that prevents smbclient from connecting. What's happening is smbclient is trying to connect with a client buffer size of 0x4400, but 5.2 rejects any client using a buffer size greater than 0x2000. So, you can recompile smbclient with the CLI_BUFFER_SIZE constant set to 0x2000 to get an smbclient that can connect to 5.2. (See below for the patch.) With that patch, smbclient should work well enough for you to at least connect and fetch a file. (There could be other bugs, though... we haven't spent any time testing smbclient yet, on any release.) In 5.3 this client buffer size limitation has been removed, so that patch isn't required. Unfortunately, though, a bug was introduced in 5.3 that causes smbclient to get filenames that are short by one character (do a "dir" and you'll see what I mean). That shouldn't prevent you from connecting and fetching a file, though. This bug will be fixed in 5.3.2. (It only affects smbclient, by the way.) Hope that helps, Matt *** samba-2.0.3/source/include/client.h- Fri Feb 5 18:17:46 1999 --- samba-2.0.3/source/include/client.h Thu Apr 15 12:18:47 1999 *************** *** 27,33 **** /* the client asks for a smaller buffer to save ram and also to get more overlap on the wire.

RE: Dump command issues?
by Melvin, Grant 15 Apr '99

Hi Mike, Officially NetApp doesn't support the ATL L200 or L500, but we do have a bunch of L200s in-house and we see different issues with them which normally results in a firmware upgrade from ATL. The latest upgrade is version 28 you may want to try this. FYI, the only "stackers" we officially support are the Quantum 4700 and Breece Hill Q2.15. We have had issues with timing on other tape stackers and have made recent changes to Data ONTAP that should cope with these variations, but we have no roadmap to "certify" a bunch more stackers. I know that 3rd party vendors have also been having some difficulty getting the L200/L500 units to work via NDMP without software changes. So if you are using a 3rd party tool which is NDMP-compliant or NOT then you may want to ask about their support (think patches) for these units. If you still have an issue after getting your unit upgraded/ checked out then feel free to send me an e-mail with your dump output and we'll see if we can get to the bottom of it. Cheers, Grant -----Original Message----- From: Mike Ball [mailto:mball@rtp.opensystems.com] Sent: Tuesday, April 13, 1999 10:54 AM To: toasters@mathworks. com Subject: Dump command issues? Currently we have a F720 filer and a ATL Powerstor L500 tape library attached locally. We are running into a issue when we try to dump to multiple tapes. If we use the command below, it is supposed to dump our entire vol0 (90GB of data) to multiple tapes in our tape library. rsh -l dump 0uf urst0a,urst0a /vol/vol0 Unfortunately, the dump command above backs up to the first tape, then rewinds the tape when it is full but never unloads it. The first tape is then overwritten as the dump continues. The dump command above does not unload the tape and continue the dump onto the second tape in the library. Has anyone else experienced this before, or does anyone have any recommendations to correct the problem? Thank you, Mike Ball

RE: Migration problems
by Benn, Paul 15 Apr '99

Just for clarification.... The problem with Microsoft's Migration Tool for NetWare is that you can only migrate data to a domain controller (the problem exists for NT member servers as well as filers), right? I'm not sure how helpful this link is to you at this point (I just discovered it myself) but here it is anyway: http://support.microsoft.com/support/ntserver/migration/ Regards, Paul Oh, and to answer your question: Personally, I've never heard of any other tools to do this. I have, however, performed a NW=>NT migration. We chose to do everything manually because the end result was much cleaner. We did use the Microsoft tool, but only to migrate user accounts. The company was large so we performed the migration in steps (say 100 users per weekend and ~20 each week day). -----Original Message----- We tried to do this at the first time with a tool called Migration Tool for Netware. With this tool it is impossible to transfer the data from the Novell servers to the Netapp.

Migration problems
by JD Ambagtsheer 15 Apr '99

We are working on a migration project (Novell => NT) and want to transfer data from 3 Novell servers to a Netapp (F720) fileserver. Because of the different file systems, the right structure must also be transfered and translate. We tried to do this at the first time with a tool called Migration Tool for Netware. With this tool it is impossible to transfer the data from the Novell servers to the Netapp. Now we have the following question: - Does anyone already had a migration from Novell to a Netapp (or an other migration to a Netapp)? - Are there some tools to realise this? I hope someone has answer to those questions. Greetings, Jan-Dirk

Macs & NFS
by Clark Shishido 14 Apr '99

14 Apr '99

I just found that there is still one MacNFS client that is shipping. In an earlier post I had stated that there were no MacOS NFS clients available. Ascend bought Intercon which had published NFS/Share. It is now a part of IntragyAccess. I haven't seen it, but it might be an option for those of you who don't want to dedicate a UNIX server to reexport NFS shares via KA-Share, EtherShare, or netatalk. I looked around a little bit and PCZone/MacZone seems to have copies available. http://www.ascend.com/2405.html --clark http://macunix.com
