David, Exactly what kind of issues are you seeing. I have the exact same setup except I have Gigabit instead of 100Mb. The issue primarily seems to be opening Office files from a share can take 30+ seconds. Other files types don't seem to be such an issue although I've personally seen a tiny text file take 20 seconds to open in Notepad. I've been the lone voice in the wilderness claiming it's not a Filer problem although it sounds like that might not be entirely true. We did see that running NAV with network drive checking enabled significantly made file access slower. We've done extensive testing and trouble shooting with the local NetApp folks. They discovered the NAV problem. The biggest reason I've not been looking at the Filer as a source of the problem is we've experienced the exact same behavior when accessing files from a share on an NT server. That in conjunction with some packet captures we've done seem to point to a problem with NT's TCP/IP stack. The stack starts out using very small packets and takes forever to ramp up to a decent packet size (Win2K is much faster - in tests a Win2K box on 100Mb ran laps around an NT server using Gigabit). We also use NIS as our primary means of authentication on the Filer and we still haven't ruled this out as an issue. I'm certainly interested in learning more about your problem and everything you learn/hear. This has been made a "top priority" for me to resolve and it's been frustrating because there doesn't seem to be a "smoking gun" and in the meanwhile management and users are cursing the good name of NetApp. Michael Cope Unix Systems Administrator Isis Pharmaceuticals mcope(a)isisph.com

We've had the same issue in isolated cases on our filers running 6.1R1P1. Our clients are running NAV CE. What have you found out about Norton Antivirus Corporate edition in this combination?

Nixon - By default the filer updates the NIS group cache once a day.

Bug in /etc/sysconfigtab (ONTAP 6.1.1R1)
by Rune Bakken 27 Nov '01

27 Nov '01

Hmm, just noticed (after returning home after a service window) that the filer I just installed another FC card (X2030B) in slot 2, didn't like the card in that position. The error message in the autosupport mail was: sysconfig: QLogic ISP 2100 32-bit Fibre Channel card (PN X2030B) in slot 2 must be in one of these slots: 8,7,6,3,3,1. It didn't hit me untill I spent 10 minutes talking to someone at the frontline of NetApp Support, that I did install the card in the correct slot (I did verify with the system configuration tool in NOW before installing). I blame the time of night, but as more time spent looking at the error message, I still could not shake the thought that something was wrong with the pattern "8,7,6,3,3,1" According to the lady, (and BUG 54796) the work-around was to ignore the error (slot 2 is supported) or move the card and wait for the next release of ONTAP. I edited the sysconfig instead to read allow F740 X2030B 3 8,7,6,3,2,1 1 and 'voila', sysconfig -c did not complain anymore. I felt better, atleast - even without NetApp support. >>>>>>>>>.rune -- Rune Bakken "I feel sorry for people who don't drink.

RE: Upgrade from F740 to F840
by Todd Phillips 27 Nov '01

27 Nov '01

Fairly straight forward. There is documentation out there if you search the NOW site. I have it but, it's on my other PC. I'll send it to you when I get a chance. Basically, all you do is an OnTap upgrade. Just unzip the new system files, not the boot disks, in the /etc directory, enter "download", halt the Filer. Swap heads and boot up. Be careful about things like NIC slot numbers, hostnames, netbios names, ip addresses, DNS, NIS and things like that. Other words, if you're using the onboard ethernet on your 740, its name is 'hostname'-e0. If you go to Gb-E or even another 10/100 port on the 840, your host name will change to 'hostname'-e8 or something.... This may screw up your DNS and possibly NIS. So, my point is, review the entire config and think about what may change and the possible ramifications. Hope that helps. -----Original Message----- From: Uros Lampret To: toasters(a)mathworks.com Sent: 10/26/2001 5:05 AM Subject: Upgrade from F740 to F840 Hi! I intend to upgrade from F740 to F840. I will only swap heads and keep the disks. I can't seem to find document describing this procedure. Any body done that? How do you change ONTAP from Alpha to Intel version? Regards, Uros

NIS group trouble
by Leif Nixon 23 Nov '01

23 Nov '01

It seems my filer (F720, ONTAP 5.3.6R2) caches NIS group lookups even if nis.group_update.enable is set to off. This is what happens when I add the user "testuser" to the group "rally": Initially both a Unix NIS client and the filer agree that the user isn't in the group: UNIX: % ypmatch rally group UNIX: rally:*:31042:jfrid,leif FILER: jar> ypgroup testuser FILER: User "testuser" belongs to the following group(s): FILER: name: testproj gid: 31038 FILER: name: testprod gid: 31039 Then I add the user to the group and do a ypmake. The Unix client immediately picks up the change: UNIX: % ypmatch rally group UNIX: rally:*:31042:jfrid,leif,testuser But the filer doesn't: FILER: jar> ypgroup testuser FILER: User "testuser" belongs to the following group(s): FILER: name: testproj gid: 31038 FILER: name: testprod gid: 31039 The filer is supposed to not cache group lookups: FILER: jar> options nis.group_update.enable FILER: nis.group_update.enable off In this state, the user can access the group's files just fine from an NFS Unix client, but gets "permission denied" when attempting the same from a CIFS client. Clearing the WCC cache with "wcc -x" doesn't help. Trying to manually force a group cache update doesn't work: FILER: jar> options nis.group_update_schedule now FILER: Local NIS group update failed now. NIS group caching is not enabled. The only way out of this state I've found is to enable group caching and then disabling it again. This forces a group update. FILER: jar> options nis.group_update.enable on FILER: Fri Nov 23 14:24:21 MET [rc]: NIS: Group Caching has been enabled FILER: Fri Nov 23 14:24:21 MET [nis_grp_updater]: Local NIS group update successful. FILER: jar> options nis.group_update.enable off FILER: Fri Nov 23 14:24:27 MET [rc]: NIS: Group Caching has been disabled Now the ypgroup command stops working: FILER: jar> ypgroup testuser FILER: NIS Group cache not yet updated. But at least the credential mapping is correct: FILER: jar> wcc -u testuser FILER: (NT - UNIX) account name(s): (SOFTLAB.LIN\testuser - testuser) FILER: *************** FILER: UNIX uid = 31028 FILER: user is a member of group softlab (30100) FILER: user is a member of group rally (31042) FILER: user is a member of group testproj (31038) FILER: user is a member of group testprod (31039) FILER: FILER: NT membership FILER: SOFTLAB.LIN\testuser FILER: SOFTLAB.LIN\Domain Users FILER: SOFTLAB.LIN\Gemini FILER: BUILTIN\Users FILER: User is also a member of Everyone, Network Users, FILER: Authenticated Users FILER: *************** Now the user can access the group's files over both NFS and CIFS. Can anyone make head or tail of this? /Leif Nixon

Upgrading Snapmirror-System 5.3.7R3 to 6.0.3
by Phil Hill 22 Nov '01

22 Nov '01

Hi all, we are planning tomorrow upgrading two snapmirrored F740s from 5.3.7R3 to 6.0.3 . Questions: 1. Which system do we upgrade first? ( destination or source filer ? ) 2. Turn OFF snapmirror prior to upgrade? 3. At what time can I restart the mirror ? -- after "vol status -c" tells me checksums are active ? Note: This could last probably two weeks until there are no 5.x snapshots anymore. -- or directly after both filers are up with the new Ontap 6.x ? -- is it necessary to delete all snapshots - to speed up the WAFL upgrade on both systems -- or is it ok to delete just the snapshots on the destination filer ? 4. And is there something else to consider ? I did not find any doku on this. Thanks for help and advise Phil
