RE: SUMMARY: F840 for F740 swap
by Witham, John 21 Nov '00

21 Nov '00

I also completed a F760 for F840 swap this weekend. It sounds like your swap went much quicker than mine. Here are a list of "issues" we encountered: - First and foremost - NETAPP, QUIT PUTTING THE GROUNDING SCREWS ON THE SIDE OF THE FILER! It's _really_ difficult to get that screw loose when you can't remove the side panel!! (EMC Sym on one side, another filer on the other). We had to pull the disk tray above the filer, pull the rail, and be very dexterous to get the things loose. To top it all off, the 840 is in the same chassis! - We had the 2 840s and 6 disk trays included in the order for one of our other locations, everything was shipped there. We then FedEx'd the filers and the disk trays to another data center. The boxes looked like they had gone through Saigon. Dunno if it was out of the box, or because of shipping, but we ended up having a bad motherboard on one of the 840s, it would just reboot without warning after about 10-15 seconds. Thank God for the spares kit! - We added 3 drive trays to each filer. 2 of the drive trays shipped with an OS. Luckily, we put those 2 trays in the same cabinet. After a major annoyance, we booted with the floppies to each tray, destroyed the volume, and drudged through. - Of the 6 trays we received, only 4 fibre cables were in the boxes. Ugh! Only the box with the bad motherboard ran a parity recalc, presumably because we pulled the NVRAM battery and card when we swapped mobos. Both boxes made us do a Disk_FW upgrade. All in all, it went really well, even with the minor headaches. I was fortunate enough to have a NetApp PSE on hand, and he had the situation well under control at every turn. -john John Witham MCSE, MCP+i, A+ Systems Engineer Takeda Pharmaceuticals America, Inc.

F760 and Unisys OSM3000 shelves
by marcotte＠panix.com 21 Nov '00

21 Nov '00

I have a large quantity of Unisys fibre channel disk shelves (well over a terabyte), and I was hoping these would work on a NetApp F760. Specifically, these are: Unisys OSM3000flr - Fibre Channel disk shelf They have 4 DB9 connectors (two loops), and dip switches to select unit IDs 0-7. UNISYS 006073ST19171FC - 9 GB FCAL disk. Each shelf contains 8 of these. These are basically Seagate ST19171FC disks, and could probably probe that way with an appropriate firmware download. I believe that OnTap supports the drives themselves (both as Seagate and Unisys), I don't know what magic NetApp does with their shelves though. If I can't make these work on a NetApp, I'll be forced to attach them to a Solaris box. :( Thanks! -- - Brian

I would like to say some specific note on the length of card: Please use the System Configuration in NOW, and DON'T count on plain logic of: "hey this card is long so it should fit here...". The only supported configuration (and maybe a few more) are the ones in these tables, and sometimes (like SCSI dual-port card X2023) a long card actually should go to a 32bit slot because an engineering reason....

F840 for F740 swap
by Matt Phelps 21 Nov '00

21 Nov '00

We just got our new F840 (it has an UGLY *gold* faceplate by the way). It will be replacing an F740 straight away. My questions have to do with swapping an Intel NetApp for an Alpha NetApp while keeping the same disks. Has anyone done this yet? Aren't the Ontap system files different binaries? What should the sequence of events be? Our plan (so far) is this: 1. Shut down the 740 2. Boot from floppy of old OS (5.3.6R1) 3. run a wafl_check (we want to do this anyway) 4. still using the 740, upgrade using the 537R1_sysfiles_i.tar file (I'm presuming these Intel binaries won't work on an Alpha NetApp) 5. on the 740 console, run the "download" command (will this work now?) 6. disconnect the 740, pulling it's Gigabit ethernet card 7. Put the gigabit card in the 840, connect it up 8. Turn it on and it will work (right?)!! Any thoughts, comments, will be appreciated. -- Matt Phelps System Administrator, Computation Facility Harvard - Smithsonian Center for Astrophysics mphelps(a)cfa.harvard.edu, http://cfa-www.harvard.edu/~mphelps

Problem with disk
by Marcin Kuzniacki 21 Nov '00

21 Nov '00

I've two 740 filers. In one of them one disk failed. I removed broken disk and inserted to the second filer. I expected this disk as spare or broken, but filer doesn't recognize disk. I want to make disk_zero, but I don't want to do that on filer where disk failed - don't ask me why ;-). Marcin

logging with etc/syslog.conf
by Todd C. Merrill 18 Nov '00

18 Nov '00

Last I recall, the syslog facility of ONTAP didn't work so well (probably 2-3 years ago) or the granularity was insufficient to make it useful. It seems ONATP is logging a lot more these days, and the messages file is so full of "crap" (i.e., informational messages) that seeing real problems or security issues requires me to write an external perl script, albeit a simple one, to parse the logs. If anyone is using etc/syslog.conf, would you please comment on how well or not well it works for you? Maybe include yours if you have a particularly interesting or clever filtering scheme? And, NetApp, can you please fix this? The second line of these related messages doesn't contain a timestamp. Really fools up anything that expects it: Sun Nov 12 17:56:50 EST [Java Thread]: TimeDaemon: timed: adjusting time: filer thinks time is Sun Nov 12 17:56:50 EST 2000. Time reported by time server time is Sun Nov 12 17:56:50 EST 2000 (skew -0.071 secs). Thank you. Until next time...

RE: Backup Exec on 760 NT filer
by Walsh, Warren (MN65) 17 Nov '00

17 Nov '00

We're happily using Backup Exec 8.0 in our NT/2000 environments (and NetBackup for the filers). There are agents, some licensed separately, some included with BE, for specific applications. IE, there are agents for Exchange and SQL that work with the MS APIs to flush the logs and perform an online backup of the database. There are accelerator agents available for NT, 2000, 95/98 platforms that have two benefits. In the case of a differential or incremental backup, the agents scan the local drives to determine what files need to be backed up. The agent also compresses the data as it is sent over the network to the backup server. The agent typically improves performance by 30% on our 100Mbit switched network. There are agents for the Mac and some UNIX flavors included with the advanced edition. A Novell agent can be purchased as well. A new requirement with Backup Exec 8.x and Windows 2000 is that Windows 2000 systems being backed up remotely must have the Backup Exec Windows 2000 agent to fully protect the "system state". I think this means the new Windows 2000 specifics like AD. There's no reason you couldn't use Backup Exec to backup a CIFS-enabled filer over the network. (You could probably even mount the NFS export on a UNIX server, and use the UNIX agent.) Backup Exec would treat the filer's UNC like any other NT share - if the Backup Exec account can access that share, it can back it up. Performance would be my big concern - Backup Exec doesn't stream or interleave jobs. Throughput over the network is typically 20-30GB/hour. You could run multiple jobs to multiple tape drives - i.e., backup vol1 to drive 1, vol2 to drive 2. I'm not sure how it would handle things like archive bits or UNIX style file permissions. -warren -----Original Message----- From: Patrick Lee [mailto:pat@patlee.org] Sent: Thursday, November 16, 2000 10:46 AM To: Benn, Paul Cc: toasters(a)mathworks.com Subject: RE: Backup Exec on 760 NT filer At 19:14 11/06/00, Benn, Paul wrote: >The latest versions of Veritas BackupExec (8.x) supposedly now require that all >backup clients have a backup agent installed.

RE: Backup Exec on 760 NT filer
by Tom "Mad Dog" Yergeau 16 Nov '00

Databases generally back up much faster than file systems because they're, well, databases. They can stream data faster and you're also backing up one or two files instead of thousands to millions. They often compress much better as well and you see improvement in the transfer rate because with one drive your tape drive is the limiting factor. By compressing the data you get more data on to the tape in the same amount of time (i.e. if you're using DLT, with 5MB/sec native write speed, and you can compress 1.5:1, you're actually writing 7.5MB/sec). Backup Exec does work fine for backing up CIFS filers, but it all depends on how much data you have to back up. If you're backing up a couple hundred GB, it'll probably work. More than that, you probably want a more scalable solution (e.g., multiple tape drives spinning during a backup over GbE, or local attach NDMP backups).

A couple of us have already put out feelers for 5.3.7 and I've only seen limited public response. We've been running it in the lab and limited production for about two weeks now with no problems. So far everything we've heard from others has been positive. 1) Any customers with active bugs open on 5.3.7? 2) Anybody having problems with Veritas NBU + 5.3.7? 3) Any NetApp folks willing to say when 5.3.7 will be recommended?

Sometimes people do indeed get carried away by emotion. What *is* relevant about my response posting (look at the subject:) is that Exchange doesn't and won't support NAS. This effects customers of NetApp, but also EMC, Microsoft, MTI, Compaq, IBM, H-P, etc.... That I happen to work for EMC was NOT relevant with respect to my initial response. But, hey, some people judge one's posting on where the poster gets it's salary and not what experience, knowledge the poster can contribute.

Peter, The fact about your employment is relevant for the reader to evaluate your comment. I give more credibility to comment from "neutral" party. Comment from competitor gets lowest credibility.

Anyone seen this? .snapshot missing from readdir() even for mount point
by Chris Thompson 14 Nov '00

14 Nov '00

I was prompted by trawling over Bugs Online to open a call with NetApp about the following problem, which I've known about for a year or more. The call isn't making much progress (we won't go into whose fault that is ...) and as the whole thing was really a request for information ("did you know about this infelicity? is it going to be fixed some year?") I can't conscientiously exert much pressure. But I can waste your time asking whether you've observed the same effect, can't I? :) As I am sure you are all aware, although ".snapshot" can be looked up in any directory, it is only visible to readdir() in NFS mount points (5.3 System Administrator's Guide, p.406: "Actually, the .snapshot in the mount point is "real" to make the pwd command work ..."). The problem is that sometimes ".snapshot" isn't visible to readdir() *even* in mount point directories. This seems to happen only in directories with more than one 4K block (it's notable that "ls -f" shows .snapshot coming after the first block's worth in such directories, if it shows up at all), and rather rarely even then (2 out of over 150 user home directories of >4K that I looked at today), but as long as the directory isn't tinkered with the state remains the same. I've observed this with several OnTap 5.2.x & 5.3.x releases, and several different Solaris releases as clients. It *could* be an NFS client implementation problem, I suppose, but I don't think I believe that. Does this sound familiar to anyone?

CIFS connections

Upgraded to an F840 running 5.3.7 this weekend. messages file keeps showing oplock break timeouts, and a very tenuous connection to *any* domain controller it tries to connect to. Clients seem fine; DC's seem fine; no apparent problems elsewhere. Thoughts?

RE: LSA Errors

We are running 5.3.6R2 on this filer. We were seeing the errors before we upgraded and we are continuing to see them after upgrading to 5.3.6R2. Also, the errors will start on a particular filer, I'll see a ton of them for a number of days, and then they disappear just as quickly as they started. I've looked on the logs on the Domian Controllers that the filer is connecting to, but they aren't reporting any errors. ??? -Lella -----Original Message----- From: Paul Lupa [mailto:ra5507@email.sps.mot.com] Sent: Friday, November 10, 2000 3:40 PM To: lella.r.bennett(a)lmco.com Cc: toasters(a)mathworks.com Subject: Re: LSA Errors Check your version of OnTap, I believe this was corrected in 5.3.6 (be sure to go to 5.3.6R2). I had the error for a long time, (along with "access denied" errors from the clients) and it went away with an upgrade.
