RE: Y2K: Any one rolled a filer forward & backwards?
by Garrett Burke 23 Apr '99

23 Apr '99

Hi Ozzie, If there was a problem with going back then I'd end up restoring from tape which would probably result in downtime during business hours. Checking with others at least gives me some confidence that I wouldn't end up having a conversation with management if I hadn't checked which would go something like: Mgt: Why did you do it? Me: Y2K test Mgt: Has anyone else done it? Me: Don't know, didn't check Mgt: What do you mean you didn't check? Me: (gulp) Mgt: Better start printing your CV out! Me: can't, it's on the filer which has crapped itself! 8-) You get the picture. Many people didn't expect the Y2K problem either. 8-) GB > ---------- > From: Ozzie Sabina[SMTP:ors@cimedia.com] > Sent: 21 April 1999 17:56 > To: Garrett Burke > Cc: 'toasters(a)mathworks.com' > Subject: Re: Y2K: Any one rolled a filer forward & backwards? > > > I have done this and then reset it with no problems (I'm not sure why > you'd expect any). > > (This was with the 5.3 release) > > Oz >

Yes, Dave, but not to put too fine a point on it, this is the same thing that has been said by some employees and customers for years. I'm sure you're sincere, but I think people so far have found Netapp's progress in this area less than satisfying. There has been some, and the classes are a good step, but a lot more should be done. Saying "we're trying to get our arms around this problem in engineering" lacks a little credibility when you realize that you've been saying the same thing for 3-4 years. It might be more honest to say that "we decided to spend that time and money on more revenue-enhancing engineering projects" and that's a sound business strategy, but let's not pretend that Netapp has only now suddenly discovered this issue and is trying to come up with the best solution. Sorry for being a little critical; I rarely am on this list, but you hit one of my hot buttons. :) Bruce

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...

I'll file it under "emergency things I hope I > never need to know". :) Presumably he means "for the purposes of getting at that interactive menu before the filer boots up all the way." 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

Have you seen the nice black polo shirts? My sales rep still owes me a couple, but I'm pretty sure he's avoiding me. I left him voice mail asking how much trouble it would be to return our cluster and he had our StorNet VAR call me. Very disappointing. Guess I can't really blame him. He made the mistake of showing up at my office last Feb after a couple of NetApp delivery mix ups (involving said cluster) which cost me several hours on a Friday night and another couple on a Monday afternoon (they knew about the mix up Thursday - didn't tell me 'til Monday). I had our VAR warn him I didn't want to talk to him, but... >subdued for a corporate freebie.) Last I heard they decided to pocket the >money they were spending on the jackets and the class docs are still very >weak. They should also put the class docs onto the web somewhere because Very weak. I'd have settled for a Table of Contents -- an Index would've been great. The instructors were good. Too bad I don't have a phonographic memory. They did do a good job of answering any odd questions I could come up with. >there are times when the docs aren't handy and I need to remember if it is >26/7 or 28/7 that fries my disks... Not sure about putting the docs on the web. I think that's asking for somebody to trash their filer and blame NetApp for showing them how. 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. jason

It used to be covered in the NTAP 202 class (if you took the class hunt around in the binder full of PowerPoint slides they called a book for "prev_cp - boot from prior consistency point" -- they should've spent more money on books and less on leather jackets) in the Special Commands Section. This worked with a 4.1.x boot floppy in class, not sure about the 5.x boot floppies. As I recall it was for recovering from a severely fubar'd filesystem. As for the date flipping, I have two F740s which aren't doing anything until I get patches to 5.3D2 (maybe Friday last I heard) to make cluster failover stable, so I'll mess around with it and get back to the list. The only issue I can imagine would be some NFS clients getting upset when time "goes backwards" on the server. jason >-----Original Message----- >From: owner-dl-toasters(a)netapp.com >[mailto:owner-dl-toasters@netapp.com]On Behalf Of Garrett Burke >Sent: 21 April 1999 12:17 >To: 'toasters(a)mathworks.com' >Subject: Y2K: Any one rolled a filer forward & backwards? > > >Hi All, > >As part of my Y2K testing I intend rolling the date forward on my filer >(F230, currently 5.2.1, NFS & CIFS) to just before midnight on the 31st and >then watch it as it ticks over midnight.

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?
