Do you know an easy way to unset floppy-boot? on a running machine, without halting back to `ok '? If there isn't a way at the moment, I recommend that NetApp implement something a la Solaris' ``eeprom'' command, which allows modifying OpenBoot environment variables, and is really handy when you don't want to take a machine down to change stuff, or you can't get to the console due to unforseen problems (such as when you terminal concentrator locks up that port :( ).

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

23 Apr '99

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. So far, so good. The issue I have (assuming the filer is Y2K compliant!) is rolling it back again. Has anyone rolled their filer forward and then back again to put it back into production? Were there any glitches? There will be files that will have modified dates in the future, but these can be a copy of some production data which can be deleted after the test. GB

Another item that comes to mind is your /etc/syslog.conf (assuming that you have one) and other dynamicly read files. One would hope that the timers used to check this stuff actually use incrementals , not absolute time values - that is set a timer , count down to 0 when you reach 0 check file x and not check the clock every second and at 01:45:30Z01Jan2000 check the status of x. Otherwise when you set your time back, these dynamic files might not be read for some time B-}( ----- Stephen C.

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...
