Omniback -Reply
by Timothy Cook 22 May '00

To backup a filer from omniback, just nfs mount the filer and give the verbose path to omniback. ********** DON'T FORGET TO EXCLUDE THE .snapshot directory!!******** Otherwise your backup will NEVER complete. >>> "Uros Lampret" <uros.lampret(a)ourspace.si> 05/22/00 03:03am >>> Does any body know how to backup a filer with Omniback. We use Omniback and now testing an F740. Uros

software distribution with NDMPcopy/SnapMirror over WANs?
by Thaller Horst (MDCA Villach) 22 May '00

22 May '00

Who has experiences with software distribution/syncronisation over WANs with NDMPcopy or SnapMirror? We have a software pool at our master site, where we maintain our software (~ 500 GB) and then we distribute the changes to our client sites. Our actual rcp/ssh-based solution has several drawbacks: * No automatic syncronisation * Transfer of whole sw-packages only * Only Unix-packages supported (no NT packages) My idea is to do this job with NDMPcopy or SnapMirror, but I have a lot of questions: Can I export (ro) the mirrored volumes? (NDMP, SnapMirror) It´s possible to tunnel NDMP/SnapMirror with ssh? Can I mirror more than one site with SnapMirror? Cascaded distribution? Is there a commercial product? best regards, Horst Thaller Infineon Technologies Microelectronic Design Centers Austria GmbH Design Center Villach Siemensstrasse 2, A-9500 Villach Tel. ++43 4242 305-6212 Fax ++43 4242 305-6389 email: Horst.Thaller(a)infineon.com internet: www.infineon.com/ezmvi

Wiping and setting up a system.
by Shaun Erickson 19 May '00

I would like to destroy all volumes on an F330 (with four shelves, fully populated with 4Gb disks), and then create a single new root volume and install 5.3.5R2 (which *does* run on an F330). I'm sure I can destroy the existing volumes (I'm good at destroying things), but it's not clear to me how to then install Ontap onto bare metal (I've only ever upgraded a filer before). Is there a simple recipe for doing this? TIA, -ste -- Desk: (908) 582-7629 Pager: (800) 756-1133 Cell: (908) 672-6456

Neato quickie way. Get to an OK prompt (via halt or Ctrl_C in RAM count) Enter: setenv floppy-boot? true reboot It will as if you want to floppy boot when it locates drives..enter a y or an n..if you dont..it'll just sit there forever.*** You get your 5 item menu, enter on re-init drives choice. At completion, it will walk thru a full setup session like new. Now halt filer. Enter: unsetenv floppy-boot?*** (dont forget..or reboots will sit forever if you dont catch it) reboot All done. Save you what feels like ages in booting from floppy. (This only works if you have good boot images on disks to begin with) -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Friday, May 19, 2000 1:18 PM To: ste(a)research.bell-labs.com; toasters(a)mathworks.com Subject: Re: Wiping and setting up a system. > Is there a simple recipe for doing this?

Pushing the limits
by Jeff Stampes 19 May '00

19 May '00

So we use a F760 for compiling our software....it's a demanding environment, and up until now, NetApp systems have been adequate for us As I've been refining our build process though, I've continuing optimizing it to the point the 760 may become our bottleneck. It seems to be running at about 50-60% of CPU most of the time, with peaks like: CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 98% 4243 6 0 6365 7367 10648 15352 0 0 3 74% 4515 1 0 11902 8348 3592 44 0 0 3 100% 4644 2 0 9472 11021 7763 8088 0 0 3 88% 4307 0 0 9223 9463 7023 10938 0 0 3 100% 5606 0 0 8870 9185 6048 11368 0 0 3 75% 4884 4 0 8622 13913 4032 2432 0 0 3 100% 5717 6 0 6777 10372 6700 11488 0 0 3 I don't knwo when I need to worry....so I have two questions: What stats will cue me into a problem related to overload? What are the limits of CPU/Net/Disk use I should stay under? Provided I find a way to drive an F760 into the ground, any suggestions for a next step? -- Jeff Stampes -- Xilinx, Inc. -- Boulder, CO -- jeff.stampes(a)xilinx.com

The "root"-option is more secure, but this setting has one big drawback: You cannot use netgroup names with the -root option and you can specify only 256 host names! If you have only few machines, the -root option is the better choice. In large server farms with more than 256 machines that are running CDE+dtlogin (XDMCP) the -root option will not work.

Yikes! Both are very insecure choices for a solution!!! The correct answer is to simply export the home directories with root access for those machines that are running CDE that they are logging in through. Bruce

SQL Server 7 with data files on toaster?
by Colm Buckley 19 May '00

19 May '00

Hi - Another request for success or horror stories; does anyone on the list have experience with running MS SQL Server 7 using a toaster to store the data (as described in http://www.netapp.com/tech_library/3042.html and http://www.netapp.com/tech_library/3044.html)? One possibility being looked at here is to run a database from something like a Dell PowerEdge 8450 with the data files on an F720 or F740. I'm aware of the advantages the toaster will bring in relation to backup, snapshots etc, but I'm interested in how the performance of such a setup would compare to, say, attaching a big LVD or Fibre RAID5 directly to the server. Any comments?
