NetApp will have support for SDLT in Data ONTAP 6.1.2 which is targeted for release in the November timeframe.

Greetings. I had not seen any running commentary regarding the use of DFM (Data Fabric Manager) on the list. Are any folks on the list using it? What are your thoughts thus far? thanks. Alexei

RE: Anyone out there do backups via a share?
by Honeycutt, Michael 30 Sep '01

30 Sep '01

Well, I wasnt specifically referring to backups. However, I had problems sharing the snapshot dir as a hidden share for faster restores from snapshot. Sometimes it would work, sometimes it will not let you copy the file out with a share error. I had to stop the share and make it visible to get the restores to work correctly. -----Original Message----- From: Jordan Share [mailto:iso9@phantasticant.com] Sent: Friday, September 28, 2001 3:23 PM To: Honeycutt, Michael; Muhlestein, Mark; NetApp List Cc: Benn, Paul Subject: RE: Anyone out there do backups via a share?

The only thing about sharing the snapshot is you may get share errors when trying to pull files out.

Super-sweet. Thanks very much for this pointer. I didn't realize you could create a share of a snapshot. I just did a trial run, and everything works smoothly. Oh, I did have to specify a user:password in the rsh command. This is not indicated in that URL that you sent. The URL only shows "rsh -l root filer-command-here", whereas I had to use "rsh -l root:password filer-command-here".

So, does anyone out there do backups via a share? What I've been doing is mapping a drive to the appropriate place, then backing up from the ~snapshot/nightly.0/ directory. Then I found out that this is quite a pain to restore, since my backup software (Backup Exec) insists on either using an identical tree structure (which fails, because ~snapshot is read-only) or no tree structure at all (as far as I can tell). Is there a better way? It'd be sweet to be able to restore directly to the filer. :) The resources I have are: Treefrog tape library attached to Win2k box with Backup Exec 8.6 (with remote-server-backup license whatnot). Any ideas? I definitely can't use NDMP, or attach directly to the filer, because then we'd need another filer to restore to (which is not a viable option for us at this time. :( ) Thanks, Jordan

Ok I think I get it
by Julius Talbot 28 Sep '01

So, if both filers in a partner pair retain their identities, does this suggest that in performance sensitive environments you would be better off with many small filer pairs than a few large filer pairs? I'm concerned with hotspots and the like. Also, how are disks handled? Can you have asymmetrix configurations with one filer seeing some disks that the other filer doesn't see? For instance filer A would see disks 1-10, and filer B would see disks 6-15? And if this is possible how does one compute the complete disk capacity for a cluster? Can you use the NodeWWN from sysconfig? How could a unique sum of all disks based on the output of sysconfig be done? And thanks again for all your help. I've tried to read the documentation, but it doesn't step through the output of the commands or how to calculate certain things. -- _______________________________________________ Have you downloaded the latest calling software from Net2Phone?

RE: boot volume with no data

That would be nice, wouldn't it? Freeing up 2 36GB drives would be awesome. $5 says it just replaces the floppy disk as a way to boot/load media Just got word our 880 is on the dock. We're leaving tomorrow to steal 3 FC9s from an existing implementation and plug 'em in to the 880, along with 1 DS14 shelf. Can't wait to see the DS14; fiber all the way, baby! Any recommendations where I store the root volume? FC9 or DS14? I'm inclined to store it on the FC9, as it's the most legacy. Come to think of it, am I supported on what I plan to do with my 880? We plan on running a hybrid environment of shelves; FC9s on the FC adapter, and DS14s on the new fiber adapter... -john John Witham Senior Data Networking Engineer Takeda Pharmaceuticals North America, Inc.

If so, is it automagically mirrored to a cluster partner's compactflash for failover? (since an ATA disk wouldn't be visible by both heads). Nice going. ..kg..

RE: NetApp 840 vs EMC Celerra
by Joe Luchtenberg 28 Sep '01

I am interested. Would like to know more about the specific config. #disks/RAID config/# file systems/any tuning/ etc... This could be useful, considering the previously standard benchmark for Unix performance (SpecSFS) has been retired, and the previously published results are supposed to be a poor basis for comparison due to three identified problems. Posted a question to this effect on the NOW Forum for NFS performance, but haven't gotten (to my point of view) a satisfactory answer.
