I was wondering if, with IIS 5, the "Pass Through Authentication" problem was solved. This is in reguards to http://www.netapp.com/tech_library/3078.html (Integrating a NetApp Filer with Microsoft IIS 4.0) Thanks! -Mathew Mathew Anderson Systems Administration NM Technet Oso Grande Technologies, Inc. mathew(a)nm.net mathew(a)osogrande.net

For the record, I used ndmpcopy to migrate from a F230 to an F740, and had zero problems with it. -- Mike Sphar - Sr Systems Administrator - Engineering Support Services, BOFH, GWP, MCP, MCP+I, MCSE, BFD -----Original Message----- From: John Stoffel [mailto:john@casc.com] Sent: Tuesday, August 29, 2000 7:02 AM To: Cliff.Dobbs(a)arm.com Cc: Premanshu Jain; toasters(a)mathworks.com Subject: Re: Splitting large volumes Cliff> I've decided not to use ndmpcopy as a colleague of mine had an Cliff> absolute nightmare with it when he moved from SCSI to FC-AL. Can you go into this in more detail, since this is exactly what I'll be doing when I migrate from an F520 to an F740 sometime in september/october timeframe. From the looks of things, nmdpcopy should do a great job, but the more details of people's problems that I get, the happier I am. Thanks, John x27548

Present Backup scheme : Spectra Logic Tree frog's attached directly to 740's running dump scripts. I am looking for a solution which can smartly backup 3 TB of data split into several 300 GB volumes on two 760's / 840's (Proposed) . Would welcome suggestions/Comments on the following: Backup library supporting SCSI/Fibre Channel. Better options compared to Spectra logic . (AIT ones) Backup management software - Netbackup/Legato/Workstation Backup server Hardware - SUN box optimum configuration.

Netapp snapshots & reserved disk space
by Richard 29 Aug '00

29 Aug '00

I was having trouble setting the snap reserve to 0% on our mirror, it keeps on giving dumb df output, as it has used over 100% of the disk? snap reserve: volume vol0 is snapmirrored, operation not permitted Any idea how to do this? Richard

If your data is in great big lumps then a vol copy is probably your fastest solution. --- This will not work as vol copy requires an equal or larger sized volume to copy to.

Completely shut off snapshots & reserved disk space
by Pesce, Nicholas (FUSA) 29 Aug '00

29 Aug '00

Many people replied to my question about turning off snapshots. I guess it comes down to it, which method not only turns off the snapshot, but also turns off the systems reserving of disk space. (I know if I manually set it I will be ok) but does the command snap sched vol0 0 0 0 do it or does vol options <volume name> nosnap on I just don't want to have turned off snapshots, but still have the filer reserving space for them (I know this sounds kooky but I don't know if the microkernel will automatically save the space reguardless.) -----Original Message----- From: Summers, John [mailto:John.Summers@netapp.com] Sent: Tuesday, August 29, 2000 6:36 AM To: 'Pesce, Nicholas (FUSA)' Subject: RE: Completely shut off snapshots Hi, From the filer type snap sched vol0 0 0 0 Repeat for each volume.

Re: Splitting large volumes

This is very interesting to me, as I am about to do almost exactly the same thing. We have (don't laugh, please) a single 700GB volume which I want to split in to smaller volumes. To do this we have purchased a new 760 with 8 shelves ( we need more capacity anyway). What I plan to do is use rdist or rsync to copy the data from the old volume to the new volumes. Once the initial (level 0 ) copy is done I will keep up with daily incrementals until such a time as we can arrange a short down time to do a final copy and then re-rack the shelves to split them across the two heads. Hey presto. I've decided not to use ndmpcopy as a colleague of mine had an absolute nightmare with it when he moved from SCSI to FC-AL.
