Jeremy I suggest you consult this weeks posts on Dave Hitz blog (NetApp founder) and people's comments.

We have about 150 VMs across 12 servers at the moment sitting on an IBM DS4500, but I just got my budget approved to buy a nice 3040 cluster. For ease of backup/restore/DR I really would like to use NFS instead of FCP/iSCSI but I don't know what the performance impact will be. Any comments/experiences?

Keeping CIFS from autostarting
by Nils Vogels 26 Sep '07

26 Sep '07

Hi! Is there any known way of keeping CIFS from autostarting upon reboot, once CIFS has been configured? Greets, Nils -- Simple guidelines to happiness: Work like you don't need the money, Love like your heart has never been broken and Dance like no one can see you.

Time issue
by David McWilliams 26 Sep '07

26 Sep '07

I'm have weird stuff going on, it seems like it may be related to the timezone thingy, but I can't think why. We have a FAS250 running 7.0.4. Timed is configured and is pulling the time from the domain controller. The times appear to be in sync (confirmed in the messages file). We cannot mount the shares, it refuses due to the times being more than 5mins apart. The timezone is being reported as EST. When we changed the timezone to US/Michigan and rebooted. It now reports the time as exactly one hour ahead and the timezone is EDT. Right now I have disabled timed and set the time manually - all is well... for now. Does anyone have any ideas? -- Sláinte, David Get a safer, faster, better web browser @ http://www.mozilla.org/products/firefox/

RE: ONTAP UPGRADE - FEEDBACK REQUEST
by Borzenkov, Andrey 26 Sep '07

As you have clusters, I would recommend first updating to 7.0.6 and then – if required – to 7.2.3 or whatever version is available at this time. Then both of them are NDU. NDU between major releases are supported first starting with 7.2.3 and minimal base release is 7.0.6. Personally I do not see any point jumping through 7.1 additionally. Otherwise update from 7.0.4 directly to 7.2.3 was quite straightforward.

we do not utilize CIFS and we have no non production filers to verify/test on :) NDU works for us but yes i agree with you on all points here. -- Daniel Leeds Manager, Storage Operations Edmunds.com -----Original Message----- From: Scott Miller [mailto:Scott.Miller@dreamworks.com] Sent: Tue 9/25/2007 3:24 PM To: Leeds, Daniel Cc: Kennedy, Jeffrey; Borzenkov, Andrey; philip.boyle(a)eircom.net; toasters(a)mathworks.com Subject: Re: ONTAP UPGRADE - FEEDBACK REQUEST I'm with Jeff. A reboot takes less time that failover/failback, and I'd rather have CIFS shares disconnect and re-connenct just once. Rather than NDU, I upgrade both heads and then reboot them at the same time. After having tested the new release on non-critical filer resources, of course ;-) reboots occur during non-peak times or during scheduled maintenance windows, when possible. -skottie Leeds, Daniel wrote: > > NDU is highly valuable when you are running 24x7 environments with live > active data.

Number of mailbox disks with a SyncMirrored root volume
by Nicolai E M Plum 25 Sep '07

25 Sep '07

Hi If I have an active/active (non-Metro) filer cluster, and I use SyncMirror to mirror the root volume of one filer, will I end up with mailbox disks in both plexes, or are the mailbox disks only in one plex (leaving me with a problem if that plex goes away completely)? Online documentation on this is not entirely clear. Would someone who has a SyncMirror setup be able to have a look at their system and answer this definitively? Nicolai

Coincidentally, just this last weekend I upgraded an FAS940 from 6.5.5 to 7.2.2, as well as two FAS3020s from 7.0.5 to 7.2.3. (There wasn't a specific reason for doing 7.2.2 on one and 7.2.3 on the other, it just worked out that way because I talked to two different Netapp support staff about the different servers.) All the updates went completely painlessly and smoothly. I was a little concerned about the big jump from 6.5 but have not as yet discovered any problems or interruptions in service from the update. One thing that I think helped the update go smoothly is this time I contacted Netapp support and requested Upgrade Plans for each server, which I'd never done before. (I've just historically done the upgrades myself without help.) I was especially concerned with the 3020s because there were several firmware updates to apply and I wasn't entirely sure what the correct order should be. Netapp provided me PDFs of fairly detailed instructions for the upgrades. You can also have them provide a Downgrade Plan in the event of problems. I highly recommend taking advantage of that very helpful service, even if you're fairly familiar with he process. (It's also nice to have an official plan already drawn up to file with the Change Control teams.) -- Michael W.
