RE: ONTAP UPGRADE - FEEDBACK REQUEST

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.

Right on the button. I'm not clear on why the date would have been hosed replacing a DIMM, but that appears to be exactly what happened. It got set to 9/5/05 00:00:00 GMT. Wow. I feel a little silly for not even thinking to check that. Thanks for the advice without ", moron" attached at the end. :) -bmr On 15:39 Thu 20 Sep , Dave Barr (????) wrote: > Check the time (clock) on your filers.

snapmirror status / lag
by Brett Rabe 21 Sep '07

21 Sep '07

Howdy. Trivial question for y'all. I have two FAS3040 heads (-01 and -02) in an HA configuration. I have one FAS3040 head (-03) to which both of these are mirroring their data (every 5 minutes). The following is the status output on the backup toaster: mpls-toaster-03> snapmirror status Snapmirror is on. Source Destination State Lag Status mpls-toaster-01-priv:vol1 mpls-toaster-03:vol1 Snapmirrored 00:04:28 Idle mpls-toaster-02-priv:vol1 mpls-toaster-03:vol2 Snapmirrored 17895:54:16 Idle It all works just fine. I'm curious about the Lag time. What exactly does that mean? Why is it "17895:54:16"? It appeared that way after I did a failover of -02 (to -01) for the purposes of replacing a DIMM. Brought it back, did the giveback, and everything is working fine. The mirroring still seems to be working just great ... this is more of a curiosity question than anything, I guess. -bmr

ESX FC Give & Take
by Carl Howell 20 Sep '07

20 Sep '07

I'm troubleshooting an issue we're having with three ESX 3.01 hosts connected to a FAS3050c via Fibre Channel. After a takeover of the filer node that has active VM/LUN's running on it, the following appears in the /var/log/vmkernel file of the ESX host that owns the active VM's: Device vmhba2:0:2 has disappeared but is currently in use and could not be removed. Device vmhba2:0:3 has disappeared but is currently in use and could not be removed. On the other two ESX hosts, this appears in the /var/log/vmkernel file: Device vmhba2:0:2 has disappeared and has been removed. Device vmhba2:0:3 has disappeared and has been removed. Now, the VM's survive the takeover and are still up and running, but if I attempt a giveback, all three hosts lose access to these LUN's and the VM's go down. It appears to me that the ESX host that owns the active VM's has a SCSI reservation to these LUN's and a takeover is not enough to cause it to reset and remove that reservation(even though the paths failover properly). This type of behavior is mentioned in http://www.vmware.com/community/thread.jspa?messageID=752442. All of the timeout values have been verified etc. . . Thanks in advance for the help, --Carl
