Ontap 8.1 performance issue
by Alon Zeltser 26 Jul '12

26 Jul '12

Hi all As a netapp ASP I spent quite alot of my time installing netapp's at costumers site and resolving their issues and I wanted to share my recent experience with 8.1 Usually I try to avoid RC release but until recently the fas22xx didn't gave us much choice Once the 8.1 GA released I felt more free to install this release. but after I started to get performance complains from my costumers I wasn't so sure After investigating some of the complains I felt that they are justified something is off in system I can't put my finger on it but its looks the system don't perform as expected even though the system don't look busy. After opening support cases at netapp one of the engineers told me that they also gets alot of performance cases with this release an even though he can't find a bug that feets with our logs and perfstat he recommend upgrade to 8.1.1rc1 Following his advise after upgrade I saw major performance improvment I mean throughput went up from 70-80 MB/s to 250-300 MB/s and latency also went down The same result occurred on more then one 8.1 system after upgrade to 8.1.1rc1 I saw at least 50% improvment in throughput Today on new system I install I completely skip th GA version an go straight to 8.1.1rc1 So my advice if you on this release and suffering from performance and don't know if you have enough disks or the right controller upgrade first then check Sent from Samsung Mobile

ndmpcopy from 6.x to 8.1
by Jon Bousselot 23 Jul '12

23 Jul '12

Has anyone used ndmpcopy to migrate volumes from ontap 6.5 to 8.1 without going through any intermediate steps? The 8.1 docs say qtree snapmirror doesn't support source volumes prior to 6.5, so I'm looking for success stories on possible alternatives in case it doesn't work as advertised. rsync takes a long long time, but it works fine. This is all linux data, nfs. -Jon

dfpm command assistance
by Scott Eno 23 Jul '12

23 Jul '12

For the couple of folks out there that may actually use the dfpm commands, anyone know how to designate a subnet in the following command? dfpm dataset nfsaccess -w ???.???.???.??? It won't let me use ".0/24"-type notation, so how else could I do it? x.x.x.0?

switching between cluster mode and 7 mode
by Dan Olson 23 Jul '12

23 Jul '12

Hi all, Is it trivial to switch between cluster mode and 7 mode? I understand that the data on the array will be wiped, but are there other caveats to be aware of? Are there any licensing or cost issues to be aware of? Does anyone know what additional hardware is included in the FAS 2240 Cluster mode configuration? I understand there is a switch, potentially multiple switches included in cluster mode configurations.

Thanks Blake. What I like to use the old script for was displaying the list of hosts connected to the filer, especially when I have done data migrations and the admins look to me to tell them which of their hosts are connected. I know I can do this as a one-off but the script is nice as it keeps updating as systems disconnect and connect. --- Scott Eno On Jul 20, 2012, at 6:25 PM, Blake Golliher <thelastman(a)gmail.com> wrote: > Is this script very different from nfsstat -l output on the filer, or > the vfiler as it were? > > When I've used multistore I kept them down to single volume.

You can use ifgrp favor command to manually switch network activity to one interface while your network guys work on the passive inferface switch It will be a graceful transfer rathen then the sudden link break when the switch goes down Sent from Samsung MobileFletcher Cocquyt <fcocquyt(a)stanford.edu> wrote: Our networking team needs to do switch maintenance (hardware and firmware) Each of our 3270 cluster heads is connected to redundant switch pairs - the ifgrp (aka vif) is setup as a single mode: ifgrp create single na01-vif0 e1a e1b Current status (abbreviated for readability): na01-vif0: 1 link, transmit 'none', Ifgrp Type 'single_mode' fail 'default' Ifgrp Status Up Addr_set up: e1b: state up, since 20Jul2012 12:01:50 (00:41:27) mediatype: auto-10g_sr-fd-up flags: enabled favored down: e1a: state down, since 20Jul2012 12:02:21 (00:40:56) mediatype: auto-10g_sr-fd-up flags: enabled unfavored Q: what are the recommended Netapp steps to preserve uptime with the least disruption while the networking folks upgrade each switch in turn? thanks!

recommended procedure for switch maintenance

Our networking team needs to do switch maintenance (hardware and firmware) Each of our 3270 cluster heads is connected to redundant switch pairs - the ifgrp (aka vif) is setup as a single mode: ifgrp create single na01-vif0 e1a e1b Current status (abbreviated for readability): na01-vif0: 1 link, transmit 'none', Ifgrp Type 'single_mode' fail 'default' Ifgrp Status Up Addr_set up: e1b: state up, since 20Jul2012 12:01:50 (00:41:27) mediatype: auto-10g_sr-fd-up flags: enabled favored down: e1a: state down, since 20Jul2012 12:02:21 (00:40:56) mediatype: auto-10g_sr-fd-up flags: enabled unfavored Q: what are the recommended Netapp steps to preserve uptime with the least disruption while the networking folks upgrade each switch in turn? thanks!

Latency reporting
by Peta Thames 20 Jul '12

20 Jul '12

Hi all, I'm a bit new to OnCommand and its many variants so I'm after some advice. I need to start generating regular latency reports for management. I have an idea on what to do, but as dfm has changed so much but I'd like to pick the collective toaster brain. - What do you think is the best level to report on? Lun/volume/aggregate/controller/entire filer? - What's the best means of generating these reports? I don't have Insight Balance, just basic OnCommand manager/perfadvisor/console/dfm/probably100othersIdon'tknowof Thanks, Peta
