15/19 vFilers migrated - 64 bit aggr upgrade ontap next
by Fletcher Cocquyt 09 May '12

09 May '12

So we've reached the point where our 32->32 bit data motion (vFiler migrations) are almost complete - (pending one vFiler stuck in "Migrate Failed" state case, and a previously fun flex clone vFiler) we purposely destroyed the destination (> 19Tb 64bit) aggregates and recreated them < 16Tb to work around 32->64bit data motion incompatibility Next we will initiate non-disruptive 64 bit aggregate upgrades by adding disk (the only currently supported method) Its beaucoup hoops, but we are almost there - our goal is to data motion off all vFilers btw partner clusters to complete our flash cache hardware upgrade thanks Fletcher

SAS port swap.
by Jeff Cleverley 08 May '12

08 May '12

Greetings, I have a SAS stack (plus other FC ds14s) in a FAS60xx cluster running 7.3.5.1. It has 2 quad port SAS HBAs per filer. The stack currently uses ports 6a and 7d on each filer. I need to add a couple more stacks. To make the cabling consistent I would like to move the current 7d connection to port 7a. When I moved the cable from 7d to 7a on one of the heads, it never brought the port online and never saw the disks on that port. I tried the storage enable adapter 7a but it still showed it was offline. I ran various sysconfig, storage show, disk show, etc, type commands to get the system to go find the disks on the new path. Nothing seemed to help. I waited 5 minutes after doing this just in case there was some type of discovery lag, but they never showed up. When I plugged back into 7d, everything is fine. I thought moving to a new port should work. Is there something else I'm missing to make this work? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

User 'root' denied access - missing required capability: 'cli-route'
by Fletcher Cocquyt 04 May '12

04 May '12

I'm seeing this error "User 'root' denied access - missing required capability: 'cli-route'" (on the console) at the cutover stage of vFiler migration under 8.1 GA The vFiler migrations are successful, but this error is troubling for production vFiler migrations which require zero downtime. I opened a netapp support case and posted more details here: https://communities.netapp.com/message/80796 I'm looking to confirm the proper useradmin user->group->role mappings for root in case 8.1GA introduced some bug.

DataMotion for Volumes in 8.1?
by Randy Rue 03 May '12

03 May '12

Hello All, Running 8.1GA on a 3240 and trying to move two vfilers from one aggregate to another (both are 64 bit aggrs). Ultimately I just need to move the root and data volumes for these vfilers. Not finding a wealth of examples on the "vol move" command, not surprising as this is a pretty new feature. http://www.netapp.com/us/communities/tech-ontap/tot-data-motion-1102.html NetApp's blurb says this can be done without interruption, but also talks a lot about when to do the "cutover." They say the cutover can be triggered manually or automatically. But I can't make the "vol move" command do anything but return a usage blurb unless I include a "start" switch. Also, their website claims this can be done nondisruptively. But "vol move start" keeps failing because I have CIFS and/or NFS running. In fact, if I turn them both off it still complains that I have NFS exports configured and that I need to remove them first. Anyone have experience moving volumes from one aggr to another, hopefully live? Randy Rue

Getting a quick "connection refused"
by David Lee 02 May '12

02 May '12

A TCP connection towards an arbitrary high port number (>=1024) on the NetApp seems to return "connection refused" instantly. By contrast, a connection towards a low port number waits for several minutes, then something times out. I imagine this is related to assisting security etc. As part of our transition from our previous non-NetApp fileserver, it would be very useful if we could persuade the NetApp to return a quick "connection refused" on a particular low port number. But we cannot see a way to adjust this behaviour (either for a particular low port or for all low ports). Is this possible? If so, could you point us to the relevant documentation, please? (If it is not possible, we can probably put a workaround in the external application.) -- David Lee

List Administrivia - posts from non-subscribers
by Tom Yates 30 Apr '12

30 Apr '12

At the moment, you have to be a subscriber to post to this list, but if you post from a non-subscribed address, it's referred to the moderators for manual approval. We must be getting famous at the new address, because more and more spam is being received by the list; it now significantly outweighs the legitimate posts referred to the moderators. So I plan to reconfigure the list to simply reject posts from non-subscribers; I expect I'll do that in about a week's time. I'll let the list know when the change has been made. Meanwhile, may I urge people posting to make sure they're posting from the address at which they're subscribed? If you genuinely want to use multiple addresses to post, I'll point out that you can subscribe all of your possible posting addresses, then use the web interface to opt all but one out of receiving list posts (set "nomail" for each of them). If anyone's got issues with this, please email me and the other moderator *OFFLIST* at owner-toasters -at- teaparty.net; I'm open to suggestions, provided they're made before any change. -- Tom Yates - http://www.teaparty.net

Reallocation and VMware
by Peta Thames 29 Apr '12

29 Apr '12

Hi all, I'd like to pick your collective brains about your experiences with reallocate, specifically when reallocating luns under VMware. For background, we're running ONTAP 8.0.1 on a 3170 that's over three years old. I've been going through measuring reallocation, and most of the volumes are over 3. We have no snapshots, and only a relatively small number of volumes are de-duplicated. All our volumes and luns are thin-provisioned, and no aggregate is more than 76% full (most are ~65%). We regularly have huge latency spikes (worst I've seen so far is 5000000ms, and there are far too many to even track over 50000ms daily), and on one filer head, but not its partner, I regularly see disk utilisation go to 100% or more. I'm hoping reallocate will help here. I have a brief note from a NetApp support person who says "It’s very important that you complete the reallocation in the following order: 1:OS 2:LUN 3: Volume". I have two questions about this: - is it absolutely necessary to defrag the OS before you reallocate the lun? I'm sure I've run reallocate without defraging the OS and still seen performance improvements. I'm also assuming that this is only relevant to Windows VMs, not Linux (in our case, Red Hat/CentOS) ones. - if you only have one lun per volume, do you still need to run reallocate on both the lun and the volume? If only one, which is preferable? All advice appreciated. Thanks, Peta

Mixing SAS/SATA DS4243 in the same stack.
by Jeff Cleverley 27 Apr '12

27 Apr '12

Greetings, I know that I can have a mixed stack of SAS and SATA shelves as long as all the drives in each shelf are the same type. I was wondering if anyone has seen any performance issues with this type of mix or if the preferred practice is to not mix them in a stack? I have some shelves to add and it would be very convenient if I put them all in the same cabinet. I just don't want to slow the SAS down with SATA/BSAS traffic on the same bus. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

OS behaviors.
by Jeff Cleverley 26 Apr '12

26 Apr '12

Greetings, We upgraded a pair of 6080s and 6040s from 7.3.3P5 to 7.3.5.1P4 at the first of the year. Within 1 hour of the upgrade, our OpenNMS server started getting timeouts for SNMP polling. We had ~130 per head for the 6080s in the next 2 days. We had 0 in the prior 2 months that I checked. We also noticed the average CPU load for each head went from ~40% to close to 60% utilization comparing December to January. Anytime the cluster is in a failover mode, we get quite a few customer complaints due to slowness. While I can't say for certain we did not have this slowness before, none of us remember any complaints when the cluster was failed before. Obviously trying to run 120% utilization on 1 filer instead of 80% will cause this issue :-) The 6040 cluster did not give the polling errors, but it looks like the CPU load is higher on them also. The load is usually low enough to gracefully cover a cluster failover. I've had a case opened since the first of the year and it looks like we are now out of options and ideas with no explanation or resolution. At this point our plan is to roll back to the 7.3.3P5 OS since it seemed to behave better. Since there is no identifiable problem or solution, it makes us unwilling to jump to a newer OS since we have no reason to believe the issue isn't inherited by later revisions. Rolling back to a known good OS seems to make the most sense. We will roll the 6080 cluster back first and see how it works out before we roll the 6040 cluster. My question to the group is whether anyone else has had a similar issue but did jump to a newer OnTap release that fixed the issues? The vast majority of our data access is via nfs from RHEL5 clients and servers. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611
