Fabrica metro cluster with ds14mk4 and ds2246
by Milazzo Giacomo 16 Jun '14

16 Jun '14

Hi everybody Can fc path coming fm atto bridges share the same iinitiators on the fas used also by the fc disk loop? Following an head swap fm 3160 to 8040 with 8.2.1 I've zoned a store zone with the fc port used by atto and the 4 initiators on 8040. Exactly as done with port coming from fc loops The fas starts to message a lot of timeouts and errors related to the sas disks then panic Of course the fc loops are on fc ports forced at 4 Gbps while the at to negotiate at 8. Can be this the.issue? Should I.have to.use a separate hba just for sas and another one for fc disk loops? Reading docs this don't seem a requisite. Regards Inviato da Samsung Mobile

snapmirror, flexclone and inconsistent volumes
by David Byte 13 Jun '14

13 Jun '14

Well, this is a fun one. I do some work for a shop from time to time that has a filer that is no longer under a maintenance contract. The other day, one of the guys saw condensation on the light fixtures and turned off the A/C for the room and left for the day. Needless to say, bad juju and a triple disk RAID failure.. So here we are today, I've managed to get the RAID back online (disk unfail, WAFL_check/wafliron) and have purchased some extra drives to replace the now non-existent spares pool. Here's the challenge. The primary data volumes were replicated off site on a nightly basis with snapmirror. There is a flexclone of one of the volumes where important data had been updated (don't ask) that had not been replicated. I have all the volumes online, but get errors on the console about inconsistencies when reading from all of them (there were severe media errors.) What I want to know... Is there some way to use snapmirror to bring the backing volumes back to a consistent state (including the snapshot backing the flexclone) and hopefully save their flexclone volume as well? Thoughts?'

Need Help - 100% ANY CPU
by Kalra, Manish 11 Jun '14

11 Jun '14

Hey Guys, I had an issue with one of my 7-mode filers (ONTAP 8.1.2) where all of the CPUs were 100% and there was no indication of any volume doing more IOs. It took down everything on the filer and DBs crashed. During the issue the output of wafltop show -v cpu: aggr_sas02_64:prod_volume1:nfsv3:WAFL_READDIR: consuming 300% CPU When we checked on the hosts mounting this volume we found out that there was one volume "deploy01" which was migrated to new c-mode filer but the mount was not fixed on those 3 hosts. So the NFS stack on those 3 servers was hung. The question now we have is: 1. Why would NFS stale on 3 hosts took down the filer? 2. Is there a BUG around this situation which someone has experienced before? Any help/clues would be greatly appreciated. Manish

Oracle Volumes and Compression
by Peta Thames 11 Jun '14

Hi, I've read that compression works well on volumes hosting Oracle DB data, but I haven't seen it in use anywhere in the wild yet. Is anyone using compression, and if so, what have been your experiences? Cheers, Peta

I don't think you want that, especially also for NPIV. You need an F port or an N port, not an E port. E ports are expansion ports, for ISL (inter-switch linking), and connect two switches together. F ports are fabric ports, and are used for point-to-point connections (hosts, storage systems, etc). N ports are node ports, similar to F ports, used for point-to-point or switched fabrics. For you, Fx or G port types should also work, and I think Brocades have U ports too, but I'm not too familiar. -Adam On Mon, Jun 9, 2014 at 9:35 AM, Alexander Griesser <ag(a)anexia.at<mailto:ag@anexia.at>> wrote: Hi there, I’m having a hard time currently connecting my new FAS8020 to our existing fabric – the FCP ports just won‘t get online and I’m not sure where exactly the problem is and how to debug that since I’m more the NAS guy not having much practical experience with FCP configurations, so here’s the deal for all of you who are wanting to help.

Reallocate in ONTAP 8.2
by Peta Thames 05 Jun '14

05 Jun '14

Hi, Reallocate has been like a magic performance-improving wand for me in the past (and thanks to members of this list for that). However I believe later versions of ONTAP have lessened the need for regular reallocation. Is that the case, or is it worth running regular reallocate measures? What's people's experience with ONTAP 8.2 and reallocation? Cheers, Peta

Backing up NetApp running CDOT with TSM
by jamesr 03 Jun '14

03 Jun '14

All, I've done a lot of browsing around of both NetApp resources and TSM resources and can't find an answer to this. This has lead me to this mailing list! We are currently deploying a NetApp FAS 8040 with around 500TB of disk behind it and we use TSM as a backup solution. Does anyone have a similar setup? How are you backing it up with TSM? Do you have configuration notes you'd be willing to share? We've looked at Snapdiff but this is unsupported with CDOT presently (http://www-01.ibm.com/support/docview.wss?uid=swg21633171) So I think we are looking down the NDMP route - however I'm not sure of exact implementation details of this... do we need to dedicate tape drives to this? What are its limitations? How do file restores work? etc. etc. etc. Anyone that can provide any assistance would be greatly appreciated. Cheers.

SAS controller limitations.
by Jeff Cleverley 01 Jun '14

01 Jun '14

Greetings, A while back there was a known issue with the SAS controller. Each chip that controlled 2 ports would only address 128 devices. That included shelf controllers so technically 5 ds2246 shelves would exceed the limit and could cause some slowness. I was told that they changed this behavior in 8.1 and possibly upgrading the firmware, so that it only kept active devices in the list. I was told those devices would be removed when not active and so there was no need to keep the smaller shelf limit. Is this the case, or do I still need to try to limit each chip to 5 shelves or less? I'm running 8.1.2P4 and the cards are running 01.11.00.00.

Oracle access and backups
by Jeff Cleverley 28 May '14

28 May '14

Greetings, My Oracle experience with and without NetApp has largely been non-existent. Please bear with me on this. All of our current DBs are on dedicated servers with locally attached storage. One of our groups has a 6280 cluster running 8.1.2P4 7-mode. They want to look into using iscsi to a new 11.2 Oracle server. The cluster can get pretty busy at times so I'm not sure Oracle NFS will work in this case. The questions are largely about backups and DR. I'm curious about how most people choose to back this up and how to recover for that solution. I know there are lun copy options, snapmanager/flex clone options, etc. We're very open to manual scripting and custom solutions. Backups would most likely go to a NearStore, and the DR would be a second server connected via iscsi also. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611
