updating disk qual files on many controllers
by Scott Eno 05 Aug '13

05 Aug '13

Hi, I've got an environment of 30+ controllers, some with NFS licensed and some without, but all with CIFS. I'm trying to figure out a way to push drive qual files (and eventually the firmware files) to all the controllers without going one-at-a-time (batch vs. by hand). 30+ means I can't mount them all via CIFS at the same time, and with half of them without NFS licensed I can't mount them via NFS to, say, a linux host. I was looking into using DFM to push the files to all the controllers, but it doesn't seem to work with anything but the config files it can pull off the controllers first. Anyone have a favorite method?

Recommendations for adding new bigger disk shelves to existing system
by Alexander Griesser 03 Aug '13

03 Aug '13

Hey there, I just got two new DS4243 450GB 15k SAS Shelves and am about to add them to our FAS3240HA. Right now, 4 DS4243 300GB 15k SAS disks are attached to this HA pair, 2 shelves for each controller. Since 300GB disks cannot be purchased anymore, we got the 450GB shelves and I'm reluctant to just "throw away" about 5TB of usable SAS space by downsizing the 450GB disks to 300GB when adding them to the existing aggregates, or does this only apply to RAID groups? So if I create new RAID groups in the existing aggregates, will I then be able to use the "full" [0] size of the 450GB disks? Thanks, [0] After rightsizing and all other nice things NetApp does to the full capacity of the disks :) Alexander Griesser System-Administrator ANEXIA Internetdienstleistungs GmbH Telefon: +43-463-208501-320 Telefax: +43-463-208501-500 E-Mail: ag(a)anexia.at<mailto:ag@anexia.at> Web: http://www.anexia.at Anschrift Hauptsitz Klagenfurt: Feldkirchnerstraße 140, 9020 Klagenfurt Geschäftsführer: Alexander Windbichler Firmenbuch: FN 289918a | Gerichtsstand: Klagenfurt | UID-Nummer: AT U63216601

Oncommand Core(DFM) thresholds for thin provisioning
by Martin 02 Aug '13

02 Aug '13

Does anyone know of Netapp best practise docs or other references on configuring monitoring on aggregates that have thin provisioned volumes: Specifically: Aggregate Overcommitted Threshold (%) Aggregate Nearly Overcommitted Threshold (%) Aggregate Nearly Full Threshold (%) I realise this depends on the rate of change of the data i.e allowing enough time to provision more storage or reduce usage. I am not clear on some of the detail though. Any pointers would be appreciated.

Anyone seen this before? Status is OK now, but if this is a sign its about to fail should I proactively replace this PS?

EXN3000/DS4243 PSU replacement clearance issues
by Ray Van Dolson 29 Jul '13

29 Jul '13

We have EXN3000 (IBM rebranded DS4243's) disk shelves and recently had a PSU go out on one. In attempting to perform the hot swap, we discovered we didn't have enough clearance to pull the PSU out without hitting our vertically mounted CDU's (PDU -- our datacenter team prefers to call them cabinet distribution units). We had to actually lift the CDU off its mount and hold it away from the cabinet to gain the necessary clearance to pull the PSU free. While everything was still running. Definitely precarious! Turns out our racks are 42" deep and I *believe* the recommendation from NetApp is to have 48" racks -- probably exactly for this reason. Can anyone confirm? Other ways to potentially deal with this? I suppose using horizontal CDU's could work as well. Thanks, Ray

How non-disruptive is ifgrp favor <standby interface>
by Fletcher Cocquyt 20 Jul '13

20 Jul '13

Happy Friday We're looking to make a change to the production cluster running 300 VM's including Oracle RAC ahead of the weekend full backups (which are bottlenecking on an edge HP switch - 1000 discards/sec at the peak on this 10Gb port) So we want to run ifgrp favor <standby interface> to balance the traffic out and avoid the discards Do NFS clients (all our VMware datastores are presented via NFS vFilers) notice any issues when the standby interface (e1b) is favored over the active one (e1a)? thanks

FAS2040 to FAS2220 head swap
by James Andrewartha 17 Jul '13

17 Jul '13

Hi all, I have an (empty) single-controller FAS2040 with a DS4243 full of 2TB disks, which is purely used as a SnapVault destination. I need a bit more space in it, and somehow a new FAS2220 with 12 2TB disks is cheaper than 12 2TB disks for the 2040. So this means I need to do a head swap, which I haven't done before. I've had a read of https://library.netapp.com/ecm/ecm_download_file/ECMP1140588 and it seems fairly straightforward, but I thought I'd ask if there's any tips or gotchas I should know of. Also, what are the platform aggregate limits for the 2220? I know the 2040 had a limit of 22 disks (18 data), but can I add the new internal disks to the existing aggregate (which is 2x9+2 at the moment)? Obviously I'll need to do a reallocate after doing this. Thanks, -- James Andrewartha Network & Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph.

AD/LDAP Auth
by Mike B. 16 Jul '13

16 Jul '13

Disclaimer - I'm not Windows savvy so feel free to set me straight if/when/where needed.. I've searched around in the communities site and have read loads of posts about auth'ing admin users against AD. I've also searched the web for hours looking for similar content. I don't feel that all of what I've read fully addressed what I seem to be looking for though. Before I ramble on and on (my apologies in advance), here are some key things that need to be factored in: 1. There is no cDOT - everything is 7G/7-Mode 2. The use of vFilers is **not** an option 3. A 2-way trust **cannot** be established Reading through documentation all the way back to 7.2.5.1 (I didn't go any further), the docs say the following requirements exist to use AD: ======================== A valid CIFS license Your storage system joined to an Active Directory domain A two-way trust relationship established between your storage system’s domain and your LDAP server’s domain, if they are different ======================== >From what I've read, all one needs to do is run through the initial CIFS setup and that should suffice - but the above seems to contradict that. So do you actually /have to have/ a CIFS license AND be "..joined to an Active Directory domain" ?? IIRC you can auth against AD via the LDAP options without making the storage controllers actually be part of any AD. What if they *are* part of an existing AD; can you point them at a different set of AD servers all together for **just** admin auth? That whole trust req above seems to point to no.. Thanks!
