FDMI reporting with qla2xxx driver on Linux
by Momonth 09 Dec '16

09 Dec '16

Hi, I recently noticed that qla2xxx (Qlogic HBAs) driver on Linux is capable of reporting FDMI. By default it sends "Linux-default", and I'm failing to see how to change it to actual host name as it becomes way more handy then =) Any ideas? Cheers, Vladimir

Moving shelves with root aggr and root vol (7-mode) from one Filer to another
by Martin 22 Mar '16

22 Mar '16

Hi, I have one 7-mode Filer that I will be decommissioning which has data on it I need to migrate to another 7-mode Filer. We don't have space to mirror the data to the new Filer, want to reuse the shelves on the new Filer and this is a quicker cut over. The four DS4243 shelves have a single aggregate (aggr0) with various volumes on it (exported via NFS) including the root volume for the controller (vol0). I found the KB on moving shelves and aggregates between controllers but it doesn't mention what to do about a Filer that has vol0 and root aggr on the shelves. My plan is: 1. Disable disk auto assign on both source and destination Filer on both controllers options disk.auto_assign off 1. Reboot the source controller into maintenance mode 2. Offline aggr0 aggr offline aggr0 3. Uknown the disks on the shelves on the source controller disk assign disk_name -s unowned -f 4. Shutdown the Source Filer and power off along with shelves 4. Power down the destination Filer and add SAS card to new Filer (not enough SAS ports for new loop) 5. Physically moves shelves from source Filer to destination Filer 6. Cable shelves and change shelf IDs along with a powercycle to ensure shelf IDs don't conflict 7. Assign the disks on the new Filer disk assign disk_name 8. As the aggregate is aggr0 and new Filer also has aggr0 it gets renamed to aggr0(1) and foreign 9. Check the status of the new aggregate aggr status aggr_name 10. Rename the new aggregate from aggr0(1) to aggr1 aggr rename aggr0(1) aggr1 11. Online the aggregate on the destination Filer as it is longer labelled as foreign aggregate. aggr online aggr1 12. Check the aggregate status on the destination Filer aggr status aggr1 13. Export the volumes on the destination Filer via /etc/exports and exportfs -r -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Moving-shelves-with-r… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

NetApp API authentication
by Edward Rolison 01 Mar '16

01 Mar '16

Having started to review some of our filer automation scripts, I'm starting to look in a bit more detail at the API. My first conclusion is - the perl SDK doesn't actually seem to do anything much - it seems to be a reimplementation of LWP and and XML Parser. Given I have LWP and XML::Twig installed, and am making API calls just fine, is there anything I'm missing here? Aside from that though - authentication types. I currently use ssh public-private key pairs, in a trusted account on a management station to enable 'doing stuff' with filers. It _looks_ like my only option with the API is to create a designated service account, and assign permissions... and then embed a username and password in a script somewhere. That just doesn't sit well with me - I like what ssh-agent will do in 'unlocking' key files, and I don't like embedding (potentially privileged) usernames and passwords ... anywhere. Does anyone have a better solution than a couple of designated API users (privileged and read only) with a file somewhere embedding their username and password? Does anyone have a better approach?

storacl / local ontap only users
by Philbert Rupkins 27 Feb '16

27 Feb '16

Toasters, I have a client who needs to use SnapDrive for Windows. I'd like to use storacl to limit SnapDrive visibility to that client's volumes and fibre channel luns. I'd also like to avoid joining the filer to the AD domain. I created a local ontap account that is a member of the local administrators ontap group. I can configure SnapDrive's transport protocol settings to connect to the filer using the ontap account via https. SnapDrive see's all of the volumes on that filer as expected. Is it possible to create storacl rules that apply to SnapDrive for Windows when connecting via https using a local ONTAP user to a filer that is not a member of domain? Everything I see in the storacl documentation seems to only apply to filers that are a member of a domain. Much appreciated, Phil

Hi all, I have a 3170 FAS, with 25 shelves of 1TB disk , 14 per shelf. I use the command storage show disk, and see al 350 disks, yet if I use the command disk show, I see one 242. Can anyone suggest what may be causing the difference in output? Thanks, Mark Sent from my iPhone

Live alerting for crypto files
by Basil 21 Feb '16

21 Feb '16

Is there a way to use fpolicy as an alerting system for ransomware infections? Everything I've read about native policies seems to indicate that it's only for blocking files by extension, but is there a way to have it generate a notification of some sort when it blocks something?

NwkThd_00:warning: NFS response to client was slow
by Edward Rolison 16 Feb '16

16 Feb '16

NwkThd_00:warning]: NFS response to client xx.xx.xx.xx for volume 0x1234567 was slow, op was v3 write, 65 > 60 (in seconds) I have a filer head, on which I'm hosting ESX datastores. I've had a couple of instances now of this error (or one rather similar). It correlates with VMware getting upset and VMs going read only. But it doesn't actually give me any insight into what is going on. Has anyone run into this, and can give some further insight as to what might be causing and where I can look?

Showmount (cdot 8.3.1) shows multiple "/" because of root mir
by Fred Grieco 11 Feb '16

11 Feb '16

Toasters, It's great to see showmount back in ontap 8.3. I'm having an issue with it though. It shows multiple root entries ("/") presumably because of the ls mirrors for the vs root. Is there a way to disable this display? Is this a bug? Mounting works fine. But we have a lot of systems that use automount, and a lot of processes that parse the showmount output, so I'm told. Thanks, Fred

where does CDOT keep the .7z files for the configuration backups?
by Rue, Randy 10 Feb '16

10 Feb '16

Hello All, I see how/where I would set up the uploading of the backup files to an outside destination but only via FTP or to a writeable (put-ready) http destination. Where do those files actually sit on the cluster? Anywhere that I can reach via NFS or CIFS or any other way, like through the SPI web interface? Hope to hear from you, Randy

Hide snapshots from NFS clients in 8.3.1
by Jeremy Webber 09 Feb '16

09 Feb '16

In 7-mode we are able to make snapshots accessible, but invisible to NFSv3 clients. In this mode there is a .snapshot directory, but if you ‘ls’ that directory it appears empty. However, if you ls .snapshot/hourly.0 say then you can see that the snapshot is in fact there. We now have an 8.3.1 CDOT filer and have not been able to work out how to reproduce the behaviour. The snapshots are either accessible and visible (which causes problems for programs which walk the tree) or not accessible at all. NetApp support have not been able to help so far. Can anybody on this list? Thanks, Jeremy p.s. the relevant 7-mode option is: nfs.hide_snapshot on -- Jeremy Webber Senior Systems Engineer Animal Logic Pty Ltd Tel: +61 2 8310 3577 Main: +61 2 9383 4800 Fax: +61 2 9383 4801

Add vfiler0 to a Domain
by Philbert Rupkins 05 Feb '16

05 Feb '16

Toasters, I have a 7-mode system that hosts a number of non-default-vfilers. Several non-default-vfilers have been added to an Active Directory domain. vfiler0, however, is not a member of the domain on either controller. I have a new Fiber Channel client that is going to utilize this 7-mode system. This client plans to use a SnapManager product that would benefit from vfiler0 being added to the domain. Will adding vfiler0 to the domain (cifs setup) affect the configuration of any of the existing vfilers? Thanks, -Phil
