Automated vs Manual NDU
by Philbert Rupkins 15 Jul '20

15 Jul '20

Toasters, What's your preference for non-disruptively upgrading a switch based ONTAP 9 cluster - automated NDU or manual (rolling) NDU? Happy to hear of both positive and negative experiences, if any. The cluster in question consists of 3 HA pairs so the automated upgrade will default to rolling. The general recommendation is to use the automated procedure but there are concerns about lack of control, especially in the event of issues. Each HA pair in the cluster hosts critical prod workloads. No access to a test cluster so there isn't much opportunity to build confidence in the automated procedure ahead of time. I am aware of the ability to pause the automated upgrade. Leaning toward manual at the moment due to lack of exposure to the automated process. Cheers, Phil

DFS-R is not supported. ONTAP can be a DFS-R target, but not in a DFS-R setup. For SMB access across sites in ONTAP, your options are: - Third party software, such as Peer - If this is in the cloud, you can use Talon Software (as covered in this podcast: https://soundcloud.com/techontap_podcast/episode-233-netapp-acquires-talon-…) - if you can hold off for a bit, a future release will support SMB FlexCache. Check with your SE for an NDA update on that. -----Original Message----- From: Toasters <toasters-bounces(a)teaparty.net> On Behalf Of Scott Eno via Toasters Sent: Friday, July 10, 2020 2:26 PM To: Toasters <toasters(a)teaparty.net> Subject: NetApp Security WARNING: This is an external email.

DFS-R
by Scott Eno 10 Jul '20

10 Jul '20

Hi, According to the latest docs for ONTAP, “Logging of NT File System (NTFS) events in the change journal” is not supported with CIFS. Does this prevent netapp shares from being used as target folders for DFS replication?

hardware or software based disk ownership?
by Rue, Randy 09 Jul '20

09 Jul '20

Hello all, I sure do have a lot of questions lately, I'm hoping to consolidate two aggregates into one for better space use, knowing that we might lose some performance. We're currently running two SVMs, each with its own aggregate, one one each node of a FAS8020 cluster running 9.1P6 (I know, I know). I inherited ownership of this cluster and didn't set it up. When I try to add a new volume to one SVM I can only see one aggregate but I'd like to put that volume on the other aggr. How can I tell if I'm running HW or SW based ownership? To confirm, if I was running SW based should I be able to use either aggr on either SVM? And last, is there any way to change from HW to SW without tearing it all up? Randy

any reason not to rename an aggregate?
by Rue, Randy 09 Jul '20

09 Jul '20

We're changing our layouts and it would make functional sense to have a consistent naming scheme include an existing aggregate. Is there any impact from renaming an aggregate other than a new display name? Randy

Also watch out for the constituent member ( volumes under the covers ) count - I find the "default" is too high sometimes for the solution I am looking for.

fstab nfsv3 mount favorites?
by Scott Eno 07 Jul '20

07 Jul '20

Hi, It’s been a number of years since I worked in a Linux/NFS shop, so while I search for my old fstab mount options for a one-off project, does anyone have their go-to fstab nfsv3 mount options handy? The exported volume is on an ONTAP 9.6 cluster if it matters.

ONTAP Simulator
by Philbert Rupkins 06 Jul '20

06 Jul '20

Hello Toasters, Does NetApp provide the option to download old versions of the ONTAP Simulator? I'm looking for version 9.3 (any patch release) specifically but I am coming up empty. The oldest version of the simulator I see available is 9.5P6. I'm finding no links to older versions of the simulator anywhere on the support site. Cheers, Phil

Change Serial Number
by netapp_newbie 03 Jul '20

03 Jul '20

Hello, I bought old netapp but I have no license. I asked the guy who I bought he said this controller replaced in past but it should be licenses. I checked lots of doc , if controller replaced license should be generated by netapp but ı guess they forget to the that and now controller has no support and eoa. As a result ı have controller with no license. I have the old license keys but it locked with the old controller serial number. Is there anyway to change serial number. Because if ı can change serial number with old ones ı can use old license key. Thanks, -- Sent from: http://network-appliance-toasters.10978.n7.nabble.com/
