I have Netapp FAS8300 with 3 DS224C with 60 disk, I added 2 additional DS224C with 48 disk. Current Configuration : 2 Node Netapp FAS8300 Ontap 9.9.1 3 DS224C disk shelf ( Total 60 disk each disk 1.8 TB) shelf is (01,02,03) Addition : 2 DS224C disk shelf ( Total 48 disk each disk 1.2 TB) All cable connectivity showing green, disk self show in Ontap GUI and CLI with new shelf id (04 &05). Issue: Not able to create new aggregrate. New added disk shelf Disk show broken/fail in ontap gui and cli. (disk not assign to any node) Try to unfail disk command , error received “ disk unfail fail reason : “ disk not exist”. We have checked all disk shelf cable and connectivity using cli, all disk shelf cable and connectivity show connected.

Hi,
What is correct info regarding Automatic node referrals during a Hyper-V setup over SMB? I have found a document from netapp, published 09/09/2018: https://kb.netapp.com/app/answers/answer_view/a_id/1030128/~/how-to-set-up-svm%2Fcifs-for-hyper-v-over-smb-
Under chapter: General SVM/CIFS Server and Share Configuration Requirements, chpater 12.3
it says Automatic node referrals must be disabled for Data ONTAP versions 8.2.0 and earlier. Automatic node referrals are supported in Data ONTAP 8.2.1 and later.
I just wonder if that is correct.. that is the only information that says it is OK to use on CIFS -share to Hyper-V (If you have above 8.2.0)
All other artical says that it is not supported. (Example "SMB/CIFS Config guide for Hyper-V/SQL, from Netapp, published feb 2019" https://library.netapp.com/ecm/ecm_get_file/ECMLP2494083 on Page 20: • Automatic node referrals must be disabled) My problem today is that one of my nodes in my HA cluster (ontap 9.4) owns all SMB-sessions. I do not know why the SVM-server forward all SMB traffic to one of the node. I have two SMB LIF´s, one to each node in the cluster. The DNS (external) is setup an both LIF´s have its own IP address registered in the DNS. When ping from my hyper-V hosts the DNS roundrobin works fine. But it does not matter, when the SVM-server keeps sending all traffic to the same node. If I do a simple filecopy from my hyper-v server to the CIFS-share by using IP-address, then the traffic goes to the correct node. That is why I want to use Automatic node referrals, to split the load equal over my nodes in the cluster.
Any tips? Best regards, Pelle Dahlkild

Hello, we have a vSphere 8 Cluster and an AFF8040 connected via NFS to each Host. My question is, what is the best virtual SCSI Controller for the Windows vm's. At this time we use the paravirtual Controller, but somewhere I read that the virtual NVMe Controller would be better. Is there a best practise for this? Thanks.

Hi Gurus, What should be the ONTAP CLI required to find all the snap reserve which is used more than 50%? please advise. Not just from df -h o/p, I need to have a query to specify the thresholds like >50% etc. as I have 200+ vols on the cluster (CDOT). Regards, BM

Hi All, I haven't explored yet repurposing an existing shelve (DS4246) from FAS2552 and placing it to a newly purchased FAS2720. I am trying to check some documentation on how to do that but having a hard time finding one. Seeking your assistance on how we can proceed migrating the data from the old FAS2552 with DS4246 and moving it to FAS2720. Thank you.
