Hi Team, I have two environment(Prod,DR) and I have deployed app on Prod. I am planning to perform the failover from prod to DR with the help of trident. I have installed and configured the backend on both cluster and followed the below URL in order to implement the DR failover. I have stopped the SVN on prod and try create the backend in DR and discover the volume as per the steps described in below URL but unable to find the disk. Can you please help me to find the right approach in order to do that? https://netapp-trident.readthedocs.io/en/stable-v19.04/dag/kubernetes/backup_disaster_recovery.html Regards, Bala

Hey I have recently discovered this newly Microsoft released vulnerability on SMB clients. I wanted to know - If the SMB vserver is affected by this vulnerability on clustered data ontap - If I have to disable SMB compression on the NetApp Vserver? Is this feature exists? - If My windows SMB clients working with the netapp controller need to disable smb-compression? Thanks Tankwell

Somebody has experience using Trident version 20.10.1 and the K0s Kubernetes runtime (running k8s 1.22.5). I used the operator to install. When verifying the installation, I'm able to create backend and do some persistent storage claim, the volume is correctly created. But when using this inside pod I have issue, when describing the pod I see " CSINode does not contain driver csi.trident.netapp.io.

Seeing a strange issue with Citrix and using NetApp storage. The current Citrix environment is out of support and uses HPE Nimble LUNS presented via iSCSI. VMs seem to work fine on these, new VMs can be made, a new LUN can be created, presented and VMs created which all work ok. I have a FAS2552 running ONTAP 9.8P7 with a LUN presented to the same Citrix environment and VMs fail to boot. The NetApp LUN is presented to Citrix successfully and a Storage resource created from it. Multipathing is established on all hosts and the VM base image can be copied across successfully. When booting the VM from a clone of the base identity disk it boots to the Windows Logo (Windows 10) before failing and rebooting. This happens a number of times before going to the recovery prompts. Has anyone seen this behaviour before/managed to resolve? I've exhausted everything I can think of. Versions below Windows OS version - 2019 LTSC Citrix Virtual App & Desktop version - 1909 VDA version - 1909.1.0.23058 Citrix App Layering Appliance version - 20.9.0.3 NetApp Model - FAS 2552 ONTAP - 9.8P7 VM OS - Windows 10.

Help Please/ Im currently working as a systems administrator, and they use Netapp for their storage of data. I would like to be able to develop my skills on the storage and understand that there is a simulator available. I've attempted to register under my company details but Im missings some details and therefore cant proceed any futher. I would like to use the simulator at home as I can build a test enviroment with a couple of vm's if required. If someone has a copy available or knows of a link Ican obtain one I would be most grateful.
