NS0-162 Exam Dumps : NetApp Certified Data Administrator (ONTAP)

When you perform an upgrade using ONTAP System Manager 9.8, you can use the automated nondisruptive update (ANDU) feature, which simplifies and streamlines the update process. The latest available images will appear in the ONTAP System Manager interface, and you can select the image you want to install. The update history is available within the ONTAP System Manager interface, and you can view the status and progress of the update. You do not need to manually upload the images to the cluster or download them from the NetApp Support site, as ONTAP System Manager will automatically download and upload the images as needed. References :- Automated nondisruptive ONTAP upgrade, How to Upgrade to ONTAP 9.8

 Temperature Sensitive Storage Efficiency (TSSE) is a method of compressing data based on data “temperature”, or how often the data is used. “Cold” data, or data that is not used often, is recompressed with a higher compression ratio for increased storage efficiency. TSSE is enabled automatically on newly created thinly provisioned AFF volumes, not thick provisioned volumes. TSSE operations on AFF arrays are automatically throttled depending on whether data is hot or cold, to balance performance and efficiency. TSSE is not supported on Cloud Volumes ONTAP or ONTAP Select, as these platforms have different storage characteristics and requirements. References :- Temperature-sensitive storage efficiency overview, How does Temperature Sensitive Storage Efficiency affect SnapMirror?, ONTAP Temperature Sensitive Storage Efficiency (TSSE) – A Simple Introduction

 The problem is that the NFS export policy only allows access to the IP range of 192.168.10.11-12, which does not include HOST 3’s IP address of 192.168.10.13. Therefore, the ESXi host cannot mount the NFS datastore. To solve the problem, you need to add HOST 3’s IP address to the NFS export policy, or modify the IP range to include it. This will grant the ESXi host the permission to access the NFS datastore. References :- ONTAP 9 Network Management Guide, ONTAP 9 NFS Reference, Troubleshooting NFS datastore connectivity issues (1003967)
