The auto-revert option determines whether a LIF automatically reverts to its home port after a failover event. If this option is set to true, the LIF will revert to its home port when it becomes available. If this option is set to false, the LIF will remain on the failover port until manually reverted. In this scenario, the cluster LIFs are not on their home ports after an ONTAP upgrade, which might have triggered a failover event. Therefore, setting the auto-revert option to true would change this outcome and ensure that the LIFs return to their home ports after the upgrade. References :- network interface modify, Verify all LIFS are on home ports after ONTAP upgrade

The igroup is a logical grouping of initiators that can access a set of LUNs. The igroup must contain the IQNs (iSCSI Qualified Names) or WWPNs (World Wide Port Names) of the initiators that need to access the LUNs. In this scenario, the igroup named “ESX” has the iSCSI protocol and the VMware OS type, but it does not have any initiators listed. This means that the VMware hosts cannot authenticate and connect to the LUNs in the SVM. To resolve this issue, the igroup must be populated with the correct initiators that match the VMware hosts. This can be done by using the igroup add command or the System Manager GUI12. References :- Create an igroup, Add initiators to an igroup

 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)
