NS0-521 Implementation Engineer - SAN ONTAP Exam

When using Fibre Channel Protocol (FCP), the minimum number of FC switches needed to redundantly attach three ESXi hosts is 2. This setup ensures that each host has multiple paths to the storage, providing high availability and fault tolerance. Each ESXi host should be connected to both switches, allowing for continuous operation even if one switch fails.

To move SAN LIFs to new nodes that are members of a portset during maintenance of a NetApp AFF ONTAP cluster, you should take the following steps:

Remove the LIF from the portset : This ensures that the LIF is no longer associated with the current node, preparing it for the move to the new node.

Take the SAN LIF offline : This step is necessary to make configuration changes without causing disruption to the SAN hosts. Once offline, the LIF can be moved to the new node and reconfigured as needed.

These actions help maintain the integrity and performance of the SAN environment during the migration of LIFs.
