When moving a LUN between different HA pairs in the same SVM to prevent loss of connectivity, the reporting nodes must be modified. The reporting nodes configuration ensures that the initiator paths are properly updated to reflect the new physical location of the LUN. This prevents disruptions in connectivity by maintaining the correct pathing information for the host systems accessing the LUN.

After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.

To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN. This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.

In NetApp ONTAP 9.13.1, one of the automatic features that can be used with iSCSI isLIF failover. This feature ensures that in the event of a network failure or a node issue, the Logical Interface (LIF) will automatically fail over to another available port, maintaining connectivity and minimizing disruption to iSCSI traffic.
