There are scenarios where it might be useful to know the node, port, or lif to which a specific client is connected. If a specific client has connectivity issues, it is necessary to determine the node on which you can run a packet trace. If a specific client is running an exceptional load, it might help to determine the lif to which it is connected for load balancing purposes.

In all versions prior to clustered Data ONTAP 8.2.1, 64-bit aggregate conversion is triggered by adding a single disk to an aggregate that is 16 TB; in 7MODE prior to 8.1.4P4, you must have enough disks to exceed 16 TB before you can upgrade the aggregate to 64 Bit.
