Requirements for LIF creation in a MetroCluster configuration

You should be aware of the requirements for creating LIFs when configuring your network in a MetroCluster configuration.

You must consider the following guidelines when creating LIFs:

Fibre Channel: You must use stretched VSAN or stretched fabrics
IP/iSCSI: You must use layer 2 stretched network
ARP broadcasts: You must enable ARP broadcasts between the two clusters
Duplicate LIFs: You must not create multiple LIFs with the same IP address (duplicate LIFs) in an IPspace
NFS and SAN configurations: You must use different storage virtual machines (SVMs) for both the unmirrored and mirrored aggregates

Verify LIF creation

You can confirm the successful creation of a LIF in a MetroCluster configuration by running the metrocluster check lif show command. If you encounter any issues while creating the LIF, you can use the metrocluster check lif repair-placement command to fix the issues.
