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 configurations: You must use different data LIFs for 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.
