Managing LIFs for all SAN protocols

LIFs can be removed from port sets, moved to different nodes within a storage virtual machine (SVM), and deleted.

  • Configuring an NVMe LIF
    Certain requirements must be met when configuring NVMe LIFs.
  • Considerations for SAN LIF movement
    You only need to perform a LIF movement if you are changing the contents of your cluster, for example, adding nodes to the cluster or deleting nodes from the cluster. If you perform a LIF movement, you do not have to re-zone your FC fabric or create new iSCSI sessions between the attached hosts of your cluster and the new target interface.
  • Removing a SAN LIF from a port set
    If the LIF you want to delete or move is in a port set, you must remove the LIF from the port set before you can delete or move the LIF.
  • Moving SAN LIFs
    If a node needs to be taken offline, you can move a SAN LIF to preserve its configuration information, such as its WWPN, and avoid rezoning the switch fabric. Because a SAN LIF must be taken offline before it is moved, host traffic must rely on host multipathing software to provide nondisruptive access to the LUN. You can move SAN LIFs to any node in a cluster, but you cannot move the SAN LIFs between storage virtual machines (SVMs).
  • Deleting a LIF in a SAN environment
    Before you delete a LIF, you should ensure that the host connected to the LIF can access the LUNs through another path.
  • Considerations for adding nodes to a cluster
    You need to be aware of certain considerations when adding nodes to a cluster.
  • Configuring iSCSI LIFs to return FQDN to host iSCSI SendTargets Discovery Operation
    Beginning in ONTAP 9, iSCSI LIFs can be configured to return a Fully Qualified Domain Name (FQDN) when a host OS sends an iSCSI SendTargets Discovery Operation. Returning a FQDN is useful when there is a Network Address Translation (NAT) device between the host OS and the storage service.
