Considerations for LIFs in cluster SAN environments
You must be aware of certain LIF considerations in a SAN environment.
Initiators must use Multipath I/O (MPIO) and asymmetric logical unit access(ALUA) for failover capability for clusters in a SAN iSCSI or FC environment because SAN does not support automatic failover for LIFs.
At least one SAN LIF of the appropriate protocol must be configured on each node that hosts a mapped LUN and the node’s HA partner.
You can configure two LIFs per node, one for each fabric being used with FC and to separate Ethernet networks for iSCSI.
Some options are not applicable for iSCSI or FC.
For example, you cannot use IP addresses with FC.
