, each iSCSI host discovers one iSCSI target for every physical Fibre Channel target.
When the Gigabit Ethernet interface of the VRRP master fails, the iSCSI session is terminated. The host
then reconnects to the target and the session comes up because the second Gigabit Ethernet interface has
taken over the virtual IP address as the new master.
Tip
Ports that act as VRRP master and backup can be on different switches. If you have a static WWN
configuration for iSCSI initiators, configure a different WWN for the iSCSI initiator for each switch. If
you use a proxy-initiator, be sure to configure a different pWWN on each iSCSI interface for each VRRP
port used.
Ethernet PortChannel-Based High Availability
All iSCSI data traffic for one iSCSI link is carried on one TCP connection. Consequently, the aggregated
bandwidth will be one Gbps for that iSCSI link.
