Failover Reference Configuration 7:
One host with two Fibre Channel HBAs, one Fibre Channel switch and one Dell PowerVault^"*
with a Single Fibre Channel drive
In this configuration, failover occurs only if one of the HBAs fails. This configuration only supports data
path failover as there is no second drive to failover the control path. The physical connection of this
configuration is shown in Figure 7.
