Figure 85 shows iSCSI and Fibre Channel hosts in a multiple-port configuration.
Figure 86 on page 121 shows an incorrect configuration of a single host with both
iSCSI and Fibre Channel connections.
Important: Do not cable the storage subsystem and host systems as shown in
Figure 86 on page 121. A storage subsystem with the incorrect storage
topology might appear to be functional, but incorrect cabling can
potentially have unpredictable results.
