Example Of An Incorrect Configuration: Single-Host, Iscsi And Fibre Channel - IBM System Storage DS5020 Installation, User's, And Maintenance Manual

Figure 64 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 64. A storage subsystem with the incorrect storage topology
might appear to be functional, but incorrect cabling can potentially have
unpredictable results.
