Setting FC switch

FC switch ports, which will be connected to 4 Gbps Fibre-channel adapters in
shared mode, should have NPIV enabled.
With the “portcfgshow” command, you can determine whether or not NPIV is
enabled.
If NPIV is disabled, enable the NPIV using the “portcfgnpivport” command of the
FC switch.
See the manual attached to the FC switch for how to set and confirm NPIV.

When the transfer rate of the FC port in an FC switch is the default value,
auto-negotiation, the logical unit (LU) in storage might not be viewed because of
the discrepancy between the transfer rate of the FC port and that of the
Fibre-channel card.
In this case, change the transfer rate of the FC port to the same rate of your
Fibre-channel card using the “portcfgspee” command.
