Connecting to Fabric Switch (NF9320-xSxx/SS11x, NF9330-xSxx, N8406-019/020 or
other)
Connect the connections from a server and a disk array unit to the same port
number of each switch by Fabric Switch or by zoning group, as shown in the figure
below.
Target IDs starting from 0 are assigned to Targets recognized by the server in order from the
lower numbered N_Port ID (lower numbered Port of Switch).

[Note] If you mix up the RAID Storage connected to Ports of Switch0 and Switch1, cluster setup is not possible
since Target IDs differ between controller 0 and controller 1.
