Example of system configuration
(connected to storage via FC switch)
An example of connection to storage via FCSW with 4-Gbps Fibre-channel adapter is as
follows:
This example is described in terms of storage.
Four partitions (LPARs) are configured in LPAR manager, each of which is allocated a
system path and data path. They are implemented redundancy with redundancy software
such as HiCommand Dynamic Link Manager (HDLM) and Hitachi Fibre Channel – Path
Control Manager (HFC-PCM).

The four ports share each HBA port using the FC sharing function.

Make sure to connect the storage via FCSW to use the FC sharing function with 4
Gbps fiber channel adapter. Enable the N-Port ID Virtualization (NPIV)function of
FCSW for using the NPIV function of FCSW.

Multiple LPARs can share a single HBA port. To share a port, allocate the port to
LPARs on the LPAR manager screen using the WWN identifier (vfcID). The
following is an example for allocation with vfcID (1 to 8) in this configuration.
vfc ID
HBAO HBA1
Port 0 Port 1 Port 0 Port 1
1 LPAR1 allocated LPAR1 allocated LPAR1 allocated LPAR1 allocated
2 LPAR2 allocated LPAR2 allocated LPAR2 allocated LPAR2 allocated
3 LPAR3 allocated LPAR3 allocated LPAR3 allocated LPAR3 allocated
4 LPAR4 allocated LPAR4 allocated LPAR4 allocated LPAR4 allocated
