HP StorageWorks Fabric OS 6.x administrator guide (5697-7344, March 2008)

252 Using the FC-FC routing service
Connectivity modes
You can connect to M-EOS fabrics in both McDATA Open mode or McDATA Fabric mode. If the mode is
not configured correctly, the port is disabled because of incompatibility.
To allow interconnectivity with M-EOS SANs, the command line interface (CLI) command portCfgExPort
uses the -m option to indicate the connectivity mode. Table 60 lists the valid parameters to use with the -m
option to set the connectivity mode.
You can display the current operational mode of the EX_Port by issuing the portCfgExPort command
with the port number as the only parameter.
See ”Configuring an interfabric link” on page 225 for details about the portCfgExPort command,
which is used for McDATA Fabric mode on Fabric OS v5.2.0 or later.
Configuring the FC router
When configuring an HP fabric to connect to a Native McDATA fabric, you must perform some preparation
on the FC router. The following procedure shows how to connect an EX_Port of an FC router fabric to a
Native McDATA fabric configured in Fabric mode.
1. Verify the Native McDATA firmware version. To display the front domain on the M-EOS fabric, use the
M-EOS show command.
2. Using the version command, make sure that Fabric OS 6.0 is installed on the 400 MP Router or
4/256 SAN Director or DC Director with an FR4-18i blade, as shown in the following example:
