Gathering Configuration Information for FC Port Parameters

Once Pathlight VX is attached to the host, the FC port settings are automatically detected. At install, log into

Service > Port Configuration > Configure and update Table 22

to record the settings used to define the

FC port parameters of the Pathlight VX. You can configure FC ports 1, 3, and 6 on each blade. FC port 6 is

reserved for connections to physical libraries, and therefore some of the options available to ports 1 and 3

are not available to port 6. See "Configuring FC Port Parameters" in the Pathlight VX Installation Guide.

For the Connection Options parameter, valid values are: Loop, Point-to-Point, or Loop Preferred.

General guidelines to determine the Connection Option setting include:

• If you connect direct to a HBA (NL_Port), use Loop.

• If you connect to a switch (N_Port), use Point to Point.

• If you connect to either a host or switch, you can use Loop Preferred. However, note that this

setting requires negotiation between the two connection points, which can result in varying Port

Mode settings.

Additional configuration information for the Connection Option setting includes:

• If you specify Point-to-Point, you should be able to use the default values provided on either

the Pathlight VX Service Interface or the Pathlight VX User Interface.

• If port 6 on one or both FC blades is cabled to an external aggregation switch, port 6 should be set

up in Point-to-Point mode.

• If the specific network environment causes you to specify either Loop or Loop Preferred,

determine the following values based on the customer environment.

• Blade ID values are FCB1 or FCB2.

• FC port values are 1, 3, or 6.

• For the Loop ID parameter, valid values are: any number between 0 and 125.

• For the Speed parameter, valid values are: Auto, 1 GB/sec, or 2 GB/sec.

• For the Frame Size parameter, valid values are: 512, 1024, or 2048.

• For the Port Mode parameter, valid values are: Target or Target & Initiator. Target

mode is not available for port 6.

After the Pathlight VX is installed, you can specify most of this information in the Pathlight VX Service

Interface. The field names on the Pathlight VX Service Interface are identical to the headings in Table 22
