26 Overview of LUN Manager

• Point-to-point: The simplest fibre topology directly connects two devices together.

Figure 7 FC-AL and Point-to-point topologies

When configuring the system, use the LUN Manager pane to specify whether the hosts and array are

connected by a fabric switch.

If you use a fabric switch, you must specify FC-AL or point-to-point in the LUN Manager pane (by default,

FC-AL is specified). If you use a fabric switch, see the fabric switch’s documentation to learn whether you

should use FC-AL or point-to-point. Some fabric switches require that you specify point-to-point to get the

system running.

If you are not using a fabric switch, you must specify FC-AL. For more information, see ”Specifying Fibre

Channel topologies” on page 99.

Fibre Channel port addresses

When configuring the system, you must set addresses for Fibre Channel ports. When addressing Fibre

Channel ports, you can use the AL-PA (arbitrated-loop physical address) or loop ID as the address (see

Table 2).

For more information, see ”Addressing Fibre Channel ports” on page 99.
