Specifying Preferred Path Example
Figure 29 on page 113 displays a portion of a more complex SAN. This section
provides a description of the activities related to specifying a Preferred Path for
that SAN. In this example, we will do the following:
■ Specify a path between the Source Device and Destination Device A, going
through Switch1, Switch 2, and Switch 3 (the desired data flow is shown as
Data Flow 1).
■ Enter data through port 14.
■ Exit data through port 45.
■ Make Switch 3 the destination device.
Use the following procedure to accomplish the above tasks.
1. Click Configure > Preferred Path in Switch 1’s Element Manager window
to configure the path on Switch 1. The Add Preferred Path dialog box
displays.
2. Click 14 in the Source Port field.
3. Click 45 in the Exit Port field.
4. Click 3 (Switch 3’s domain ID) in the Destination Domain ID field.
This procedure only specifies that data will enter and exit Switch 1 through
specific ports on its way to Switch 3. This process does not specify a Preferred
Path for data moving through Switch 2. To specify paths through Switch 2
(
Figure 30 on page 114), we will do the following:
■ Enter data through port 11.
■ Exit data through port 21.
■ Make Switch 3 the destination device.
Use the following procedure to accomplish the above tasks:
1. Click Configure > Preferred Path in Switch 2’s Element Manager window
to configure the path on Switch 2. The Add Preferred Path dialog box
displays.
2. Click11 in the Source Port field.
3. Click 21 in the Exit Port field.
4. Enter 3 (Switch 3’s domain ID) in the Destination Domain ID field.
