Specifying preferred path example
Figure 70 shows a portion of a more complex 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. Select Configure > Preferred Path in Switch 1’s Element Manager window to configure the path
on Switch 1. The Add Preferred Path dialog box appears.
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 71 on page 154), 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. Select Configure > Preferred Path in Switch 2’s Element Manager window to configure the path
on Switch 2. The Add Preferred Path dialog box appears.
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.
