3 Basic port configuration

Persistent binding

Persistent binding enables you to permanently assign a system SCSI target ID to a specific FC device. Persistent binding can be achieved by binding to world wide port name (WWPN), world wide node name (WWNN), or device ID (DID).

You can access the Persistent Binding dialog box by selecting the Host or an HBA from the device tree.

Enabling and disabling persistent binding using HCM

Persistent binding can be enabled or disabled from the HCM GUI using the following steps:

1.Launch the Basic Port Configuration dialog box at the port level.

2.Check or uncheck the Persistent Binding check box in the Basic Port Configuration dialog box.

Enabling and disabling persistent binding using the BCU

Target persistent binding enables target port world wide name binding to a persistent target ID for the OS stack. Using the -list operand, you can query the list of mappings from the persistent binding module.

Enter the following commands to configure target persistent binding:

•bcu pbind --list<port_id> [<pwwn>]

•bcu pbind --clear<port_id>

Refer to “pbind” on page 150 for details about this command.
