PIDs and PID binding overview

If the NPIV device has Dynamic Persistent PID set, then the same ALPA value in the PID is used.

This guarantees NPIV devices get the same PID across reboots and ALPAs assigned for the device

do not depend on the order in which the devices come up.

Enabling automatic PID assignment

NOTE

To activate the WWN-based PID assignment, you do not need to disable the switch.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the configure command.

3. At the Fabric Parameters prompt, type y

4. At the WWN Based persistent PID prompt, type y

5. Press enter to bypass the remaining prompts without changing them.

Example of activating PID assignments.

Configure...

Fabric parameters (yes, y, no, n): [no] y

WWN Based persistent PID (yes, y, no, n): [no] y

System services (yes, y, no, n): [no]

Assigning a static PID

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the wwnAddress -bind command to assign a 16-bit PID to a given WWN.

Clearing PID binding

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the wwnAddress -unbind command to clear the PID binding for the specified WWN.

Showing PID assignments

1. Connect to the switch and log in using an account assigned to the admin role.

2. Based on what you want to display, enter the appropriate command:

• wwnAddress –show displays the assigned WWN-PID bindings.

• wwnAddress –findPID wwn displays the PID assigned to the device WWN specified.
