Verifying the PID mode

About this task

Before connecting the device to the fabric, verify that the WWN-based persistent port identifier (PID) feature on the device matches the other switches in the fabric. This parameter must be identical for all switches in the fabric and is set using the configure command.

Procedure

Log into the device using one of the following methods:
- A serial console connection to the active CP blade. The active CP is indicated by an illuminated blue LED on the blade front panel.
- A Telnet session using the chassis management IP address.
Log into the device using admin as your password. If you have not changed the default password, use password.
Check the PID setting using the configshow command as in the following example. You can use the| grep -i pid qualifier to pinpoint the PID information.
```
switch:admin> configshow | grep -i pid
fabric.ops.mode.pidFormat:1
fabric.wwnPidMode:1
```
The 1 indicates that the WWN-based persistent PID feature is enabled. The default value is 0 for disabled.
Set the PID mode if necessary using the configure command.
Refer to the "Fabric Parameters" section under the "Configure" command in the Fabric OS Command Reference for details on configuring WWN Based persistent PID.
