WWN-based Persistent PID assignment

WWN-based PID assignment allows you to configure a PID persistently using a device’s WWN.

When the device logs into the switch, the PID is bound to the device WWN. If the device is moved to

another port in the same switch, or a new blade is hot plugged, the device receives the same PID

(area) at its next login. For information on configuring WWN-based PID assignment, refer to

“Configuring fabric settings” on page 41.

This feature is deactivated by default. When the feature is enabled, bindings are created

dynamically; as new devices log in, they automatically enter the WWN-based PID database. The

bindings exist until you explicitly unbind the mappings through the CLI or change to a different

addressing mode. If there are any existing devices when you enable the feature, you must manually

enter the WWN-based PID assignments through the CLI.

Once WWN-based PID assignment is enabled you must manually enter the WWN-based PID

assignments through the CLI for any existing devices. Any new devices logging in are automatically

entered in the WWN-based PID database. Current WWN-based PID bindings are cleared when you

change to a different addressing mode.

PID assignments are supported for a maximum of 4096 devices; this includes both point-to-point

and NPIV devices. The number of point-to-point devices supported depends directly on the areas

available. For example, 448 are available on an enterprise-class platform and 256 are available on

switches. When the number of entries in the WWN-based PID database reaches the number 4096

or areas are used up, the oldest unused entry is purged from the database to free up the reserved

area for the new FLOGI. Refer to Table 7 for complete information.
