Core Switch PID Format Summary

A Core PID format is one of several addressing formats used in Fibre Channel.
The parameter is used by the routing and zoning services in Fibre Channel fabrics
to identify ports in the network.
The PID format is analogous to specifying the physical switch and port a device is
attached to in data networks. It is not analogous to an IP address. PIDs are
assigned by a Fibre Channel switch when a device logs into the fabric.
A sample PID looks like this: 011F00
Many scenarios cause a device to receive a new PID. For example, it can be
caused by unplugging the device from one port and plugging it into a different
port. (This might occur when cabling around a bad port or when moving
equipment around.) Another example is changing the domain ID of a switch,
which might be necessary when merging fabrics, or changing compatibility mode
settings.
Note:
Switch PID Format enabled, so it is not necessary to change the Core Switch PID format
on these switches. For example, the HP StorageWorks SAN Switch 2/32 and HP
StorageWorks Core Switch 2/64 always use Core Switch PID format 1. This parameter
is always 1 and cannot be changed.

Mixed Fabric Environment with Different Switch Platforms

Fabric OS v2.6.2, v3.1.2, and v4.2.x introduced a new switch PID format:
Extended Edge PID (format 2). Extended Edge PID is useful if you introduce a
Fabric OS 4.2.x switch into a fabric that consists solely of Fabric OS v2.x/3.x
switches. Before adding a Fabric OS 4.2.x switch to such a fabric, refer to the HP
StorageWorks Fabric OS 4.2.x Procedures User Guide for information on the
Extended Edge PID format.
Note:
Extended Edge PID format.

All switches running Fabric OS version 4.0.x or later are shipped with the Core
Switches must operate with Fabric OS v2.6.2, v3.1.2, and v4.2.x to use the
