Updating Switches to the Core PID Addressing

147Fabric OS Procedures Version 3.1.x/4.1.x User Guide

■ Detailed Update Procedures for HP/UX and AIX provides examples of

step-by-step instructions for certain PID-bound devices. These procedures are

applicable to any of a broad class of routine maintenance tasks; indeed, they

would apply to these devices in many scenarios with any Fibre Channel

switch in any addressing mode.

Note: It is recommended not to use drivers that bind by PID. There are several routine

maintenance procedures which may result in a device receiving a new PID.

Examples include, but are not limited to:

■ Changing “Compatibility Mode” settings

■ Changing switch Domain IDs

■ Merging fabrics

■ Relocating devices to new ports or new switches (that is, for Add, Move, and

Change type operations)

■ Updating the core PID format

■ Using hot spare switch ports to deal with failures

In every case where devices bind by PID, any such procedure becomes difficult or

impossible to execute without downtime.

In some cases, device drivers allow the user to manually specify persistent

bindings by PID. In these cases, such devices must be identified and an

appropriate update procedure created. If possible, the procedure should involve

changing from PID binding to WWN binding.
