Updating Switches to the Core PID Addressing

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

Evaluate the Fabric

The fabric must be evaluated to:

■ Find any devices which bind to PIDs

■ Determine how each device driver will respond to the PID format change

■ Determine how any multi-pathing software will respond to a fabric service

interruption

If current details about the SAN are already available, it may be possible to skip

the Data Collection step. If not, it is necessary to collect information about each

device in the SAN. Any type of device may be able to bind by PID; each device

should be evaluated prior to attempting an online update. This information has

broad applicability, since PID-bound devices are not able to seamlessly perform in

many routine maintenance or failure scenarios.

Gathering Information

Collect Device, Software, Hardware, and Config Data

The following is a non-comprehensive list of information to collect:

■ HBA driver versions

■ Fabric OS versions

■ RAID array microcode versions

■ SCSI bridge code versions

■ JBOD drive firmware versions

■ Multi-pathing software versions

■ HBA time-out values

■ Multi-pathing software time-out values

■ Kernel time-out values

■ Configuration of switch
