Updating Switches to the Core PID Addressing

Evaluate the Fabric

The fabric must be evaluated to:
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:

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

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
