HP StorageWorks MSA 2.8 SAN Switch - Manual (Page 148)

Updating Switches to the Core PID Addressing

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
