234. y A Some older device drivers behave as if a PID uniquely identifies a device These device drivers should be updated if possible to use WWN binding instead A device s WWN never changes unlike its PID PID binding creates problems in many routine maintenance scenarios and should always be avoided Fortunately very few device drivers still behave this way and these are expected to be updated as well Many current device drivers enable binding by PID Only select this method if there is a compelling reason and only after you have evaluated the impact of doing so Q Must I schedule downtime for my SAN to perform the PID update A Only if you do not have dual fabrics or have devices that bind by PID Q Must I stop all traffic on the SAN before performing the update A If you are running dual fabrics with multi pathing software you can update one fabric at a time Move all traffic onto one fabric in the SAN update the other fabric move the traffic onto the updated fabric and update the final fabric Without dual fabrics stopping traffic is highly recommended This is the case for many routine maintenance situations so dual fabrics are always recommended for uptime sensitive environments Q How can I avoid having to change PID formats on fabrics in the future A The core PID format can be proactively set on a fabric at initial installation The update could also be opportunistically combined with any scheduled outage Setting the
