HP 3PAR Upgrade Pre-Planning Guide

Local HP 3PAR OS Upgrades
Local HP 3PAR OS upgrades are achieved by utilizing an on-site service representative to perform
the upgrade. Typically, local HP 3PAR OS upgrades are performed when there is no remote
connection to the service processor. Additionally, a local HP 3PAR OS upgrade may be combined
with other on-site activities, such as hardware upgrades or maintenance.
