Each non-global zone has its own section of the file system hierarchy in the zone root directory. Processes running in the zone can access files only within the zone root.
You can set the zone root in two ways:
Setting the zone root on shared storage means you need install the non-global zone on shared storage from one system only. The non-global zone and the zone root can fail over to the other systems. To do this, the system software, including the patches, must be identical on each system during the existence of the zone.
