Each WPAR has its own section of the file system hierarchy in the WPAR root directory. Processes that run in the WPAR can access files only within the WPAR root.
You can set the WPAR root in the following two ways:
WPAR root on local storage.
In this configuration, you must create a WPAR on each node in the cluster.
WPAR root on NFS.
In this configuration, create a WPAR on the NFS storage. You need to duplicate the WPAR configuration across all the nodes in the cluster.
When you set the WPAR root on NFS, install the WPAR from one node only. The WPAR root can fail over to the other nodes in the cluster. The system software, including the patches, must be identical on each node during the existence of the WPAR.
