The Oracle FS Path Manager (FSPM) software uses HP-UX native multipathing to communicate with Oracle FS System servers along different pathways.
For information about HP-UX 11i v3 native multipathing, refer to the white paper Native Multi-Pathing for Mass Storage (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01906512/c01906512.pdf).
FSPM communicates with Oracle FS System servers along two separate paths: the control path and the data path. The FSPM daemon uses the control path to manage path communication, and FSPM works with the HP-UX native multipathing framework to manage the LUN data access paths.
