HP 3PAR OS Persistent Ports Setup and Connectivity Guidelines for FCoE
Starting with HP 3PAR OS 3.1.3, the HP 3PAR OS Persistent Ports feature is supported for FCoE
target ports (FCoE end-to-end configurations).
Starting with HP 3PAR OS 3.1.3 software and above, the HP 3PAR OS Persistent Ports feature is
enabled by default for HP 3PAR StoreServ Storage FCoE ports during node-down events.
Specific cabling setup and connectivity guidelines need to be followed for HP 3PAR OS Persistent
Ports to function properly. Key elements for the HP 3PAR OS Persistent Ports feature setup and
connectivity are:
• HP 3PAR StoreServ Storage FCoE partner ports must be connected to the same FCoE network.
• The same CNA port on host-facing HBAs in the nodes of a node pair must be connected to
the same FCoE network, and preferably to different FCoE switches on the network.
• The FCoE network being used must support NPIV, and NPIV must be enabled.
