Features and benefits: With the release of HP 3PAR OS version 3.1.2, HP has introduced new

functionality called “Persistent Ports” that supports non disruptive online software upgrades and
recovery from node failures, in a manner that is transparent to any FC fabric connected host
accessing the HP 3PAR StoreServ.
The Server HBA ports may be zoned to only a single array Node’s port WWN or it may be zoned
to both.
