PKI Public key infrastructure. An infrastructure that is based on public key cryptography and CA
(certificate authority) and that uses digital certificates. See also CA,
key
PKI certification Public key infrastructure certification utility. A utility that makes it possible to collect certificate
utility requests from switches and to load certificates to switches. See also
PLDA Private loop direct-attached. A technical report specifying a logical loop.
PLOGI Port login. The port-to-port login process by which initiators establish sessions with targets. See
also FLOGI.
point-to-point A Fibre Channel topology that employs direct links between each pair of communicating
entities. See also topology.
port In an HP StorageWorks switch environment, an SFP or GBIC receptacle on a switch to which
an optic cable for another device is attached.
port address In Fibre Channel technology, the port address is defined in hexadecimal. In the HP Fabric OS,
a port address can be defined by a domain and port number combination or by area number.
In an ESCON Director, an address used to specify port connectivity parameters and to assign
link addresses for attached channels and control units.
port card A hardware component that provides a platform for field-replaceable, hot swappable ports.
port log A record of all activity on a switch, kept in volatile memory.
port log dump A view of what happens on a switch, from the switch's point of view. The
command is used to read the port log.
port name A user-defined alphanumeric name for a port.
port swapping Port swapping is the ability to redirect a failed port to another port. This feature is available in
Fabric OS v4.1.0 and higher.
port_name The unique identifier assigned to a Fibre Channel port. Communicated during login and port
discovery.
POST Power-on self-test. A series of tests run by a switch after it is turned on.
PPP Point-to-Point Protocol.
primary FCS switch Relates to the HP Secure Fabric OS feature. The primary fabric configuration server switch
actively manages security and configurations for all switches in the fabric. See also
fabric, FCS switch.
primitive sequence An ordered set that is transmitted repeatedly and continuously. Primitive sequences are
transmitted to indicate specific conditions within or conditions encountered by the receiver
logic of an FC_Port. See
primitive signals An ordered set that indicates actions or events and requires just one occurrence to trigger a
response. IDLE and R_RDY are used in all three topologies: ARB, OPN, and CLS. MRK is used
in arbitrated loop.
principal switch The first switch to boot up in a fabric. Ensures unique domain IDs among roles.
private device A device that supports arbitrated-loop protocol and can interpret 8-bit addresses but cannot
log in to the fabric.
private key The secret half of a key pair. See also key,
cryptography.
OLS and NOS.
