Glossary
other controller
The controller in a dual-redundant pair that is connected to the controller serving your current
CLI session. See also "this controller."
outbound fiber
One fiber in a link that carries information away from a port.
parallel data transmission
A data communication technique in which more than one code element (for example, bit) of
each byte is sent or received simultaneously.
parity
A method of checking if binary numbers or characters are correct by counting the ONE bits. In
odd parity, the total number of ONE bits must be odd; in even parity, the total number of ONE
bits must be even. Parity information can be used to correct corrupted data. RAIDsets use
parity to improve the availability of data.
parity bit
A binary digit added to a group of bits that checks to see if errors exist in the transmission.
parity check
A method of detecting errors when data is sent over a communications line. With even parity,
the number of ones in a set of binary data should be even. With odd parity, the number of ones
should be odd.
parity RAID
See RAIDset
participating mode
A mode within an L_Port that allows the port to participate in loop activities. A port must have
a valid AL_PA to be in participating mode.
partition
A logical division of a container represented to the host as a logical unit.
PCMCIA
Personal Computer Memory Card Industry Association. An international association formed
to promote a common standard for PC card-based peripherals to be plugged into notebook
computers. The card, commonly known as a PCMCIA card or program card, is about the size
of a credit card. See also program card.
