normalizing Normalizing is a state in which, block-for-block, data written by the
host to a mirrorset member is consistent with the data on other normal
and normalizing members. The normalizing state exists only after a
mirrorset is initialized. Therefore, no customer data is on the mirrorset.
normalizing
member
A mirrorset member whose contents are the same as all other normal
and normalizing members for data that has been written since the
mirrorset was created or lost cache data was cleared. A normalizing
member is created by a normal member when either all of the normal
members fail or all of the normal members are removed from the
mirrorset. See also copying member.
NVM Non-Volatile Memory. A type of memory where the contents survive
power loss. Also sometimes referred to as NVMEM.
OCP Operator control panel. The control or indicator panel associated with a
device. The OCP is usually mounted on the device and is accessible to
the operator.
offset A relative address referenced from the base element address. Event
Sense Data Response Templates use offsets to identify various
information contained within one byte of memory (bits 0 through 7).
other controller The controller in a dual-redundant pair that is connected to the
controller serving the 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 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.
