Normal member
A mirrorset member that, block-for-block, contains the same data as other Normal members
within the mirrorset. Read requests from the host are always satisfied by Normal members.
normalizing
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 was written since the mirrorset was created or lost cache data was
cleared. A Normalizing member is created by a Normal member after either all of the
Normal members fail or all of the Normal members are removed from the mirrorset.
See also Copying member.
NVM
Nonvolatile memory. A type of memory where the contents survive power loss. Also called
NVMEM. The NVMEM in the controller stores the configuration parameters for the
storage subsystem.
OCP
Operator control panel. The control and indicator panel associated with an array controller.
The OCP is mounted on the controller 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).
operator control panel
See OCP.
other controller
The controller in a dual-redundant pair that is connected to the controller serving a 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, a bit)
of each byte is sent or received simultaneously.
