Command Line Interface Reference Guide
synchronous
Pertaining to a method of data transmission which allows each event to operate in relation
to a timing signal. See also asynchronous.
tape
A storage device supporting sequential access to variable sized data records.
target
(1) A SCSI device that performs an operation requested by an initiator. (2) Designates the
target identification (ID) number of the device.
target ID number
The address a bus initiator uses to connect with a bus target. Each bus target is assigned a
unique target address.
this controller
The controller that is serving your current CLI session through a local or remote terminal.
See also other controller.
TILX
Tape inline exerciser. The controller diagnostic software to test the data transfer capabilities
of tape drives in a way that simulates a high level of user activity.
topology
An interconnection scheme that allows multiple Fibre Channel ports to communicate with
each other. For example, point-to-point, Arbitrated Loop, and switched fabric are all Fibre
Channel topologies.
transfer data rate
The speed at which data can be exchanged with the central processor, expressed in
thousands of bytes per second.
transparent failover
Keeps the storage array available to the host(s) by allowing the surviving controller of a
dual redundant pair to take over total control of the subsystem and is transparent (invisible)
to the host(s).
ULP
Upper Layer Protocol.
ULP process
A function executing within a Fibre Channel node which conforms to the ULP requirements
interacting with other ULP processes.
Ultra SCSI bus
A Fast-20 SCSI bus. See also Wide Ultra SCSI.
