id
SCSI target ID default address for the Multivendor EMU.
See also SCSI target ID.
ID
Identifier. As used in SCSI bus ID, SCSI ID or device ID.

See ID.
input/output
See I/O module.

LED
Light-emitting diode. A semiconductor diode that emits light when voltage is
applied. Typically used on indicator panels to display an operating status.

maintenance
The operator terminal used to identify an HS-family controller, to enable its
terminal
host paths, to define its subsystem configuration, and to check its status. The
HS-family maintenance terminal accepts any terminal conforming to
EIA–423. Use the maintenance terminal to configure a storage subsystem.
MB/s
Megabytes per second. The per second byte transfer rate with a binary
multiplier of 1,024,000.
The bus width (8- or 16-bit), the number of bytes per word (1 or 2,
respectively), and the bus clock frequency determines the transfer rate in
MB/s.
megabytes per
See MB/s.
second
node
A SCSI bus target or initiator that uses a SCSI bus ID. For example, disk
drives, tape drives, array controllers, and adapters all have a SCSI bus ID and
are nodes. Hubs, expanders, and converters are devices and do not have a
SCSI bus ID.
An Ultra SCSI bus can have a maximum of 16 nodes (SCSI bus addresses 0
through 15).
A narrow bus can have a maximum of eight nodes (SCSI bus addresses 0
through 7).
overtemperature
A condition where the temperature is above a specified limit and can cause
equipment failure if not corrected.
