drive blank

A carrier that is required to control airflow within the enclosure whenever

 

 

there is less than a full complement of disk drives in an enclosure. The

 

 

only function of a passive drive blank is to control airflow within the disk

 

 

enclosure.

dual power

See redundant power configuration.

element

An object in an enclosure such as an EMU, power supply, disk, fan, I/O

 

 

module, and so forth. The object can be controlled, interrogated, or

 

 

described by the enclosure services process.

EMU

 

Environmental monitoring unit. An element which monitors the status of

 

 

an enclosure including the power, air temperature, fan status, and so forth.

 

 

It detects problems and displays and reports these conditions to the user

 

 

and the controller. In some cases, corrective actions are implemented.

enclosure

A chassis containing a set of disk drives, power supplies, fans, an EMU,

 

 

I/O modules, and so forth.

fan

 

An airflow element mounted in a StorageWorks enclosure.

host

 

The primary or controlling computer (in a multiple computer network) to

 

 

which storage is attached.

hot-pluggable

An element that can be replaced without removing power from the

 

 

enclosure.

 

 

 

 

 

 

 

CAUTION: If removing the element interrupts the SCSI bus you

 

 

 

cannot use this method. You must quiesce the bus and use the

 

 

 

pluggable replacement method.

 

 

 

 

 

 

 

NOTE: The array controller must support this replacement method.

I/O module

An element that integrates the enclosure bus with either an 8-bit

 

 

single-ended, 16-bit single-ended, or 16-bit differential SCSI bus.

LED

 

Light emitting diode. A diode that illuminates to define the status. The

 

 

standard states are ON, OFF, or FLASHING.
