H
halt
To stop a
, terminating all processes running in it. Halt is a processor
available
in both the
and the
. Halting a processor does not
affect any other processors in the system.
An error situation that stops a processor, terminating all processes running in it. If a processor
halts on its own, OSM issues an
such as Processor Software Halt.
Halted State
Services (HSS)
A millicode module that provides a maintenance interface when a processor is in the stopped
state. HSS is sometimes called boot millicode
hard reset
An action performed on an
HP NonStop™ Cluster Switch (model 6770)
and
that reinitializes the router-2 ASIC within the switch, disrupting
the routing of ServerNet messages through the switch for several minutes. When the hard reset
is finished, the paths are restored automatically.
hardware error
freeze (HEF)
A lock-step error that has caused a processor to freeze.
HP NonStop
Cluster Switch
(model 6770)
An assembly that routes ServerNet messages across an external fabric of a ServerNet cluster.
The cluster switch consists of a ServerNet II Switch, an uninterruptible power supply (UPS), and
AC transfer switch, and it can be packaged in a switch enclosure or in a 19-inch rack. The cluster
switch is used with star, split-star, and tri-star topologies.

HP NonStop
ServerNet Switch
(model 6780)
The cluster switch used in the layered topology. The 6780 switch consists of a switch logic board,
a midplane, plug-in cards, power supplies, and fans.

I
I/O adapter
module (IOAM)
A collection of modular components that provides I/O connectivity and can include ServerNet
switch boards, Fibre Channel ServerNet adapters (FCSAs), fans, and power supplies. In the
IOAM, each module is a logical entity that represents a single service domain.
I/O adapter
module enclosure
(IOAM enclosure)
The sheet-metal carrier that is installed in a standard 19-inch rack and contains the IOAM
components.
I/O controller
The hardware logic that controls computer I/O operations for a particular set of devices, such
as disks, tapes, terminals, or communications lines.

.
I/O enclosure
An HP NonStop S-series system enclosure containing one module, which includes ServerNet
adapters, disk drives, components related to the ServerNet fabrics, and components related to
electrical power and cooling for the enclosure.
I/O multifunction
(IOMF) 2 CRU
A
customer-replaceable unit (CRU)
that connects an I/O enclosure to a processor enclosure
through a ServerNet cable and supplies power to the components within the IOMF 2 CRU as
well as redundantly to the disk drives, SCSI terminators, and ServerNet adapters in that enclosure.
The IOMF2 CRU contains a
, service processor, a ServerNet router 2, an Ethernet
controller, three configurable ServerNet ports, and three SCSI ServerNet addressable controllers
(
) in a single unit.
incident report (IR)
A report sent by the OSM software on the
to the
on the OSM
. Incident reports notify you of changes that could directly affect the availability
of resources, changes in hardware configuration, and changes in software configuration.
If authorized, the OSM Notification Director forwards incident reports to your service provider.
The three types of incident reports are
software configuration reports
,
and
indicator lights
Two lights on a
or
that indicate the status of the unit as follows:
•
The green indicator light is lit when the unit has proper power applied.
•
The red or amber indicator light is lit when the unit is not working properly. During startup,
this light can indicate that the unit is not yet functioning.
