halt To stop a processor, terminating all processes running in it. Halt is a processor action available

in both the OSM Low-Level Link and the OSM Service Connection. 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 alarm 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 HP NonStop™

ServerNet Switch (model 6780) 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.

See also HP NonStop ServerNet Switch (model 6780).

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.

See also HP NonStop Cluster Switch (model 6770).

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.

See also ServerNet addressable controller (SAC).

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 power supply, service processor, a ServerNet router 2, an Ethernet

controller, three configurable ServerNet ports, and three SCSI ServerNet addressable controllers

(S-SACs) in a single unit.

incident report (IR) A report sent by the OSM software on the server to the OSM Notification Director on the OSM

system console. 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 problem incident reports, software configuration reports,

and periodic incident reports.

indicator lights Two lights on a CRU or FRU 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.
