Halted State Services Millicode
H-series systems. For firmware details, see the H06.03 Software Installation and
Upgrade Guide.
Halted State Services Millicode
The halted-state services (HSS) millicode (T0287) on the Integrity NonStop NS-series
system replaces the NonStop S-series processor boot millicode. It provides low-level
exception handling, support for NonStop system boot, processor reload, interfaces for
debugging a down processor using the processor-switch maintenance entity, and
support for memory dump.
Maintenance Entity
Processor Switch Maintenance Entity
The processor switch maintenance entity provides maintenance and diagnostic
functionality for TNS/E systems. The associated microprocessor firmware resides in all
processor switch maintenance entities found in the system.
A TNS/E system comprises a pair of processor switch modules (one per fabric). The
processor switch modules connect via the ServerNet product to logical TNS/E
processors 0-15. Each processor switch module includes processor switch
maintenance entity firmware and provides systemwide maintenance functionality.
Maintenance Entity for IOAM
The maintenance entity for the I/O adapter module (IOAM) supports the connection to
processor switches, making Fibre Channel ServerNet adapter (FCSA) and Gigabit
Ethernet 4-port ServerNet adapter (G4SA) functionality available on a TNS/E platform.
The service processor (SP) supports connection of legacy IOMF enclosures to a
processor switch, providing the TNS/E platform with connectivity to S-series legacy
input/output controllers (IOCs) and storage.
SCF
•
For Integrity NonStop NS-series disk drive enclosures, the Fibre Channel Storage
Monitor process:
°
Monitors environmental limits
°
Tracks and reports hardware changes
°
Issues control commands to the environmental monitoring unit (EMU)
You can use the Subsystem Control Facility (SCF) STATUS and INFO commands
to display different types of information about the FCS Monitor process:
°
The STATUS command displays dynamic state information about FCSMON.
°
The INFO PROCESS command displays attributes of the FCSMON process.
