HP StorageWorks Fabric OS 5.0.0 Diagnostics and System Error Messages Reference Guide (AA-RW1SA-TE, May 2005)

40 Introduction to system messages
FSS The Fabric OS state synchronization framework provides
facilities by which the active CP can synchronize with the
standby CP, enabling the standby CP to take control of the
switch non-disruptively during failures and software
upgrades. These facilities include version negotiation, state
information transfer, and internal synchronization functions,
enabling the transition from standby to active operation.
FSS is defined both as a component and a service. A
component is a module in Fabric OS, implementing a
related set of functionality. A service is a collection of
components grouped together to achieve a modular
software architecture.
FSSM The Fabric OS state synchronization management module
is defined both as a component and a service. A
component is a module in Fabric OS implementing a
related set of functionality. A service is a collection of
components grouped together to achieve a modular
software architecture.
FW The Fabric Watch module monitors thresholds for many
switch subsystems: for example, temperature, voltage, fan
speed, and switch status. Any changes that cross a
specified threshold are reported to the system message log.
HAM A user space daemon responsible for high-availability
management.
HAMK The kernel module for the HAM daemon.
HIL Hardware Independent Layer.
HLO Part of FSPF protocol that handles the HELLO protocol
between adjacent switches. The HELLO protocol establishes
connectivity with a neighbor switch to determine the identity
of the neighbor switch and to exchange FSPF parameters
and capabilities.
HMON Health monitor.
HTTP HTTP error message.
