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 FW is the Fabric Watch module. This 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 HAM is a user space daemon responsible for high availability
management.
HAMK This is the kernel module for the HAM daemon.
HIL Hardware independent layer.
HLO HLO is a part of FSPF protocol that handles the HELLO protocol between
adjacent switches. The HELLO protocol is used to establish connectivity with
a neighbor switch, to establish the identity of the neighbor switch, and to
exchange FSPF parameters and capabilities.
HMON Health monitor.
HTTP HTTP error message.
KSWD • The kernel software watchdog (KSWD) watches daemons for unexpected
terminations and “hang” conditions and informs the HAM module to
take corrective actions such as failover or reboot.
• The following daemons are monitored by KSWD:
• Diagnostics daemon (DIAGD)
• Environment monitor daemon (EMD)
• EVM daemon (EVMD)
• Fabric daemon (FABRICD)
• FCPD daemon (FCPD)
• FDMI daemon (FDMID)
• FICON-CUP daemon (FICUD)
• FSPF daemon (FSPFD)
• Fabric watch daemon (FWD)
• Management Server daemon (MSD)
• Name Server daemon (NSD)
• PDM daemon (PDMD)
• PS daemon (PSD)
• Reliable commit service daemon (RCSD)
• FA-API RPC daemon (RPCD)
• Security daemon (SECD)
• SNMP daemon (SNMPD)
• Track changes daemon (TRACK_CHANGES)
• Time Service daemon (TSD)
• Web Tools daemon (WEBD)
• Zone daemon (ZONED)
