Description
The FICON-CUP daemon handles communication with fibre connectivity (FICON) on IBM FICON
storage devices. Errors to this module are usually initiation errors or indications that FICON-CUP
prerequisites have not been met, such as a license key, core process ID (PID), and secure mode on
the fabric.
Fabric OS I/O kernel library module.
FLOD is a part of the fabric shortest path first (FSPF) protocol that handles synchronization of the link
state database (LSDB) and propagation of the link state records (LSRs).
Fabric shortest path first (FSPF) is a link state routing protocol that is used to determine how frames
should be routed. These messages are about protocol errors.
The Fabric OS state synchronization framework provides facilities by which the active control
processor (CP) can synchronize with the standby CP, enabling the standby CP to take control of the
switch nondisruptively 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 the Fabric OS,
implementing a related set of functionality. A service is a collection of components grouped together
to achieve a modular software architecture.
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 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 is a user space daemon responsible for high availability management.
This is the kernel module for the high availability management (HAM) daemon.
Hardware independent layer.
HLO is a part of the fabric shortest path first (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.
Health monitor.
HTTP error messages.
This raslog generates messages related to port restart failure.
IBPD stands for iSCSI gateway daemon on a blade processor (BP). It manages iSCSI initiator access
control, session authentication, and session/connection statistics.
ICPD stands for iSCSI gateway daemon on a control processor (CP). It manages iSCSI configurations
such as CHAP, VT/LUN, DD/DDSet and portal configurations, and statistics such as iSCSI
session/connection information. Moreover, ICPD distributes iSCSI configurations not only switch
wide, but also fabric wide. It keeps track iSCSI VT status and updates VT status to BP.
System messages generated by the IP admin demon.
Fibre Channel over IP license, tunneling, and port related messages.
The ISCS module is the FabOS component that performs system-level control of the iSCSI Gateways.
Its functions include: initialization, message delivery from iSCSI protocol clients, system error
monitoring, and fault recovery.
ISNS server and client status messages.
