Description
DAUTH error messages indicate problems with the 802.1x authentication module of the Fabric OS.
Error Checking and Correction (ECC) error messages indicate single-bit and multiple-bit errors in the
Dynamic Random Access Memory (DRAM) devices. ECC is a technology that helps to correct memory
errors.
The environmental monitor (EM) manages and monitors the various field-replaceable units (FRUs),
including the port cards, control processor (CP) blades, blower assemblies, power supplies, and
World Wide Name (WWN) cards. EM controls the state of the FRUs during system startup, hot-plug
sequences, and fault recovery.
EM provides access to and monitors the sensor and status data from the FRUs and maintains the
integrity of the system using the environmental and power policies. EM reflects system status by CLI
commands, system light emitting diodes (LEDs), and status and alarm messages. EM also manages
some component-related data.
Exchange Switch Support (ESS) error messages indicate problems with the ESS module of the Fabric
OS. ESS is an SW_ILS mechanism utilized by switches to exchange vendor and support information.
ESWCH error messages indicate problems with the Ethernet switch module of Fabric OS.
EVMD is the event management module.
FABRIC refers to a network of Fibre Channel switches. The FABRIC error messages come from the
fabric daemon. The fabric daemon follows the FC-SW-3 standard for the fabric initialization process,
such as determining the E_Ports, assigning unique domain IDs to switches, creating a spanning tree,
throttling the trunking process, and distributing the domain and alias lists to all switches in the
fabric.
Fabric OS system driver module.
Firmware blade compatibility errors with the control processor (CP).
Fibre Channel over IP port configuration messages.
Fibre Channel miscellaneous messages relate to problems with the physical layer used to send Fibre
Channel traffic to and from the switch.
FCoE error messages indicate problems with the FCoE module of the Fabric OS.
The Fibre Channel Protocol daemon is responsible for probing the devices attached to the loop port.
Probing is a process the switch uses to find the devices attached to the loop ports and to update the
Name Server with the information.
The Fibre Channel Physical Layer is used to send Fibre Channel traffic to and from the switch.
Fibre Channel router-related traffic and activity on the fabric or back-end fabric.
The FICN messages are generated during FICON emulation processing on an FCIP Tunnel.
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.
