System module descriptions
1
CCFG CCFG error messages indicate problems with the Converged Enhanced Ethernet (CEE) configuration
module of the Fabric OS.
CDR Driver error messages.
CHS Error messages reporting the problems in the management of the blades in the different slots of the
chassis.
CNM Cluster Node Manager (CNM) is a software daemon module of the Fabric OS. The messages from
CNM are problems encountered by CNM, warnings, or information to the user of events.
CONF Status messages for configUpload and configDownload operations.
CTAP A user-space daemon that forwards non-performance-critical messages from the TAPE driver to the
Crypto Virtual LUN Controller (CVLC) and Security Processor (SP), and vice versa. This module also
maintains a cache of recently acquired keys, reducing requests to the key vault itself.
CVLC Crypto Virtual LUN Controller (CVLC) is a software module running on blade FOS (BFOS). The
messages of CVLC are problems encountered by CVLC, warnings to alert the user, or information to
the user.
CVLM Crypto Virtual LUN Manager (CVLM) is a software module of the Fabric OS. The messages of CVLM
are problems encountered by CVLM, warnings to alert the user, or information to the user.
DOT1 DOT1 error messages indicate problems with the 802.1x authentication module of the Fabric OS.
ECC 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.
EM 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.
ESS 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.
ESW ESW error messages indicate problems with the Ethernet switch module of Fabric OS.
EVMD EVMD is the event management module.
FABR FABRIC refers to a network of Fibre Channel switches. The FABR 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.
FABS Fabric OS system driver module.
FBC Firmware blade compatibility errors with the control processor (CP).
FCMC Fibre Channel miscellaneous messages relate to problems with the physical layer used to send Fibre
Channel traffic to and from the switch.
FCOE FCoE error messages indicate problems with the FCoE module of the Fabric OS.
