System module descriptions 1 TABLE 6 System module ECC EM ESS ESW EVMD FABR FABS FBC FCMC FCOE FCPD FCPH FCR FICN FICU FKLB FLOD FSPF System module descriptions (Continued) Description 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. ESW 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 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. Fabric OS system driver module. Firmware blade compatibility errors with the control processor (CP). 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.
