1 System module descriptions TABLE 6 System module MS MSTP NBFS NS NSM ONMD PDM PDTR PLAT PMGR PORT PS PSWP RAS RCS RMON RPCD System module descriptions (Continued) Description The Management Service enables the user to obtain information about the Fibre Channel fabric topology and attributes by providing a single management access point. MS provides for both monitoring and control of the following areas: • Fabric Configuration Server: Provides for the configuration management of the fabric. • Unzoned Name Server: Provides access to Name Server information that is not subject to zone constraints. • Fabric Zone Server: Provides access to and control of zone information. MSTP error messages indicate problems with Multiple Spanning Tree Protocol modules of the Fabric OS. NBFSM is a part of the Fabric Shortest Path First (FSPF) protocol that handles a neighboring or adjacent switch's finite state machine (FSM). Input to the FSM changes the local switch from one state to another, based on specific events. For example, when two switches are connected to each other using an interswitch link (ISL) cable, they are in the Init state. After both switches receive HELLO messages, they move to the Database Exchange state, and so on. NBFSM states are Down (0), Init (1), Database Exchange (2), Database Acknowledge Wait (3), Database Wait (4), and Full (5). Indicates problems with the simple Name Server module. NSM error messages indicate problems with the Interface Management and VLAN Management module of the Fabric OS. ONMD error messages indicate problems with the Operation, Administration and Maintenance module of the Fabric OS. Parity data manager (PDM) is a user-space daemon responsible for the replication of persistent configuration files from the primary partition to the secondary partition and from the active CP blade to the standby CP blade. PDTR messages indicate panic dump trace files have been created. PLAT messages indicate hardware problems. A group of messages relating to logical switch creation, deletion, and configuration. PORT error messages refer to the front-end user ports on the switch. Front-end user ports are directly accessible by users to connect end devices or connect to other switches. The performance server daemon measures the amount of traffic between endpoints or traffic with particular frame formats, such as SCSI frames, IP frames, and customer-defined frames. The portswap feature and associated commands generate these error messages. Informational messages when first failure data capture (FFDC) events are logged to the FFDC log and size or roll-over warning. The reliable commit service daemon generates log entries when it receives a request from the zoning, security, or management server for passing data messages to switches in the fabric. RCS then requests reliable transport write and read (RTWR) to deliver the message. RCS also acts as a gatekeeper, limiting the number of outstanding requests for the Zoning, Security, or Management Server modules. RMON messages are error or informational messages pertaining to the RMOND daemon. The remote procedure call daemon (RPCD) is used by Fabric Access for API-related tasks. 32 Brocade Fabric OS Message Reference 53-1004119-01
