1 System Module Descriptions Table 1-4 System Module Descriptions (Continued) System Description Module LSDB The link state database is a part of the FSPF protocol that maintains records on the status of port links. This database is used to route frames. MFIC MS-FICON messages relate to FICON installations. FICON-CUP messages are displayed under the FICU module. MPTH Multicast path uses the shortest path first (SPF) algorithm to dynamically compute a broadcast tree. MQ Message queues are used for interprocess communication. Message queues allow many messages, each of variable length, to be queued. Any process or interrupt service routine (ISR) can write messages to a message queue. Any process can read messages from a message queue. MS 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. NBFS NBFSM is a part of the FSPF (fabric shortest path first) 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 ISL (interswitch link) 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). NS Indicates problems with the Simple Name Server module. PDM Parity data manager 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 These messages indicate panic dump trace files have been created. PLAT This message indicates hardware problems. PORT 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. PS The performance server daemon measures the amount of traffic between end points or traffic with particular frame formats, such as SCSI frames, IP frames, and customer- defined frames. PSWP The portswap feature and associated commands generate these error messages. RAS First failure data capture (FFDC), informational message when FFDC events are logged to the FFDC log and size/roll over warning. 1-18 Fabric OS Message Reference Publication Number: 53-1000242-01
