1 System Module Descriptions TABLE 5 System Module KSWD KTRC LOG LSDB MFIC MPTH MQ System Module Descriptions (Continued) Description The kernel software watchdog (KSWD) watches daemons for unexpected terminations and "hang" conditions and informs the HAM module to take corrective actions such as failover or reboot. The following daemons are monitored by KSWD: • Access Gateway daemon (agd) • Alias Server (asd) • ARR daemon (arrd) • Authentication daemon (authd) • Blade Manager (bmd) • Common Access Layer (cald) • Diagnostics daemon (diagd) • Environment Monitor (emd) • EVM daemon (evmd) • Exchange Service Support daemon (essd) • FA-API rpc daemon (rpcd) • Fabric daemon (fabricd) • Fabric Watch daemon (fwd) • FCPD daemon (fcpd) • FDMI daemon (fdmid) • FICON CUP daemon (ficud) • FSPF daemon (fspfd) • Inter-fabric Routing daemon (iswitchd) • IP Storage Daemon (ipsd) • iSCSI daemon on CP (icpd) • iSNS client daemon on CP (isnscd) • Management Server daemon (msd) • Name Server Daemon (nsd) • PDM daemon (pdmd) • PS daemon (psd) • RASLOG daemon (raslogd) • RSC daemon (rcsd) • SAS CP Daemon (scpd) • Security daemon (secd) • SNMP daemon (snmpd) • Time Service daemon (tsd) • TRACE daemon (traced) • Track Changes daemon (trackd) • Web tools daemon (webd) Kernel RAS trace module. RASLog subsystem. 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. MS-FICON messages relate to fibre connectivity (FICON) installations. Fibre connectivity control unit port (FICON-CUP) messages are displayed under the FICU module. Multicast path uses the shortest path first (SPF) algorithm to dynamically compute a broadcast tree. 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. 16 Fabric OS Message Reference 53-1000437-01
