System Module Descriptions 1 Table 1-4 System Module Descriptions (Continued) System Description Module RCS 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 RTWR (reliable transport write and read) to deliver the message. RCS also acts as a gatekeeper, limiting the number of outstanding requests for the Zoning, Security, or Management Server modules. RPCD The remote procedure call daemon (RPCD) is used by Fabric Access for API-related tasks. RTWR The reliable transport write and read daemon helps deliver data messages either to specific switches in the fabric or to all of the switches in the fabric. For example, if some of the switches are not reachable or are offline, RTWR returns an "unreachable" message to the caller, allowing the caller to take the appropriate action. If a switch is not responding, RTWR retries 100 times. SCN The internal state change notification daemon is used for state change notifications from the kernel to the daemons within Fabric OS. SEC The security daemon generates security errors, warnings, or information during security- related data management or fabric merge operations. Administrators should watch for these messages, to distinguish between internal switch and fabric operation errors, and external attack. SNMP Simple Network Management Protocol is a universally supported low-level protocol that allows simple get, get next, and set requests to go to the switch (acting as an SNMP agent). It also allows the switch to send traps to the defined and configured management station. Brocade switches support six management entities that can be configured to receive these traps. SS The supportSave command generates these error messages if problems are encountered. SULB The software upgrade library provides firmwareDownload command capability, which enables firmware upgrades to both CP blades with a single command, as well as nondisruptive code load to all 4.x switches. These messages might display if there are any problems during the firmwareDownload procedure. Most messages are informational only and are generated even during successful firmware download. For additional information, refer to the Fabric OS Administrator's Guide. SWCH These messages are generated by the switch driver module that manages a Fibre Channel switch instance. SYSC System controller is a daemon that starts up and shuts down all Fabric OS modules in the proper sequence. SYSM General system messages. TRCE RAS TRACE error messages.
