System Module Descriptions
1
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 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.
RKD These messages are either error or informational messages pertaining to the Rekey daemon of the
Fabric OS.
RMOND RMOND messages are error or informational messages pertaining to the RMOND daemon.
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.
SAS Storage application services supporting director-class storage virtualization platform.
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.
SPC SPC messages indicate problems and informational updates associated with the security processor.
These messages could be tiggered by the following three modules: Security processor controller, SP
system controller and SP Keyapp.
SPM Error messages indicating problems either with key or SP management.
SS The supportSave command generates these error messages if problems are encountered.
SSM SSM error messages indicate problems with the System Services Module of the Fabric OS.
SULB The software upgrade library provides the 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.
TAPE A kernel-space driver that handles all I/O operations aimed at tape containers.
TRCE RAS TRACE error messages.
