Fabric OS 5.x diagnostics and system error messages reference guide 93
PSWP The portswap feature and associated commands generate these error
messages.
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 <Italic>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.
