Description
SSMD error messages indicate problems with the System Services Module of the Fabric OS.
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 Fabric OS 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.
These messages are generated by the switch driver module that manages a Fibre Channel switch
instance.
System controller is a daemon that starts up and shuts down all Fabric OS modules in the proper
sequence.
General system messages.
A kernel-space driver that handles all I/O operations aimed at Tape containers.
RAS TRACE error messages.
The track change feature tracks the following events:
•
Turning on or off the track change feature
•
CONFIG_CHANGE
•
LOGIN
•
LOGOUT
•
FAILED_LOGIN
If any of these events occur, a message is sent to the system message log. Additionally, if the SNMP
trap option is enabled, an SNMP trap is also sent.
For information on configuring the track change feature, refer to the Fabric OS Command Reference
or the Fabric OS Administrator's Guide.
Time Service provides fabric time-synchronization by synchronizing all clocks in the fabric to the
clock time on the principal switch.
UCST is a part of the Fabric Shortest Path First (FSPF) protocol that manages the Unicast routing
table.
UPATH is a part of the FSPF protocol that uses the SPF algorithm to dynamically compute a Unicast
tree.
VDR messages indicate Field-Programmable Gate Array (FPGA) parity errors.
The VS module messages indicate any problems or information associated with the Dynamic Fabric
Provisioning feature, including commands associated with the fapwwn command and
configurations.
Indicates problems with the Web Tools module.
XTUN messages are generated by the FCIP Tunnel implementation. These messages indicate status
of FCIP tunnels, FCIP emulation events for FCP traffic, or FCIP debug information (FTRACE buffer
status changes).
Zeus error messages indicate problems with the Zeus driver module.
The zone module messages indicate any problems associated with the zoning features, including
commands associated with aliases, zones, and configurations.
