HP StorageWorks XPath OS 7.4.X System Error Messages Reference Guide (AA-RVHGC-TE, September 2005)

14 Introduction to system error messages
Event log
View this log using the eventShow command. It displays system events, such as port up, port down, link
events, fabric segmentations, and logins. Events from this log are dumped into the error log as well. Use
the eventSeverityShow command to view the possible events in the event log, as well as the default
severity levels for those events.
In the XPath OS, only specified event messages (persistent events) are saved in nonvolatile memory and
restored to the event log after a reboot or power cycle.
Use the eventActionShow command to view the events that are saved to nonvolatile memory. The
events saved to nonvolatile memory are labeled persistent. You can use the eventActionSet command
to customize which events are saved in nonvolatile memory and which are not. A total of 128 messages
can be saved in nonvolatile memory. These messages are saved in a circular buffer; once the message limit
is reached, new messages delete the oldest messages.
Table 3 describes the event log commands. See the HP StorageWorks XPath OS 7.4.x command reference
guide for detailed information on these commands.
Port log
View this log using the portLogShow or portLogDump commands. It displays port events, such as, port
down, link events, and fabric segmentations. Events from this log are for information only. ”Port log
messages” on page 107 lists messages from the port logs.
Use the commands in Table 4 to view and manage port logs.
Message severity levels
There are six severity levels for messages, ranging from Panic to Debug. The definitions in Table 5 can be
used as general guidelines for troubleshooting. Make sure to review each error message description
thoroughly before taking action.
