The Fault Manager runs in the background on each server. It records, in the error log, faults detected by the XSCF, and initiates proactive self-healing activities, such as disabling faulty components. The Fault Manager maintains two sets of logs for use by system administrators and service personnel: Error log Records error telemetry, the symptoms of problems detected by the system Fault log Records fault diagnosis information; the problems believed to explain these symptoms. By default, fmdump displays the contents of the fault log, which records the result of each diagnosis made by the fault manager or one of its component modules. Each problem recorded in the fault log is identified by: ■ The time of its diagnosis ■ A Universal Unique Identifier (UUID) that can be used to uniquely identify this particular problem across any set of systems ■ A message identifier (MSG-ID) that can be used to access a corresponding knowledge article located at the specified website. If a problem requires action by a system administrator or service personnel or affects system behavior, the Fault Manager also issues a human-readable message. This message provides a summary of the problem and a reference to the knowledge article on the specified website. You can use the -v and -V options to expand the display from a single-line summary to increased levels of detail for each event recorded in the log. You can also use the -M option to display only one screen at a time. The -c, -t, -T, and -u options can be used to filter the output by selecting only those events that match the specified class, range of times, or uuid. If more than one filter option is present on the command line, the options combine to display only those events that are selected by the logical AND of the options. If more than one instance of the same System Administration 61 fmdump(8) Privileges OPTIONS filter option is present on the command-line, the like options combine to display any events selected by the logical OR of the options. You can use the -m option to display the Fault Manager syslog contents. You must have platop, platadm, or fieldeng privileges to run this command. Refer to setprivileges(8) for more information. The following options are supported. -c class Selects events that match the specified class. The class argument can use the global pattern matching syntax, which is similar to global pattern matching for files. For example xyz.* would match xyz.sxc and xyz.pdf. The class represents a hierarchical classification string indicating the type of telemetry event. -h Displays usage statement. When used with other options or operands, an error occurs. -e Displays events from the fault management error log instead of the fault log. The error log contains private telemetry information used by XSCF's automated diagnosis software. This information is recorded to facilitate post-mortem analysis of problems and event replay, and should not be parsed or relied upon for the development of scripts and other tools. -f Displays only lines that have been appended to the dump file since the command was executed. Output continues until interrupted by Ctrl-C. -m Displays the Fault Manager syslog message contents. -M Displays text by page. This option provides a function that is the same as that of the more command. -t time Selects events that occurred at or after the specified time. The time can be specified using the forms in the Time Formats following this section. Used with -T you can specify a range. -T time Selects events that occurred at or before the specified time. time can be specified using any of the time formats described for the -t option. Used with -t you can specify a range. 62 SPARC Enterprise Mx000 Servers XSCF Reference Manual • Last Revised September 2008 fmdump(8) -u uuid Selects fault diagnosis events that exactly match the specified uuid. Each diagnosis is associated with a UUID for identification purposes. The -u option can be combined with other options such as -v to show all of the details associated with a particular diagnosis. If the -e option and -u option are specified at the same time, fmdump displays the relevant error events. -v Displays verbose event detail. The event display is enlarged to show additional common members of the selected events. -V Displays very verbose event detail. The event display is enlarged to show every member of the name-value pair list associated with each event. In addition, for fault logs, the event display includes a list of cross-references to the corresponding errors that were associated with the diagnosis. The following are the Time Formats: Time Format Description mm/dd/yy hh :mm : ss Month, day, year, hour in 24-hour format, minute, and second. Any amount of whitespace can separate the date and time. The argument should be quoted so that the shell interprets the two strings as a single argument. mm/dd/yy hh:mm Month, day, year, hour in 24-hour fo...
