The command causes the SDG Router to run an immediate, level 4 health
check. Results display that indicate which devices or subsystems failed the
check.
Router> hlthChkNow
loggerDump [number]
The loggerDump command dumps records from the system event log to
the console. You can use a numeric parameter to indicate the number of
events to display. With no parameter specified, all events in the log file
display starting with the most recent events, as the following example
shows.
Router > loggerDump 4
*** Dumping 4 (1018 through 1021) of 1021 records ***
000008 1018 0d:00h:00m:07s:22t -- SCSI 2: Bus RESET
000009 1019 0d:00h:00m:07s:22t -- Target device added: index 0, handle 0xc0ec2600
000010 1020 0d:00h:00m:08s:18t -- Target device added: index 10, handle 0xc0ad2590
000011 1021 0d:00h:00m:08s:28t -- SCSI 2: New Device at Id 6, Lun 0
Router >
loggerDumpCurrent [level]
The loggerDumpCurrent command dumps records from the system event
log to the console. Only the records that were logged since the system was
last started are dumped. Level specifies the event log level for the events
as shown in Table 54.
Table 54. SDG Router event log levels
Level Name Explanation
0 Private Events that are never shown by the remote event
viewer but are recorded in the SDG Router event
log
1 Notice Conditions that should always be reported, such
as temperature alarms and device removals
2 Warning Events that might result in a later problem
3 Information Events that are not errors or warnings
The following example shows a dump after a typical start sequence with
four target devices added (one additional device shows, which is the
command and control LUN of the SDG Router itself).
Router > loggerDumpCurrent 1
*** Dumping 9 (1010 through 1018) current records with level >= 0 ***
