Appendix C

Diagnostic Messages

The HP-UX iSCSI Software Initiator works with HP-UX Event Monitoring Services (EMS) and the Support

Tools Manager (STM). By default, the iSCSI Software Initiator logs all diagnostic messages to the STM log

files. STM can be used to view the diagnostic messages logged in the STM log files.

EMS can be configured to automatically notify the system administrator when diagnostic messages are

logged by the iSCSI Software Initiator.

In addition to logging all diagnostic messages to the STM log files, the iSCSI Software Initiator logs some of

the diagnostic messages to the /var/adm/syslog/syslog.log file.

The messages that can be logged to the syslog.log file are defined at 8 levels. By default, messages with

numerical values less than or equal to LVL_ERR (Level 3) will be logged. See Table C-1, “Logging Levels for

the syslog.log File,” below, for detailed descriptions of logging levels.

Logging Level Level

Number

Description

LVL_PANIC 0 The system is unusable and a panic will follow. The message will

provide additional data about the panic.

LVL_ALERT 1 The system has entered a state that requires an action by the

administrator. The message describes the condition, and the action

that must be taken

LVL_CRIT 2 A critical event has occurred. The system is still usable. The message

will provide additional details about the event.

LVL_ERR 3 An error condition has occurred. The system is still usable. The

message will provide additional details about the error.

LVL_WARN 4 An event has occurred that may indicate some future action is

necessary. The system is still usable, and the current system

operation has not been affected. The message will provide additional

details about the warning.

LVL_NOTE 5 An event has occurred that fits the normal profile of operation,

however, the event is called out so that it may be viewed in the context

of other things occurring in the system. The system is still usable, and

the current system operation has not been affected. The message will

provide additional details about the noted event.

LVL_INFO 6 An informational message regarding some unusual, but acceptable,

event that occurred during system operation. The system is usable,

and the information can be ignored. The message will provide

additional details.

LVL_DEBUG 7 A debug message used internally by the HP lab to assist in debugging

an exception event. Customers should not attempt to interpret

messages at this level.
