Logging Location Codes

Using Log Files

The key information in each log message is the log class and the

location code number, which uniquely identify the logging message for

that entity, and the Parm. You use these numbers to ﬁnd the

explanation and action in the tables in this section and other sections of

this manual. The actions given should be performed. Only if there is no

clear error reported or the recommended action fails should system

level troubleshooting be performed. When the system level tests are

done, it is advisable to use the conﬁguration ﬁles that have most of the

logging classes conﬁgured for the console. This saves having to format

the log ﬁles for the log messages received during the test.

Internal Errors

Each subsystem has a log class deﬁned for internal errors, as listed in

Table 21-1. If an internal error ever occurs, a log message is sent to the

console. Record the log message exactly and consult this manual for the

recommended action, which in most cases is to contact HP; refer to

Appendix A , “Submitting a CR,” of this manual.

Some error messages have an extra parameter whose explanation reads

“Parm = BFM result code.” The error codes that are produced by the

buffer manager are listed in Table C-1 and Table C-2. Those tables

contain all of the error codes returned by the NS 3000/iX native mode

and compatibility mode buffer manager interfaces.

Informative and Non-Critical Errors

The Network Transport logs all normal or informative events to

CLAS0005. Because of the high number generated, messages for this

class are not normally recorded, even to the disk log ﬁle. However, if

any of the normal events encounters an error condition, an additional

log message is generated that is recorded with the log ﬁle. This is

CLAS0003, non-critical error.

An example of log class 3, non-critical error, is shown in Figure 21-2.

This example shows a non-critical, or Class 3, log message for TCP. The

ﬁrst part describes the log message, including the event, the entity, the

internal event and the log class. In Figure 21-2, the internal event is

retransmission which indicates that there was an attempt to

retransmit a TCP packet. The parameter number indicates the

sequence number of the packet that was retransmitted. Also check the

explanation and action listed under the Location Code number which is

61 in the example. The TCP PM section describes the protocol module

Location Code.
