5.2 Checking error information in messages

When you want to configure the system so that HDLM messages are output to syslog,

specify

user

for the name of the system function defined in the

/etc/syslog.conf

file. In the following example, the system function name is

user

, and messages at the

Information level or higher are output to the

/etc/syslog.conf

file:


user.info /tmp/syslog.user.log

You can check path errors by referring to the KAPL08xxx messages that are output to

syslog.
To obtain detailed information about the failed path, check the execution results of the

view

operation as indicated by the error message.

For details on this operation, see 6.7 view (Displays Information).
Based on the applicable message, detailed information about a path can be obtained by

checking the execution results of the

view

operation.

The following is an example of a message:

KAPL08022-E Error in path occurred. ErrorCode =

The elements of the message are explained below.

ErrorCode

The error number generated when AIX detected the path error.

PathID

The ID assigned to a path. This ID is called the

AutoPATH_ID

.

AutoPATH_IDs

are re-assigned every time the host is restarted or every time the path

configuration is changed. When you want to add a new LU without restarting the

host, AutoPATH_IDs are re-assigned to each path of the LU when you execute the

cfgmgr

command.

This path ID is the same as the path ID displayed by the

dlnkmgr

command's

view

operation.

For details on this operation, see 6.7 view (Displays Information).
