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).
