Information Collected by the DLMgetras Utility for
Collecting HDLM Error Information
Immediately after an error occurs, execute the DLMgetras utility for collecting
HDLM error information, since restarting the machine might delete error
information before the information is collected by DLMgetras. For details
about the DLMgetras utility and the error information it collects, see
DLMgetras Utility for Collecting HDLM Error Information on page 7-4 .
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 view (Displays Information) on page 6-32 .
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 = aa...aa,PathID =
bb...bb,PathName = cc...cc.dd...dd.ee...ee.ff...ff,DNum =
gg...gg,HDevName = hh...hh
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
view (Displays Information) on page
6-32 .
