applications or tools for monitoring messages. If the KAPL20023-E message
is output, view the message to check the path in which the error has
occurred. For details on each item displayed in messages, see

Execute the following command from the remote management client:
dlnkmgr -s host-name -u user-name -p password view -path -iem -
hbaportwwn > pathinfo.txt
pathinfo.txt is the redirection-output file name. Use a file name that
matches your environment.
