Figure 5-2: Troubleshooting Procedure When a Path Error Occurs
The following shows the procedure for using the HDLM command (
dlnkmgr
) to
handle a path error.
5.3.1 Examining the Messages
Examine the message that is output to syslog in the host by using applications or tools
for monitoring messages. If the KAPL08022-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 5.2 Checking Error Information in Messages.
5.3.2 Obtain Path Information
Obtain path information to narrow down the hardware in which an error has occurred.
Execute the following command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path -iem
-hbaportwwn > pathinfo.txt
pathinfo.txt
is the redirection-output file name. Use a file name that matches your
environment.
