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 management-target 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 occurs. For details on each item

displayed in the message, 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:

# /usr/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.
