5.3.2 Using the dlnkmgr Command to Handle a Path Error
The following subsections show the procedure for using the HDLM command (dlnkmgr) to
handle a path error.
5.3.2.1 Examine the Messages
Examine the message that is output to the event log in the host 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 section
5.2.
If an error occurred in all the paths to the LU, the KAPL08022-E message appears, in addition
to the KAPL08026-E message.
When using the LU dynamic deletion functionality, the KAPL05301-E message appears if all
paths are deleted.
5.3.2.2 Obtain Path Information
Obtain path information to narrow down the hardware in which the error occurred. Execute
the following command:
>dlnkmgr view -path -iem > pathinfo.txt
The redirection-output file name is pathinfo.txt. Use a file name that matches your
environment.
5.3.2.3 Identify the Error Path
Check the obtained path information to find the error path. In the Status column, the
error path has the status Offline(E) or Online(E).
5.3.2.4 Narrow Down Hardware Causes
Check the DskName, iLU, and ChaPort columns for the error path to narrow down the
hardware that may be the cause of the error. To physically identify the hardware
corresponding to DskName, iLU, and ChaPort, use the information provided by the
storage-system management program.
