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 messages that are output to the host event log. 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.
If errors have occurred on all the paths to an LU, the KAPL08022-E message will
appear, in addition to the KAPL08026-E message.
When using the LU dynamic deletion function, the KAPL05301-E message will
appear if all the paths are deleted.
5.3.2 Obtaining Path Information
Obtain path information to narrow down the hardware in which an error has occurred.
Execute the following command:
>dlnkmgr view -path -iem -hbaportwwn > pathinfo.txt
