Examining The Messages; Obtaining Path Information - Hitachi XP P9500 User Manual

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.

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 Checking Error Information in Messages on page
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.

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
pathinfo.txt is the redirection-output file name. Use a file name that
matches your environment.
