Correcting a path-related configuration error

Complete this task to correct a path-related configuration error with DS CLI commands.

There might be occasions when you are using the mkpprcpath command to establish a path between the specified source and target LSSs and the transaction fails. You might not be aware of the failure until you run the lspprcpath command to check the status of the paths that have been established between the specified source and target LSSs.

The lspprcpath command displays a report that includes a state category. The state category reports on the current remote mirror and copy path state. One of the state codes is configuration error. A state code of configuration error is an indication that you have specified an incorrect value for the remote WWNN or the target lss ID.

Perform the following steps to correct the configuration error with DS CLI commands.

Check the original input values you provided for the -remotewwnn and -tgtlss parameters.
The following criteria applies to these parameters:

-remotewwnn

You must use the worldwide node name that is associated with the secondary storage unit. If you use the WWNN (worldwide node name) that is associated with the primary storage unit, the mkpprcpath command fails. Issue the lssi or showsi command to obtain the remote WWNN number of the secondary storage unit.

tgtlss

You must use the logical subsystem ID that is associated with the secondary storage unit as the target. You can verify that you have used the correct value by looking at the report that is generated by the lspprcpath command.
Obtain the correct values for the remote WWNN or target LSS ID and reissue the mkpprcpath command followed by issuing the lspprcpath command to verify that your transaction has processed correctly.
