CMMVC9402E The SCSI LUN ID currently allocated to the volume mapping is not available in all of the new access IO groups.

Explanation
This error can occur when a SCSI LUN ID is not available in all of the access I/O groups that are
being added. The specified volume mapping has a SCSI LUN ID that is allocated to it in the access
I/O groups in the current access I/O group set. The SCSI LUN ID is the same for all access I/O
groups in the access I/O group set, but is not available in all of the new access I/O groups that
are being added.

User response
Remove the host mapping in the new access I/O groups that is using the required SCSI LUN ID and
then retry the command. Alternately, if the host supports mismatched SCSI LUN IDs, use the
-allowmismatchedscsiids option to assign a different SCSI LUN ID to the
volume.
