Record priority
The priority of records in one tiering policy group is as follows.
• If you specified the same SMS storage group name, device number, or volume serial number for
multiple records, the record specified last is valid.
• If you specified the same volume with both the record for the device number and the record for
the volume serial number, the record specified last is valid.
• If one record specifies a volume, and another record specifies an SMS storage group that contains
the same volume, the volume specification in the former record takes priority.
