Use the DEV parameter to select records from one or two of the device types instead of all three.

Use the DEVSER or VOLID parameter to select records according to the device serial number or volume serial number.

The DEVSER selection parameter only applies to the threshold summary. The DEVSER parameter is only valid with TYPE=O, because only tape OBR records contain device serial numbers.
