3. Set the parameters that you want.

Parameter	Description
overall %	Specifies the drivewise % or common % as set for
	each drive. If Drivewise is selected, the drive
	parameters are specified for each drive used. If
	Common is selected, all drive parameters use the %
	parameters, which are entered in the % for Common
	fields. This reduces the need to set each drive
	parameter if the server has a large number of drives.
Common:	Use the term % to specify all drives
SCSI Disk n	Specify an individual drive parameter.
