		ADIC recommends that migration policies be applied on a
		routine basis. Periodic application of migration policies is best
		accomplished through the use of a crontab, to invoke many
		routinely executed UNIX commands.

The following types of policy can be run:

•Store data to tape (based on DataClass parameters).

•Remove data from disk (based on disk space)

The fspolicy -scommand is used to invoke the policy to store data to tape. Eligibility for storage is based on the DataClass parameters of class.

% fspolicy -s -c class

The fspolicy -tcommand is used to invoke the policy to truncate data from disk after it has been stored to tape. Eligibility for truncation is per file system filesystem and based on the file attributes, such as last access date.

% fspolicy -t -y filesystem
