ADIC FileServ Version 4.0 600716 Rev A Time parameters does not establish the DataClass migration

AdministrativeTasks

Minimum Time Parameters

The mintime is the minimum amount of time after the file is written or read before any policy action is taken. The mintime determines eligibility for file storage and for file removal from disk. For the cleanup policy, mintime is calculated as the time elapsed after a file was stored on media before being removed from disk.

Setting both the File Cleanup Action and Minimum Time parameters tend to keep available disk space high by freeing disk blocks as soon as possible (the immediate setting). These parameters keep active files available on disk as long as possible, thus freeing disk space as files become inactive.

Note

In this case, active means frequently accessed.

	However, setting the File Cleanup Action and Minimum
	Time parameters does not establish the DataClass migration
	behavior of the files.
	Rather, the planned execution of migration and disk cleanup
	policies as well as the DataClass characteristics provide the
	overall migration behavior for DataClass groups.
Policies	Migration management includes the application of storage and
	cleanup policies using the fspolicy command with various
	options. Changing the overflow parameters in the fstab file
	also affects migration.
