ADIC FileServ Version 4.0 600716 Rev A manual Overflow Policy

		AdministrativeTasks
Overflow Policy	The HIBLK_THRESHOLD and LOBLK_THRESHOLD system
	variables are located in the fs_sysparm file. These variables
	are system-wide parameters.
	FileServ reads the new values at startup time. If FileServ is
	running, you must recycle the system to pickup the new values.
	If the overflow hiblk value is reached for a file system, the
	$FS_HOME/internal/policy_dir/fs_spt_ovflow
	script is automatically invoked. This script is used for:
	• Emergency situations when routine data cleanup is not
	maintained for a file system,
	• Or, when data is rapidly stored to the disk before the routine
	storage policy reacts.
		Note
		SGI ONLY: If HIBLK_THRESHOLD and
		LOBLK_THRESHOLD parameters are not given to a file
		system, the emergency script is never invoked for that file
		system, regardless of the disk usage.
	• Using the fspolicy Command
	The fspolicy command is run to store eligible files from disk
	to media or to truncate files on disk that are fully stored to
	media
	Note
	For more information on the fspolicy command, refer to the
	Command Reference book.
