ADIC FileServ Version 4.0 600716 Rev A manual Spanning

AdministrativeTasks

When hard-linked files are stored and retrieved, the common file data is stored or retrieved for all of the links, no matter which file name is submitted with the fsstore command.

The return status for the operation lists a file name of any one of the links and not necessarily the file name submitted as an argument with the command. If a different linked file name is returned in the status, the file data was correctly handled.

FileServ prevents hard links between files across DataClass boundaries.

Symbolic links can cross DataClass boundaries and file system boundaries.

Tip

ADIC does not recommend you use symbolic links across

DataClass groups.

	The DataClass parameters that control the original file are the
	DataClass groups of the file links, regardless of the location.
	Soft links that cross DataClass groups are misleading, because
	the file data can actually reside in a different class.
Spanning	FileServ supports file spanning across media. If a file is larger
	than a single piece if media, the file will span to another piece
	of media until the entire file is stored.
	A file that spans multiple media always starts at the beginning
	of each additional media required to store the file. The file is
	stored on media until all available space is used, the remaining
	part of the file (spanned portion) is stored on a blank media. If
	the file overflows another media, another blank is used until the
	entire file is stored.
