Administrative Tasks

	If problems are discovered, correct them before
	continuing.
Step 6.	Mount a tape on a drive.
Step 7.	Run the fsdump command with the arguments
	appropriate to the platform as specified in the man
	page. Enter the destination file or drive and any
	optional arguments if appropriate.

	% fsdump -f /dev/rmt/tps0d3 /arch

	The fsdump utility prompts the user to change tapes
	if more than one tape is required. A sequence number
	is given each tape, starting at 1.
	• Change tapes when prompted.
	• Label tapes with the sequence number so they

	can be restored in the proper sequence.
Restore Data	File systems that are checkpointed with the fsdump command
	are restored with the fsxrestore command.

	Note

	Restored files and directories have the same permissions as
	when they were dumped.

	If new relation points have been added, run fsdump so these
	directories are located on the dump tape. The fsaudit
	command fails if all parents of relation points are not on the
	dump tape.
	The fs_dump.file is also restored to disk for use by the
	fsaudit -r command.
