Task 4: Restore the Data

	To restore the data:
	1. Perform a disaster recovery on the shared disk using mmrecov and
	recover. For more information about performing a disaster recovery, refer
	to the Legato NetWorker Administrator’s Guide, UNIX Version.
	When you shut down the NetWorker software during this step, use
	cmhaltpkg and not nsr_shutdown, as follows:
	# cmhaltpkg networker
	# exchange -a c /dev/vg03
	# mount /dev/vg03/lvol1 /vg031
	# mv /vg031/nsr/res /vg031/nsr/res.old
10	# mv /vg031/nsr/res.R /vg031/nsr/res
	# umount /vg031

# vgchange -a n /dev/vg03

# cmmodpkg -e networker (to restart the NetWorker software)

2. Recover the clients' data from recent backups.
