# ID: zpool_import_missing_005_pos
#
# DESCRIPTION:
#	Verify that a pool can still be imported even if its devices' names
#	have changed, for all types of devices.  This is a test of vdev_geom's
#	import_by_guid functionality.
# STRATEGY:
#	1. Create a supply of file-backed md devices
#	2. Create a disk-backed pool with regular, cache, log, and spare vdevs
#	3. Export it
#	4. Cause all the md devices names to change
#	5. Verify 'zpool import' can import it
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2015-01-4)
