# ID: zpool_import_missing_002_pos
#
# DESCRIPTION:
# 	Once a pool has been exported, and one or more devices are 
#	move to other place, import should handle this kind of situation
#	as described:
#		- Regular, report error while any number of devices failing.
#		- Mirror could withstand (N-1) devices failing 
#		  before data integrity is compromised 
#		- Raidz could withstand one devices failing 
#		  before data integrity is compromised 
# 	Verify that is true.
#
# STRATEGY:
#	1. Create test pool upon device files using the various combinations.
#		- Regular pool
#		- Mirror
#		- Raidz
#	2. Create necessary filesystem and test files.
#	3. Export the test pool.
#	4. Move one or more device files to other directory 
#	5. Verify 'zpool import -d' with the new directory 
#	   will handle moved files successfullly.
#	   Using the various combinations.
#		- Regular import
#		- Alternate Root Specified
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-08-01)
