+# DESCRIPTION:
+#	Once a pool has been exported, and one or more devices are
+#	damaged or missing (d/m), 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 those are 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. Remove one or more devices
+#	5. Verify 'zpool import' will handle d/m device successfully.
+#	   Using the various combinations.
+#		- Regular import
+#		- Alternate Root Specified
+#	   It should be succeed with single d/m device upon 'raidz' & 'mirror',
+#	   but failed against 'regular' or more d/m devices.
+#	6. If import succeed, verify following is true:
+#		- The pool shows up under 'zpool list'.
+#		- The pool's health should be DEGRADED.
+#		- It contains the correct test file
+#
