# DESCRIPTION:
#	Verify import behavior for inactive, but not exported, pools
#
# STRATEGY:
#	1. Create a zpool
#	2. Verify multihost=off and hostids match (no activity check)
#	3. Verify multihost=off and hostids differ (no activity check)
#	4. Verify multihost=off and hostid allowed (no activity check)
#	5. Verify multihost=on and hostids match (no activity check)
#	6. Verify multihost=on and hostids differ (activity check)
#	7. Verify mmp_write and mmp_fail are set correctly
#	8. Verify multihost=on and hostid zero fails (no activity check)
#	9. Verify activity check duration based on mmp_write and mmp_fail
