  21 # DESCRIPTION:
  22 #       Under no circumstances when multihost is active, should an active pool
  23 #       with one hostid be importable by a host with a different hostid.
  24 #
  25 # STRATEGY:
  26 #        1. Simulate an active pool on another host with ztest.
  27 #        2. Verify 'zpool import' reports an active pool.
  28 #        3. Verify 'zpool import [-f] $MMP_POOL' cannot import the pool.
  29 #        4. Kill ztest to make pool eligible for import.
  30 #        5. Verify 'zpool import' fails with the expected error message.
  31 #        6. Verify 'zpool import $MMP_POOL' fails with the expected message.
  32 #        7. Verify 'zpool import -f $MMP_POOL' can now import the pool.
  33 #        8. Verify pool may be exported/imported without -f argument.
