# ID: zpool_import_all_001_pos
#
# DESCRIPTION:
# Verify that 'zpool import -a' succeeds as root.
#
# STRATEGY:
# 1. Create a group of pools with specified vdev.
# 2. Create zfs filesystems within the given pools.
# 3. Export the pools.
# 4. Verify that import command succeed.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
