#
# ID: zfs_002_pos
#
# DESCRIPTION:
# With ZFS_ABORT set, all zfs commands should be able to abort and generate a core file.
#
# STRATEGY:
# 1. Create an array of zfs command
# 2. Execute each command in the array
# 3. Verify the command aborts and generate a core file 
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-06-29)
