#
# ID: zpool_expand_003_neg
#
# Description:
# Once set zpool autoexpand=off, zpool can *NOT* autoexpand by 
# Dynamic LUN Expansion
# 
#
# STRATEGY:
# 1) Create a pool
# 2) Create volumes on top of the pool
# 3) Create pool by using the zvols and set autoexpand=off
# 4) Expand the vol size by zfs set volsize
# 5) Check that the pool size is not changed
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-06-12)
#
