# __stc_assertion_start
#
# ID: zpool_expand_001_pos
#
# DESCRIPTION:
# Once zpool set autoexpand=on poolname, zpool can autoexpand by 
# Dynamic LUN Expansion
# 
#
# STRATEGY:
# 1) Create a pool
# 2) Create volume on top of the pool
# 3) Create pool by using the zvols and set autoexpand=on
# 4) Expand the vol size by 'zfs set volsize'
# 5) Check that the pool size was expanded
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-06-12)
#
# __stc_assertion_end
