# DESCRIPTION:
# ZFS volume as dump device, it should always have 128k volblocksize
#
# STRATEGY:
# 1. Create a ZFS volume
# 2. Use dumpadm set the volume as dump device
# 3. Verify the volume's volblocksize=128k
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2008-12-01)
