41# DESCRIPTION:
42# ZFS volume as dump device, it should always have 128k volblocksize
43#
44# STRATEGY:
45# 1. Create a ZFS volume
46# 2. Use dumpadm set the volume as dump device
47# 3. Verify the volume's volblocksize=128k
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2008-12-01)
