# ID: zvol_swap_003_pos
#
# DESCRIPTION:
# Verify that a zvol device can be used as a swap device
# through /etc/vfstab configuration.
#
# STRATEGY:
# 1. Create a pool
# 2. Create a zvol volume
# 3. Save current swaps info and delete current swaps
# 4. Modify /etc/vfstab to add entry for zvol as swap device
# 5. Use /sbin/swapadd to zvol as swap device throuth /etc/vfstab
# 6. Create a file under $TMPDIR
# 7. Verify the file
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
#
