# DESCRIPTION:
# Attempt to access a dump device on a RAID-Z pool.
#
# STRATEGY:
# 1. Create a RAID-Z pool.
# 2. Create a zvol on that pool called "dump".
# 3. Configure it with "dumpadm".
# 4. Attempt to issue reads and writes to it.
#

# Save the current dump device so we can restore it after the test.
orig_dump_device=$(dumpadm | awk '/Dump device/ { print $3 }')
