+# Zpool Raid-0 Configuration
+#
+# This script is used to simplify testing with the /dev/disk/zpool/[A-Z][1-n]
+# devices.  It assumes that you have already populated /dev/disk/zpool/ by
+# creating an /etc/zfs/zdev.conf file based on your system design.  You may
+# use the zpool_layout command or manually create your own config file.
+#
+# You can then use either the zpool-create.sh or the zpios.sh test script to
+# test various Raid-0 configurations by adjusting the following tunables.
+# For example if you wanted to create and test a single 4-disk Raid-0
+# configuration using disks [A-D]1 with dedicated ZIL and L2ARC devices
+# you could run the following.
+#
+# ZIL="log A2" L2ARC="cache B2" RANKS=1 CHANNELS=4 \
+# zpool-create.sh -c zpool-raid0
+#
+# zpool status tank
+#   pool: tank
+#  state: ONLINE
+#  scan: none requested
