+This script supports the following parameters for Windows & Linux platforms:
+  -d <deviceNames>,    REQUIRED, Space separated list of devices to mount /data on,
+                       i.e., "xvdb xvdc", more than one device indicates a RAID set.
+                       For Windows, specify the drive letter, i.e., "d".
+  -r <raidDeviceName>, REQUIRED, if more the one device is specified in <deviceNames>,
+                       i.e., md0.
+                       Not supported on Windows.
+  -l <deviceName>,     OPTIONAL, Device name to mount /log on, i.e., "xvdd".
+                       For Windows, specify the drive letter, i.e., "e".
+  -t <fsType>,         File system type, defaults to '$fs_type'.
+                       Not supported on Windows.
+  -o <mountOptions>,   File system mount options, i.e., "-m crc=0,finobt=0".
+                       Not supported on Windows.
+  -u <user:group>,     User:Group to make owner of /data & /log. Defaults to '$user_group'.
