Side aware configuration examples
This appendix shows an example of a side aware configuration for a log, data, and shared file system.
An example configuration for a log file system is shown in Example E-1.

An example configuration for shared is shown in Example E-3.

The commands that are used for creating file systems (after mmcrvdisk -F filename, mmcrnsd -F filename) are shown in Example E-4.
