You have already seen many references to dcli and cellcli in the previous chapters. Although the syntax appears quite intuitive, a more thorough discussion of what you can do with the tools is certainly in order. You probably ended up here following a reference in another chapter. This appendix is not meant to be a comprehensive discussion of what you can do with the tools. You have the Exadata Storage Server Software User’s Guide Chapter 8 (Using the CellCLI Utility) and Chapter 9 (Using the dcli Utility) for this. The appendix is rather your guide to getting started and understanding two of the most useful configuration tools available for the Exadata system. The cellcli part is a bit longer, paying tribute to the more powerful of the two utilities.
