To run AMD, you simply type amd at the prompt, providing the mount point(s) amd the map(s) on the command line. For example, if the map in listing 1 is named /etc/map.main, and a map named /etc/map.silly also exists, to execute AMD you would type:
amd /u /etc/map.main /silly /etc/map.silly
It is a good idea to include this statement in your rc files.
A number of options are available for the amd command. Two useful options are the ability to specify the NFS mount points and the timeout period. The program amq helps control AMD. For example, amq can force AMD to unmount a file system and to flush the cache (useful when debugging NFS problems). The man page for amq provides a complete description of all its capabilities.
Because AMD is just a front end to regular NFS, you have to worry about the same issues that you would when running NFS alone—you must ensure that exports and their options are correct. Explaining NFS is beyond the scope of this article; however, if you are unfamiliar with the basics of NFS, see the NFS Resources box on page FIXME.
Binaries and patches to port AMD to Linux may be obtained from sunsite and other sources (see sidebar). AMD has stayed relatively stable and bug free in the last few years; development is no longer active. AMD comes with excellent documentation.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
