Driver Compatibility

Users of udev have device nodes like /dev/etherd/e0.0 created for them
automatically, as needed. These are dynamic device nodes.

Some systems use static device nodes, which are present in /dev
regardless of what devices are really available to the system. The
aoetools contain the aoe-mkdevs and aoe-mkshelf commands, which create
static device nodes.

To guard against confusion, it's important to have an aoetools
installation that is compatible with your aoe driver. If you use an
aoe driver from the Coraid website
(http://www.coraid.com/support/linux/) then just use the aoetools that
come bundled with that deiver. If you didn't get your aoe driver from
the Coraid website, then here's what to do:

    * Of course, read the README file in the aoetools sources.

    * To use aoetools-8 and later with older 2.6 kernels (2.6.13 and
      earlier), build the aoetools with an extra parameter for "make",
      like this:

        make NPERSHELF=10

    * To use aoetools-5 through aoetools-7 with newer 2.6 kernels
      (2.6.14 and later), build the aoetools with an extra parameter
      for "make", like this:

        make NPERSHELF=16

    * Using aoetools-4 and earlier with newer 2.6 kernels (2.6.14 and
      later) is not recommended.

Other combinations should work with the default settings.
