NAME

       aoe-mkdevs - create special device files for aoe driver

SYNOPSIS

       aoe-mkdevs {device-dir}
       env n_partitions=1 aoe-mkdevs {device-dir}

DESCRIPTION

       The  aoe-mkdevs  command  is deprecated in favor of udev.  Systems with
       udev do not need to use the aoe-mkdevs or aoe-mkself commands,  because
       udev will create device nodes as needed.

       Systems  without  udev  use  aoe-mkdevs to create the character special
       files necessary to control the aoe driver.  The aoe-mkdevs command uses
       aoe-mkshelf to also create block special files.

       The  aoe  drivers after version 49 support dynamic minor device numbers
       so that a greater number of devices can be supported.   The  aoe-mkdevs
       command  is  incompatible  with dynamic device numbers.  If your system
       lacks udev, and you are using an aoe driver version 50  or  above,  use
       the  aoe_dyndevs=0  module option to force the aoe driver to use static
       device numbers.

       If you are not using dynamic device numbers, and  you  built  your  aoe
       driver   to   support   only   one  partition  per  device  (whole-disk
       partitions), then the device files must match, and you should  use  the
       n_partitions environment variable described below.

   Arguments
       device-dir
              This  should  be  the  name  of  the directory where the special
              device files will be created.

ENVIRONMENT VARIABLES

       If the n_partitions  variable  is  set  in  the  environment,  it  will
       override the default number of partitions per aoe disk, namely 16.

EXAMPLE

       In  this  example,  the  root  user on a host named nai creates special
       files for using the aoe disks in shelf 7.  After remembering  that  the
       driver  doesn't  have  partition support, this sysadmin gets rid of the
       mismatching device nodes and calls aoe-mkdevs again  with  n_partitions
       set to 1.

              nai:~# rm -rf /dev/etherd
              nai:~# aoe-mkdevs /dev/etherd
              nai:~# ls /dev/etherd | wc -l
              1603
              nai:~# rm -rf /dev/etherd
              nai:~# n_partitions=1 aoe-mkdevs /dev/etherd
              nai:~# ls /dev/etherd | wc -l
              103
