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
