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
