NAME

       aoe-mkshelf - create special device files for one shelf address

SYNOPSIS

       aoe-mkshelf {device-dir} {shelf-address}
       env n_partitions=1 aoe-mkshelf {device-dir} {shelf-address}

DESCRIPTION

       The  aoe-mkshelf  command  is  not  needed  on  systems  that have udev
       installed  and  is  incompatible  with  aoe  drivers  that   have   the
       aoe_dyndevs module parameter set to 1.

       Systems  lacking  udev  and having an aoe driver that uses static minor
       device numbers can use aoe-mkshelf to create the  block  special  files
       necessary to access the AoE devices with the given shelf address.

       All  aoe  drivers  prior  to  aoe6-50  use static minor device numbers.
       Versions 50 and up use dynamic minor device  numbers  when  the  module
       parameter aoe_dyndevs=1 is set.

       If  you  are  using  static  minor  device  numbers and your aoe driver
       supports 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 block  device
              files will be created.

       shelf-address
              This  is  the  AoE major address, or shelf address, for which to
              create device nodes.  For example, specifying a shelf address of
              1  means  that  the e1.* device nodes will be created in device-
              dir.

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.  Then he remembers  that  the
       driver  doesn’t  have partition support, so the command is called again
       with n_partitions set to 1.

              nai:~# aoe-mkshelf /dev/etherd 7
              nai:~# ls /dev/etherd/e7.* | wc -l
              160
              nai:~# rm /dev/etherd/e7.*
              nai:~# n_partitions=1 aoe-mkshelf /dev/etherd 7
              nai:~# ls /dev/etherd/e7.* | wc -l
              10
              nai:~#
