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:~#
