ATA over Ethernet driver 64 (For Linux 2.6 branch)
This driver allows the Linux kernel to use the ATA over Ethernet (AoE) network protocol. Using AoE, a Linux system can use AoE block devices like EtherDrive (R) storage blades. The block devices appear as local device nodes (e.g. /dev/etherd/e0.0). License: GNU General Public License (GPL) Changes:
The compatibility system was generalized. Support for the 2.6.26 Linux kernel was added.Image

aoe-mkshelf(8)						      System Manager's Manual						    aoe-mkshelf(8)

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:~#
