.TH aoe-mkshelf 8
.SH NAME
aoe-mkshelf \- create special device files for one shelf address
.SH SYNOPSIS
.nf
.B aoe-mkshelf {device-dir} {shelf-address}
.B env n_partitions=1 aoe-mkshelf {device-dir} {shelf-address}
.fi
.SH DESCRIPTION
The
.I aoe-mkshelf
command uses mknod to create the block special files necessary to
access the AoE devices with the given shelf address.
.PP
If your aoe driver supports only one partition per device (whole-disk
partitions), then the device files must match, and you should use the 
.I n_partitions
environment variable described below.
.SS Arguments
.TP
\fBdevice-dir\fP
This should be the name of the directory where the block device files
will be created.
.TP
\fBshelf-address\fP
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 \fBdevice-dir\fP.
.SH ENVIRONMENT VARIABLES
If the
.I n_partitions
variable is set in the environment, it will override the default
number of partitions per aoe disk, namely 16.
.SH EXAMPLE
In this example, the root user on a host named
.I 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 \fIn_partitions\fP set to 1.
