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 parti- tions), 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 SEE ALSO

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:~# SEE ALSO
