6 aoe-mkdevs - create special device files for aoe driver
7
9 aoe-mkdevs {device-dir}
10 env n_partitions=1 aoe-mkdevs {device-dir}
11
13 The aoe-mkdevs command is deprecated in favor of udev. Systems with
14 udev do not need to use the aoe-mkdevs or aoe-mkself commands, because
15 udev will create device nodes as needed.
16
17 Systems without udev use aoe-mkdevs to create the character special
18 files necessary to control the aoe driver. The aoe-mkdevs command uses
19 aoe-mkshelf to also create block special files.
20
21 The aoe drivers after version 49 support dynamic minor device numbers
22 so that a greater number of devices can be supported. The aoe-mkdevs
23 command is incompatible with dynamic device numbers. If your system
24 lacks udev, and you are using an aoe driver version 50 or above, use
25 the aoe_dyndevs=0 module option to force the aoe driver to use static
26 device numbers.
27
28 If you are not using dynamic device numbers, and you built your aoe
29 driver to support only one partition per device (whole-disk parti‐
30 tions), then the device files must match, and you should use the n_par‐
31 titions environment variable described below.
32
33 Arguments
34 device-dir
35 This should be the name of the directory where the special
36 device files will be created.
37
39 If the n_partitions variable is set in the environment, it will over‐
40 ride the default number of partitions per aoe disk, namely 16.
41
43 In this example, the root user on a host named nai creates special
44 files for using the aoe disks in shelf 7. After remembering that the
45 driver doesn't have partition support, this sysadmin gets rid of the
46 mismatching device nodes and calls aoe-mkdevs again with n_partitions
47 set to 1.
