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.
