.TH aoe-stat 8
.SH NAME
aoe-stat \- print aoe device status report
.SH SYNOPSIS
.nf
.B modprobe aoe
.B aoe-stat
.B env sysfs_dir=/sys aoe-stat
.fi
.SH DESCRIPTION
The
.I aoe-stat
script collects information on ATA over Ethernet devices from sysfs.
.PP
For each AoE device the kernel has discovered, there is one row in the
script's output. Each row has
the following columns.
.TP
.BI devicename
The device name is of the form
.I eX.Y,
with
.I X
being the AoE device shelf address, and
.I Y
being the AoE slot address.
.TP
.BI size
The size of the AoE device is in gigabytes (billions of bytes).
.TP
.BI ifname
The network interface name is printed in the third column.
.TP
.BI status
The device status is in the last column. Possible values
are \fI up\fR, \fI down\fR,
and \fI down,closewait\fR. The "up" status means the aoe driver
considers this device ready
for I/O. The "down" status means the opposite. The "down,closewait"
status means that some software still has the device open, and when
this straggler closes the device, it will enter the "down" state.
.SH ENVIRONMENT VARIABLES
If the
.I sysfs_dir
variable is set in the environment, it will override the default
location where
.I aoe-stat
will look for
sysfs, namely \fI /sys\fR.
.SH EXAMPLE
In this example, the root user on a host named
.I nai
loads the aoe driver module and then prints a list of all the
available aoe devices. Then he remembers to bring up the storage
network interfaces, does an AoE discovery, and prints the list again.
This time the list shows all the devices in shelf seven.
