.B addaoe
.I letter
.I unit
.SH DESCRIPTION
.I Sdaoe
has a few quirks because
network-attached storage can't be enumerated as directly-attached storage can.
The default first controller letter for AoE devices is
.LR e .
Each
.B sdaoe
device must be configured explicitly.
.PP
.I Addaoe
packages up the
.L "switch on"
invocation as an
.I rc
script.
.PP
To boot from an AoE root, the
.B sd
device must be configured on boot by either PXE booting or
booting from directly-attached storage and adding two configuration lines to
.IR plan9.ini (8)
for
.BR aoeif ,
listing the names of the Ethernet interface(s) to use,
and
.BI aoedev= letter !#æ/aoe/ lun.
.SH EXAMPLES
To configure target (LUN)
.B 42.0
on
.BR #S/sde0 ,
.IP
.EX
echo config switch on spec e type aoe//dev/aoe/42.0 >/dev/sdctl
.EE
.PP
To turn this device off,
.IP
.EX
echo config switch off spec e >/dev/sdctl
.EE
.PP
To boot using target
.B 42.0
as
.B #S/sde0
and as root,
over Ethernet interfaces 0 and 1,
.IP
.EX
aoeif=ether0 ether1
aoedev=e!42.0

.SH BUGS
It is not currently possible to boot from an AoE target without an
external bootstrap like PXE.
