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