NAME
sdaoe, addaoe - ATA-over-Ethernet (AoE) storage device
interface
SYNOPSIS
bind -a #S /dev
echo config switch on spec l type aoe//dev/aoe/shelf.slot >/dev/sdctl
echo config switch off spec l >/dev/sdctl

addaoe letter unit
DESCRIPTION
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 `e'.
Each sdaoe device must be configured explicitly.
Addaoe packages up the `switch on' invocation as an rc
script.
To boot from an AoE root, the sd device must be configured
on boot by either PXE booting or booting from directly-
attached storage and adding two configuration lines to
plan9.ini(8) for aoeif, listing the names of the Ethernet
interface(s) to use, and aoedev=letter!#æ/aoe/lun.
EXAMPLES
To configure target (LUN) 42.0 on #S/sde0,
echo config switch on spec e type aoe//dev/aoe/42.0 >/dev/sdctl
To turn this device off,
echo config switch off spec e >/dev/sdctl
To boot from an AoE root, the sd device must be configured
on boot. To accomplish this, one must either PXE boot or
boot from direct-attached storage and add two configuration
lines to plan9.ini(8). For example, to boot using target
42.0 as #S/sde0 and as root, over Ethernet interfaces 0 and
1,
aoeif=ether0 ether1
aoedev=e!#æ/aoe/42.0

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