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 using target
42.0
as
#S/sde0
and as root,
over Ethernet interfaces 0 and 1,
aoeif=ether0 ether1
aoedev=e!42.0

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