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.
