NAME

sdaoe − 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
/dev/sdl0/ctl
/dev/sdl0/raw
/dev/sdl0/data
...

­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 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.
