Using AoE (ATA-over-Ethernet)

Ageoff
#This is primarily aimed at users of Coraid devices.
#
#CONSOLE ACCESS
#
#On Coraid devices, access is possible via the usual PC keyboard,
#mouse and video, or the serial port, or cec(8). Typically, invoking
#
#! cec /net/ether0
#
#or
#
#! cec '#l1/ether1'
#
#will produce a menu of Coraid devices by MAC address, and you choose
#one.
#
#You may have to (once only) first type this on your Coraid console:
#
#! cecon /net/ether0
#! cecon /net/ether1
#! cecon /net/ether2
#
#PROVISIONING LUNS
#
#Once connected to the console, you can partition the available disks
#into Logical Units (LUNs). We'll assume a shelf number of 1 in these
#examples. If yours is different, use it in place of `1'.
#
#First declare some drives to be used as hot spares:
#
#! spare 1.13-14
#
#To create a big RAID 5 LUN, you would type something like this:
#
#! make 0 raid5 1.0-1.10
#! online 0
#
#which will create LUN 1.0 from drives 0 through 10 of shelf 1. This
#may take hours to finish, but you can use the LUN immediately.
#
#For single-drive LUNs, you would type something like this:
#
#! make 1 raidl 1.11
#! online 1
#
#which creates an un-RAIDed LUN of drive 11 of shelf 1.
#
#CLIENT CONFIGURATION
#
#The stock kernels all include devaoe and sdaoe, so you shouldn't
#need to build a new kernel.
#
#Adding these lines to your plan9.ini or /cfg/pxe file should cause
#AoE to be enabled automagically at boot time, per sdaoe(3):
#
#! aoeif=ether0
#! aoedev=e!#æ/aoe/1.0
#
#This assumes that your Plan 9 system has a single Ethernet
#interface. If you have several, choose the one that your AoE device
#is on. `1' is the shelf number of the AoE device. `1.0' is the
#logical unit you're interested in. `æ' is Unicode 00e6. `e' is the
#controller letter you'd like to use for logical unit 1.0.
#
#After your next boot, you should see a lightly populated /dev/sde0.
#Running `diskparts' should make any partitions visible.
#
#An AoE LUN appears to be a single large disk, often too large for
#the usual Microsoft partition table to address because it would
#require sector numbers greater than 2^32, so we skip the Microsoft
#partition table (the one maintained with disk/fdisk) and just lay
#down a Plan 9 partition table with
#
#! disk/prep /dev/sde0/data
#
