If the only thing you want is to power on, your machinery, and nothing |
| 17 |
more(such as load a kernel via network, or create diskless nodes with a shared nfs |
| 18 |
root), then checkout two possibilities. The first one is to see if you |
| 19 |
have any hardware controller such as "hewllet packard's iLO(Integrated |
| 20 |
Lights-Out), or intel's ipmi (Intelligent Platform Management Interface) |
| 21 |
in your machines. If you 've got an IPMI device you will be able to |
| 22 |
use eg. ipmitool from another machine, to start your cluster, power off |
| 23 |
your cluster, and do some more management, eg. seeing temperatures and |
| 24 |
speed of fans. If you owe an HP proliant server with iLO, you will be |
| 25 |
able to telnet or ssh inside the software interface iLO provides(every |
| 26 |
controller takes an IP), and do |
| 27 |
some work, such as power on/off your machines again. iLO offers a web |
| 28 |
interface too, but I hate that, cause you have to pay to load another |
| 29 |
firmware to be able to do more.. For ipmi do a search in portage to see |
| 30 |
the tools available by gentoo (emerge --search ipmi). |
| 31 |
|
| 32 |
If your hardware is |
| 33 |
not so valuable to have such controllers, then hopefully you will be |
| 34 |
able to send a "wake on lan" magic packet, to power on you machines. |
| 35 |
(see in portage, net-misc/wakeonlan and net-misc/wol for such tools, |
| 36 |
and read http://en.wikipedia.org/wiki/Wake-on-LAN). |
| 37 |
|
| 38 |
If you want something more than that, start by reading something like |
| 39 |
http://www.gentoo.org/doc/en/diskless-howto.xml |
| 40 |
It's about how to create diskless nodes with gentoo, and it's not what |
| 41 |
you want I suppose, but it has some doc about PXElinux and etherboot, |
| 42 |
and how to create a shiny dhcp server for this stuff(+more). |
