Controlled start up

I'm sure there is an answer to this, I just can't find it!!!
I current have a small network of 10 servers one of which, the PDC, is plugged into my APC UPS via a USB lead. when the PDC detects that it has been on battery power for two minutes it runs a script to cleanly shut down all the other servers, before shutting its self down.

However, once the UPS detects that mains power is available all the servers come up together, is there a way I can control the order in which the servers are brought back up. ideally I'd like PDC and BDC to come up first before anything else as this seems to make my life easier when it does.

Yes, you can do it with Wake-on-Lan feature, if motherboards of your servers support it (they should).
Just download free wolcmd proggy, put it somewhere on your PDC, and create some batch file, which will run at PDC startup.
Ok, it will also run each time you restart PDC, but if other machines are already up and running, there is no damage.

Take a look here for free WOLCMD download and script examples:

Thanks for the heads up on the Wolcmd. However, I have already tired it and yes it does bring the remaining servers up. I was just wondering if there was a way of stopping the servers firing up when they detect mains power so I could use my wolcmd script.

To prevent servers to automatically power up when mains power is on, you simply change BIOS settings, where you can select the power-on state after power recovery:
- previous state
- off (this is your choice)
- on

Then you can use wake-on-lan script to launch other servers manually after PDC is up.
