I have a bladecentre with blades, network and a SAN in a single rack.

What I'd like to do is control the startup of the bladecentre so that when the rack is powered on that the blades will delay their bootup until the SAN is powered on correctly.

Is this even possible? We have an AMM in the chassis if that helps. Basically we are looking into the reboot that occurs after power is restored to a UPS.

I sincerely apologise for the noobness of this question, but I am a software guy trying to help :)
