We recently had a customer with a power outage and the HMC and AS400 went down hard.  When the power was restored the AS400 was ready to come up, but the HMC had a hard drive crash. If your HMC is set up right you can just push the button on the AS400 and it should start up.  But this time it wouldn’t power on, the reason was the HMC “Power-On Parameter” policy was set to, User-Initiated.  This needs to be set to Auto Start – Always for this option to be available to you.
