Bootup of IBM pSeries systems.
Funny discussion about boot-up times of pSeries systems:
Hey, I manage 7 p595 squadrons and they are all different. For the most part, the startup time depends on the amount of I/O you have installed. Two of mine are 3 frame p595's with 64 hba, 64 nic, about 20 internal HDD, dual power systems and I think 10 d20 I/O drawers. These servers take about 90 minutes just to initialise the hardware, not including starting any LPAR's. So tell your friend that this is normal and take a good book and a really large coffee with him each time he needs a restart
