Re: V5R4M0 upgrade - HMC as well?

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Aha true enough. But as with all LandMines this may happen when you 
don't expect it. If the designated service partition is the only one 
running and it does a PWRDWNSYS RESTART(*YES) you get a server IPL (or 
Deep IPL as IBM refers to i) as a free 'bonus'.  The MH PTFs get applied 
as fixes to the firmware, they are made active AND automatically 
accepted to the P side and then i5/OS comes back up 'after a time.'  If 
your HMC is too old to communicate with the new level of code in the FSP 
then it stays dark and you call IBM. :-)  Therein is the landmine - 
discovered when you were not looking for it.
