As I understand this explanation, system reset is a definitive manual
action that guarantees the 'down-ness' of a system. Like the hunter
'making sure' his buddy is really dead. But a total lack of vital signs,
like the TV-familiar solid hum of the life monitor, serves the same
purpose. Plus the red icons on the HMC.
We've been running sysplexes--parallel, basic, and mono--for 10 years.
Without a standard practice of system reset, have we just been lucky?
What do you do to shutdown? The red icons indicate that the LPAR is not
running, meaning that it is in STOP state or some sort of error state,
so you must have done something.
System reset is generally a good thing on a shutdown system. Among
other things, it does a "selective reset" to every I/O device, which
releases any RESERVES or pending conditions, resets path group
definitions, and generally clears the device.
