Once again my perspective. Store Status either will or will not 'save the
exact same data' depending on how you define 'same'. The process is more
(mostly? entirely?) a function of hardware. What you get is effectively the
register, PSW, etc. (too lazy to crack the book) data reflecting the state
of the control program that was last running in the LPAR at moment your
favorite operator Mashed Load. For an ordinary SAD, you almost certainly
want that data to represent the z/OS or VM or Linux (or TPF?) operating
system that failed beyond expectation of repair within a reasonable outage
window. So you almost always want exactly one and only Store Status for SAD
to capture.
In real life, many shops take advantage of HMC wizardry to define SAD load
profile(s). These profiles must be different from regular OS load profiles
because the IPL device for SAD is never a sysres volume and may differ from
one LPAR to another. You have the option in an SAD load profile--still, I
think?--to set the Store Status option. The temptation is to set it because
this is by definition a SAD profile. I used to do that until I was advised
otherwise: if the first shot at SAD goes awry for some transitory and
immediately correctable reason, you DO NOT want a second Store Status on
retry. Only the first Store Status, the one from the OS, is of any use
UNLESS you trying to debug SAD itself. BTW I have never once done that in
my whole career.

Can issuing a STORE STATUS directly hurt?
Or does the IPL store status save the exact same data?
