Ah. Then I misunderstood the WSAT. I thought only those with the sadump bit on
will be sadump'd. For the others, only MVS will be IPL'd. But I haven't checked
storage. I didn't understand that *any* non-restartable wait state would result
in sadump(parms) mvs(parms).

Reminds me of the customer who complained after taking an sadump for a slip
with a=wait that MVS wasn't restartable afterwards. :-)

Then I must not have seen it. We had been using teh HMC ever since I took over
generating sadump here (after OS/290 2.10).

Yes, I saw the mnote in the assembly. The job ended cc=0, anyway, and I decided
that that's just default behaviour. I found it strnage, though.
Why are others at liberty for incompatible changes?!? (See the stupid health
checker thing that suddenly required a dataset - incompatible change).

*You* know that and *I* know that, but IBM support doesn't. You wouldn't
believe how often I am told that storage is not in the sadump. In many cases it
is a simple case of support being unable to specify the correct dataspace name
when browsing or some IPCS command / addition being unable to access the
dataspace even though it was there. *You* would know how to figure out the
virtual address from a real address. I am not sure I would - I haven't done
enough debugging to stay fluent in it.
And the other general support excuse is that their tools (not IPCS) don't work,
hence storage is not in dump. :-( It is always quite embarassing for them when
I ask why *I* can see the storage but they cannot.

For performance/timing reasons I had held off sadumping all paged out storage.
Anyone out there have numbers how long it takes for a - say - 8GB real lpar
with aux usage at 40% (on 12 locals of 49500 tracks each) in comparison to only
dumping paged-in pages?
(No comments on the 40%, please!)
