There is no real supported way to access private storage in another address space uninvited.
The general consensus amongst developers, typically ISVs, who are confronted with this requirement is to schedule a SRB into the target ASID and use some sort of shared memory buffer to relay the information back to the caller, e.g. shared memory, 64bit common or dataspace. There has been a few threads on IBM-Main about this over the years and I think I may have added a few words on the subject.
