Hi, I'm trying to make multipath daemon checking asynchronous, and most path checkers use SG. Please bare with some questions on this wild wild topic (to search engine criteria). Is it possible to submit through AIO (libaio API) any SG command forged with struct sg_io_hdr ? I've seen the INQ example in the sg3_utils package, so I guess it should work there. But what about "Test Unit Ready" command ? Also why in the example, only the SG IO write is asynchronous ? Is the inquiry response read qaranteed to be non-blocking ? Would an pread io work at all ? Is there other pointers to code snippets showing these two subsystems together ?
