While it certainly is possible for IBM to rewrite WAIT/POST to use the PLO

You don't mention if these drives are inside an ATL or not. That will make a

The bottom line is that one task needs to be suspended until some event

If your existing drives are FICON attached, probably not. If ESCON
attached, you really want to go FICON. A single 3590H drive, with
compressible data on tape, can easily outperform ESCON throughput. 3590

The answer to your first paragraph is: Yes. -- Except that the ECB isn't
passed in as a parameter, nor should it be. You would have to pass that
address to your attached task as part of a parameter list, but I can't think
of any reason you would do that.
Terry,
So you're saying that with IBM Storage, CFW is not remitted to the Remote
Storage. If you turn it off then it just becomes another DFW.
With HDS this was always an option.
BTW, CFW will be destaged to disk just like any other write. A cache Fast
write is only written to Cache and not NVS
Let me see if I am understanding it all. There really isn't a need for
the daughter task to POST because the system does automatically when the
daughter process ends. And just about the only information that the
daughter can get from the ECB is whether the parent has issued a WAIT or
not.

When the daughter is entered, the ECB address will be off of R1.

R2 should now have the address of the ECB. You can use this to POST
different return codes, should your logic require it.
