There is a program in SLES8 (was also in SLES7) called flushb that appears
to be useful for flushing the memory buffers on a per disk device basis.
There is precious little documentation on this particular tidbit out there,
however, I did find this link where the sources is posted:
Sorry, should have seen this discussion earlier. Since the majority
of z/VM's control program (CP) is still 31-bit addressing, a guest page
that CP is working with will tend to be brought below the 2GB bar.
There are always exceptions of course.

I was wondering if anyone here could do a little test for me.
We have 2 environments. We've noticed that on our z900-escon-EMC
DMX2000 DASD, dasdfmt of 10,000 cyl takes an awful long time - 25minutes

On our z990-ficon-HDS DASD,

By chance do you have both sets of .iso files on the same system? It would
be interesting to diff each pair of CDs. It's possible the first set is
corrupted, but I have yet to see a corrupted byte from a completed FTP. If
Thanks.
As it happens, even rush order of DVDs will take some 10 days. By the
time the media arrives (Nov 11 is the ETA), we would be ready to gen some

Our z/VM environment includes the vols we genned into our Linux LPAR. I am
assuming that after the VM install, we can create a guest and map the
minidisks to the vols currently used by the Linux LPAR and bring it up as
a guest. Will this work?
I presume that I would have to change some config
Hi James
OK, I presume that
