[sles-beta] cciss driver for HP hardware

[Matthias G. Eckermann]

Hello Tom and all,

as already said in my last E-Mail about this topic, we
are taking input on drivers also from the vendor of the
respective hardware.

Regressions on this we try to mitigate, and compared to
other recent distributions, SLES 12 has special code in
the hpsa driver to support more of the older
controllers, i.e. more than the upstream driver.

I just realize that this advice is not reflected in the
Release Notes yet (please file an SR!), thus: please
try "hpsa_allow_any=1" as a kernel commandline option.

This will put the hpsa driver in a mode not supported by
HP (and subsequently not us, see:
https://www.kernel.org/doc/Documentation/scsi/hpsa.txt),
but at least you are able use the device for testing.

I apologize for any inconvenience, but as also said,
this is out of SUSE's control.

so long -
	MgE
