Description of problem:
latest 3ware controller firmware wants driver version 1.02.37, but
fedora uses driver version 1.02.36.
the problem is that 3ware states on its homepage the actual firmware
for the 7000 controller wants 1.02.37.
it would be great to have the new version with a forthcoming
fedora-core 2.4-kernel (2.6 uses 1.02.36).
ps.: the newer versions compiles fine and works on my 7000 controller.
but i dont now what happens if i would try to use the fedora-driver.

original driver from 3ware
Created attachment 97100 [details]
diff onto 2.4.22-1.2149
3Ware also recommends installing the latest driver when doing firmware
upgrades and the latest firmware is newer than the driver which ships
unfortunatly this means that existing users will find after upgrading
that they needed to flash newer firmware too. WONTFIX.
I've contacted 3Ware and the answers I've received from them suggest
reopening this bug.
Here's the answer of their support engineer:
From a technical support stand point we recommend to use matching code
For example. The 7.7.0 software release is made up of the following
7.6.3 Software release is made up of:
And so on....
And so on. You can have the oldest firmware with a 7500-8/4/12/7000-2
or 7506-8/4/12/7006-2 and run the latest driver 1.02.00.037. It will
ever it has not been tested. Once up and running we recommend to
update accordingly (yes including firmware).
The same goes for an old 8500 series controller.
The 7500/7506 series controller share the same software release.
The 8500/8506 series controller also share the same software release.

OK, I'll post that, but I have only 2 more questions:
* what about 8000 and 8500 series controllers? We have 8506-4 and
8506-8 on 2 servers. In general, coule there be backward/forward
compatibility issues with _any_ of controllers supported by that
driver (I think this is what Redhat people had in mind, all 3Ware
controllers, not only 7000)?
* Fedora Core 1 uses .036 driver, but Redhat Enterprise Linux uses
.033 driver. Is it ok to upgrade .033 to .0.37 without having to
update the firmware? If yes, then the Enterprise Linux driver
could be freely updated too by Redhat people.
