Eric,
This attached patch should do DV on both physical devices and the
underlying devices of fusion IM assemblies (providing you apply it on
top of the prior underlying device exposure patch), which, I believe was
your only outstanding concern with the last generic DV patch.
There is one slight unsightly piece: the IM device still attaches to the
transport class however all the parameters it shows actually belong to
the underlying device at that id ... I could do with finding a way of
persuading the SPI transport class not to attach to RAID devices.
Since this addresses all of LSI's prior concerns, may I now apply it?
James

Roy/Laura/Roy/Steve, and others - This is a patch to remove our
internal dv(domain validation) code and replace with generic
dv implemention in the linux kernel. This is a year old push from
kernel.org , for the drivers in upstream kernel.
James: I've not been able to review this patch, nor the other one you sent.
On concern is whether spi transport handle asyn events? Meaning will it do
domain
validation on RAID1 volume - for a new drive that was hot swapped with a
good disk? In the driver look at mptscsih_event_process - this code is
handling a aync event from the firmware telling the driver to perform
dv on disk that was just added.
Pls don't rush this into the kernel untill we have time to review, and/or
talk to our internal test teams on test effort, and/or talk to our customers
explaning the risk in removing this code.

Yes ... I think I told you this the last time you asked. You just have
to plug in either spi_dv_device() or spi_schedule_dv_device() (if you're
in interrupt context) and it will kick off a dv of the underlying
device.
It is hard for me to ascertain what the firmware is doing from reverse
engineering the driver since you don't provide documentation. However,
I can guess roughly from the original code what to do. How do I trigger
this event to test it?

Well, apart from the update to do DV on underlying raid devices, which
is really all in the previous patch, nothing much has changed from the
diff I sent you on 11 April ... I haven't heard that you found any
problems in your previous four months of testing, how much longer do you
need?
The object of using the generic code is to try to pool resources on DV
since it's a rather complex and bug prone area. I already know you have
several bugs in the fusion DV code, of which hanging the system when
there's a narrow segment in the domain is the most serious. However, I
suspect we probably have different tests in our DV test suites, so if
yours turns up any problems in the generic DV, I'll be happy to fix it.

- there's a stale printk("HERE2\n"); in mptscsih_writeSDP1.
- the #undef MPTSCSIH_ENABLE_DOMAIN_VALIDATION is probably not needed
- the hd == NULL check in mptspi_target_alloc isn't needed
- should the driver print a warning about too old firmware when we can't
access page 0?

Yes, sorry, I'll remove it

There's actually an awful lot of other cruft besides this that can come
out of the driver (inquiry snooping leaps to mind).

Yes, OK.

I'll defer to LSI on this one. We can't attach the transport classes in
this case ... which is what I do. But on the other hand, LSI didn't do
DV in this case either, so the current situation is identical to what we
had previously.
But yes, this type of situation seems quite common. The fusion card HP
sent me initially had this problem, and it does seem to be possible to
upgrade all the problem cards, so reporting the issue and recommending
an upgrade seems to be a good approach.

James: Your patches are not applying cleanly, so tell which kernel do I use

I don't use git to get the source, I'm pulling patches from www.kernel.org.
I've tried:

If you start with 2.6.13-rc6, you should be able to apply scsi-misc on
top of that, the patch is at:
http://www.kernel.org/pub/linux/kernel/people/jejb/scsi-misc-2.6.diff
Then the fusion DV patches should apply on top of that.

OK, I managed to code and test this. Have a look at the attached. It
combines both the raid device exposure and the DV code (the patches got
rather hopelessly entangled while I worked on them).
This is what we now show for a RAID device with the underlying physical
disks appearing on the virtual channel:
mptbase: Initiating ioc0 bringup

Attached scsi generic sg4 at scsi7, channel 1, id 1, lun 0, type 0
And this is what happens if I remove and reinsert one of the RAID
devices:
target7:1:1: Integrated RAID requests DV of new device

target7:1:1: Ending Domain Validation

I also added back the RAID quiesce that the old code did while
performing DV.
