3ware driver (3w-xxxx) in 2.6.10: procfs entry

3ware driver (3w-xxxx) in 2.6.10: procfs entry

[Peter Daum]

It looks like in the 3ware driver the procfs entry "/proc/scsi/3w-xxxx"
has been removed (or actually moved to sysfs).
Unfortunately, this breaks all the (binary only )-: tools provided by
3ware, which are indispensable for system maintenance.

Wouldn't it be more appropriate to keep the /proc-entries at least for a
transition period until other tools have been adjusted?

Regards,
           Peter Daum

The change came from the driver maintainer at 3ware.  Get the updated
tools from their website.

Which website do you mean? The programs in the download section of
"www.3ware.com" are just the ones that don't work anymore.

Did you try "Download 'In Engineering Phase' Software" link?

Yeap.  The "idiot" removed the proc interface from the driver before
publishing the updated tools  -- and I said so at the time.  At the time
the interface was removed, the new tools weren't available - period.  They
are still "beta" today (several months later.)

Just put the procfs code back in the driver in your local tree and
walk away.  That's what I did -- but it doesn't look like I commited
it to any BK tree :-( (and that box is *ahem* powered off)

Or just grab the latest (version 9.1.5.2) 3dm and tw_cli software from the
3ware web site.  These may not be listed as being for your version of the
card, but they will work with the new driver.

It's there just a little hidden.  Adam, any chance the new managment tools
could be placed more promimently on the website?

I guess you mean "3ware CLI (version 2.00.00.042+)"?

If this is meant to replace all the other versions on the website, then
the presentation is definitely "suboptimal", because the only way to get
there is to explicitly request "experimental" software for the "9000
series" which is kind of strange if you're just looking for basic
functionality for other controllers.

At least on my 8506-controllers there are also some minor problems (e.g.
"info" doesn't work during a verify) which I thought was due to the fact
that the program is intended exclusively for 9000-controllers.

You should report the problems you find to them.  They do indicate (in
the knowledge base on their web site) that you're going to need the
in-engineering files to run on the latest kernels.  It's only recently
that the newer tools acquired the ability to control older
controllers.

According to a recent post from a 3ware employee on linux-ide-arrays,
a proper release is expected in February.  Obviously the best solution
is that they just give us the source to these tools so that we can fix
them ourselves.  Knowing that isn't going to happen I'm happy they're
at least giving us something while they catch up with the speed of
kernel progress.

I can verify the fact that info is busted when the controller is
verifying the array; I'll gather some more info and pass this on to
3ware.

We have some 3ware 7000 ATA-RAID controllers that I've tested with  
various
versions of the tools trying to get them to work:

It could be that I just completely missed it, but I went to the 3ware
site and chose "7000".  There was not a "CLI" item, so I assumed there
wasn't a specific CLI just for the 7000s.  I later, however, found
that the 9000 CLIs (Normal and In-Eng) worked fine, so I never looked
for any others, such as 8000 or 8500 CLIs.  I may have made a mistake,
but I couldn't find a CLI in the "In Engineering"->"7000" section, and
I had a working solution, so I didn't try elsewhere.

... a little addendum:

while the mentioned "experimental" tw_cli (2.00.00.042) provides at
least basic functionality for some controllers (I mostly use 8506-8)
it does not work at all with 8506-4 controllers (It just complains
"No controller found").
