Hi All,


I'm trying out -CURRENT on an IBM HS21 blade. So far the machine looks stable.

Only thing that bothers me is the message as stated above.

Is this something to worry about?


The LSI Logic controller in question is configured as a hardware RAID-0

Informations about the controller:

PS.: FWIW, Linux 2.6.20 had severe problems with this specific mpt controller - patches came with Linux 2.6.21

Looks like the LSI Logic stuff isn't very well supported. On the other hand, there's now way around them when using IBM blades :(

Same counts for the bce(4) NIC.

IIRC both mpt(4) and bce(4) have vendor supported drivers, so I'd be

surprised if they didn't work well. Here at work, we had some issues

with a bce(4) device in about 20 of our Dell boxes running RELENG_6_2

and David Christensen (Broadcom employee) helped fix them and make them

work lovely (allowing us to cancel an order of ~20 PCIE em cards :)

I didn't know that. Thanks for the Heads Up :-)

No, it's nothing to worry about.  The message can probably be put under


Are you saying that the LSI Logic stuff is not well supported in FreeBSD

or in Linux?  Neither statement would be at all true.  Same with BCE,

it's quite well supported.


Scott

Hi Scott,


Well, both the SAS part of mpt(4) and the functionality for BCM5708S weren't available in FreeBSD 6. Of course, this doesn't obviously mean that they're not well supported.

In regards to the specific mpt(4). It got patches in Linux 2.6.21 to get it working.


Since I can't provide details, let's stick with: Great to see that both, the mpt(4) and the bce(4) (the specific ones used in HS21 blades) are supported.

I already did some stress testing with MySQL in a production replication setup and everything looks stable.

So far, so good.

If I encounter any problems (panics, whatever) I'd be glad to help out with testing and testing and testing :)

But they work in STABLE.

All I had to do was to download a STABLE-snapshot.

(CURRENT is a no-go in production here)


Until now, no problems have occured. But we don't do a lot of local disk

I/O on them, IIRC.


cheers,

Rainer

No problems here either. Lot's of disk I/O due to heavy mysql replication setup with InnoDB and MyISAM mixed.

At a first glance, everything was stable and as fast as the very same MySQL + my.cnf + Linux 2.6.21 on the same hardware.

Good News that :)


Cheers,

Marian

I think I've run LSI SAS under 6.2 just fine. The newer "serdes" BCMs

are supported on 6-STABLE (i.e. added after 6.2 was released).

On the other hand, 7-STABLE was branched today (unfortunately without my

favorite patches) so most new users will want to go with it...

So RELENG_7 exists as of today?

Then it really makes sense for me to do my testing without FreeBSD 6 :)


Well, on for some stress testing on this box :-)


Cheers,

Marian
