RHEL4 U2: Serial Attached SCSI (SAS) support (HW)
Last modified: 2007-11-30 17:07:11 EST
Dell will have product offerings utiilizing Serial Attached SCSI (SAS)
controllers and will need drivers. More details TBD.
*** Bug 108336 has been marked as a duplicate of this bug. ***
Need hardware (HBAs and disks). Is code upstream? Needs to be upstream and
accepted by A2 (date TBD).
RHEL4 feature review meeting - must remain in needinfo. We have neither
hardware nor code at this point.
They have missed the deadline for RHEL4. Systems may work with RHEL4, but we
can't guarantee it at this point, nor will it be a fully-supported configuration.
Kevin, what's the story on SAS in RHEL4 at this point?
I have received the hardware.
I have also briefly reviewed fusion-3.02.18.tgz posted in IT 68878.
Just so everyone is on the same page, the upstream 2.6 mpt fusion driver is
being split up into separate drivers for SCSI, FC, SAS. This is a large, risky
change that is not appropriate or compatible with the infrastructure in RHEL 4.
So, for this driver, our priority is not to push LSI Logic to "get it accepted
upstream", but rather to push them to provide us with small, safe, minimal,
patches for bug fixes and new hardware support, compatible with the RHEL 4 kernel.
The good news is that the driver in fusion-3.02.18.tgz file is an update for the
monolithic driver in RHEL 4 (it is not the split-up driver proposed for
upstream). The bad news is that the diff is 15,000 lines of code(!). Does LSI
Logic really beleive that they can update production, enterprise, customers from
the version in RHEL 4 to 3.02.18 without regression? How much testing have they
done on the older hardware?
If we commit to this for U2 it will require a significant amount of time for
code review, testing, and partner testing.
Okay, I have reviewed the code and started the testing. This looks good for
inclusion in U2, assuming 1) no serious problems arise, and 2) our partners
follow through on the regression testing they promised.
PM ACK for U2.
A patch to update the mpt fusion driver to 3.02.18 was added to the U2 code
base, in kernel 2.6.9-11.1.

I've hit another bug that impacts the issue below. Hopefully I'll have an
answer for you this week.
This was checked in to U2 quite a while ago:
* Thu Jun 2 2005 Dave Jones <email@example.com> [2.6.9-11.1]
- U2 begin.
- Update mpt fusion driver, include SAS support. (FZ107088)
