Description IBM Bug Proxy 2010-01-12 10:21:01 UTC
=Comment: #0=================================================
John G. Stultz <johnstul.com> - 
So we were trying to bring up MRG on a new box, and ran into trouble
when the megaraid sas driver wasn't seeming to find the controller.

All we got with kernel-rt-2.6.24.7-146.el5rt.x86_64.rpm was:
-----------------------------------------------------------
megasas: 00.00.03.16-rc1 Thu. Nov. 07 10:09:32 PDT 2007

<no driver messages>
...
<panic, no root device>



Where as with RHEL5.4:
----------------------
SCSI subsystem initialized
megasas: 00.00.04.08-RH2 Tues. May 5, 11:41:51 PST 2009
megasas: 0x1000:0x0079:0x1014:0x03b2: bus 9:slot 0:func 0
ACPI: PCI Interrupt 0000:09:00.0[A] -> GSI 24 (level, low) -> IRQ 177
PCI: Setting latency timer of device 0000:09:00.0 to 64
megasas: FW now in Ready state

I suspect the MRG driver stating that its from Nov 07 might mean its a
bit old. Talked w/ Chris McDermott and he magically knew what commit
*should* fix this:
        git show 6610a6b354d6c3377a1e79cd1d760ffe4358245c

Any chance that this commit could be added?

Rob has tested the -147 kernel with the system in question and it did boot up. I think we can mark this resolved.

This sounds indeed like wonderful news!  I don't mean to be a party killer, but have you done any stress tests with this driver?  I would just like to be sure that we don't regress on both performance and reliability.  After all it's a new controller card which now is supported, which probably means a different firmware and so on.

Comment 6 David Sommerseth 2010-03-17 19:50:46 UTC
Verified by code review.  Found patch mentioned in comment #2 applied to kernel-rt-2.6.24.7-149.src.rpm.
