RE: [Xen-devel] FW: megaraid sas driver failing in Xen-3.4 unstable version

["Manyam, Ramesh" <Ramesh.Manyam@xxxxxxx>]

 

I am using 4 port MegaRAID SAS Controller card and only one disk is connected to this controller (only one port we are using). When I tried to bind the device 0000:02:09.0 to pciback driver it saying “no such device”. Is there any other way to bind this device to pciback driver?

 

When I remove MegaRAID SAS Controller card from the machine I couldn’t find this device (02:09.0) in “xm dmesg” after dedicating onboard SAS Controller to Linux HVM.

 

 

 

Thanks,

Ramesh

02:09.0 is just 2:9.0. I found lots of page faults of this device on xmdmesg.

 

Per your lspci -v output, I can know 02:0e.0 is under the PCI bridge 00:01.0.device 02:09.0 is under the same bridge. You must assign all the pci devices under the same PCI bridge to the same guest. But it's curious we cannot find 02:09.0 in lspci whilc there are its DMR page faults. The reason (REASON 2) is that it is not mapped in VT-d context table.

Weidong

I found 2:9.0 in xmdmesg but not 02:09.0

 

Where you found 02:09.0?

 

Yes, 02:09.0 is not showed in lspci –v

 

Why you are so specific to 02:09.0?

 

Device 02:0e.0 is the MegaRAID SAS controller not 02:09.0

Yes I used docs/misc/vtd.txt

 

Device 02:0e.0 is the MegaRAID SAS controller not 02:09.0

 

I am attaching the lspci output and the log messages of Xen & HVM. Please find them with this email

 

Xen log messages (xmdmesg)

HVM guest kernel log messages (hvm_dmesg_with_msi_1^st_time)

Domain0 Kernel log messages (dom0_var_log_messages)

 

Now I destroyed the HVM guest and created HVM guest again

 

HVM guest kernel log messages (hvm_dmesg_with_msi_2^nd_time)

Did you use VT-d followed docs/misc/vtd.txt?

 

Per xmdmesg file, device 02:09.0 didn't be mapped in context sucessfully. Is device 02:09.0 the MegaRAID SAS controller? Can you post "lspci -v" output?

VT-d support is enabled

 

Here I am attaching three files dmesg (hvm dmesgs), dom0_varlogmessages and xmdmesg

 

Thanks,

you mean you assign MegaRAID SAS controller with VT-d to your guest?

 

You'd better provide more info, such as serial output, so people can be easy to help you.

On Xen-3.4 (unstable version), I have created CentOS HVM guest & WS2K8 HVM guest and dedicated MegaRAID SAS controller but I am not able to see the disk which is connected to MegaRAID SAS controller when I do fdisk –l (vtd support is enabled in Xen).

 

Looks like the pci device(MegaRAID SAS controller) is getting dedicated successfully as I can see the device in the list of pci devices shown by lspci(on CentOS HVM).

 

00:06.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS

 

 

However the driver is not getting attached properly and fails with the following error

 

=======================================================================================

“dmesg” of HVM CentOS

megasas: Failed to init firmware

ACPI: PCI interrupt for device 0000:00:06.0 disabled

 

 

“/var/log/messages”

 ACPI: PCI interrupt for device 0000:02:0e.0 disabled

=======================================================================================

 

 

 

On WS2K8 HVM, I am able to see MegaRAID SAS controller under “Storage Controllers” on WS2K8 HVM and the status of device is

 

=========================================================================================================================================================

This device cannot start.(Code 10)

Description:

 Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run. The problem code is

And also I am not able to see the disk which is connected to MegaRAID SAS controller
