LSI Logic SAS1064 PCI-X Fusion-MPT SAS

[Steffen Weber]

I´m trying to install Linux 2.6.15 on a Sun Fire X4100, which has a 
Serial Attached SCSI (SAS) controller from LSI Logic:

LSI Logic / Symbios Logic SAS1064 PCI-X Fusion-MPT SAS (rev 02)

I have enabled the following kernel config options:
CONFIG_FUSION=y
CONFIG_FUSION_SAS=y
CONFIG_FUSION_MAX_SGE=128
CONFIG_SCSI_SAS_ATTRS=y

When booting the controller is detected, but he does not see the disks:

...
Fusion MPT base driver 3.03.04
Copyright (c) 1999 - 2005 LSI Logic Corporation
Fusion MPT SAS Host driver 3.03.04
GSI 20 sharing vector 0xC9 and IRQ 20
ACPI: PCI Interrupt 0000:02:03.0[A] -> GSI 28 (level, low) -> IRQ 16
mptbase: Initiating ioc0 bringup
ioc0: SAS1064: Capabilities={Initiator}
scsi0 : ioc0: LSISAS1064, FwRev=01040000h, Ports=1, MaxQ=511, IRQ=16
...
[There is nothing releveant to the controller here]
...
VFS: Cannot open root device "sda4" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(0,0)

I´ve tried Linux 2.6.14 with no success, too. What could be the cause 
that the disks are not detected?

Please cc me as I'm not subscribed to linux-scsi.

Thanks,
Steffen Weber

Are the disks belonging to a RAID volume?

Yes, they do! What does that mean for our situation?  :-)

The RAID support is not there yet, and I'm working on it. Hopefully
in the next week.  I'm in dicussions with Christoph Hellwig on this.

Meanwhile, I suggest that you use the LSI internally supported drivers
which has RAID support. I will send that to you in a seperate email.

I just want to let everybody else who runs into this problem know that 
this "internally supported driver" works fine! :-)

Again, thank you very much, Eric!

Hi,

I found Steffens posting on the linux-scsi list and I just wanted to ask 
if RAID support for mptsas has already been added.
If not I guess there's still a need to merge the LSI drivers with the 
official kernel.org ones. Eric and/or Christoph have you continued 
working on this? I could "offer" a student that may work on this but he 
has only limited C skills (which is much more than I have =).

Regards
Bjoern

Yes, it is in mainline since 2.6.16 if I remember correctly.
