I have a sata_sil24 problem involving a 4-port SI3124-based controller
connected to a 3-port eSATA enclosure. Each eSATA port is an SI
4726-based H/W PMP. The PMPs are connected to (13) 1 TB hard drives, as
indicated below.

PCI3124 Port 1
4726 (Configured in RAID10 mode)
4726 Port 1 => 1 TB drive
4726 Port 2 => 1 TB drive
4726 Port 3 => 1 TB drive
4726 Port 4 => 1 TB drive
4726 Port 5 => 1 TB drive
PCI3124 Port 2
4726 (Configured in RAID10 mode)
4726 Port 1 => 1 TB drive
4726 Port 2 => 1 TB drive
4726 Port 3 => 1 TB drive
4726 Port 4 => 1 TB drive
4726 Port 5 => 1 TB drive
PCI3124 Port 3
4726 (Configured in JBOD/Passthru mode)
4726 Port 1 => 1 TB drive
4726 Port 2 => 1 TB drive
4726 Port 3 => 1 TB drive
4726 Port 4 => no connection
4726 Port 5 => no connection
PCI3124 Port 4 =>no connection

I am running openSuse 11.0 with a 2.6.27.7-4.1 kernel

For the 4726 PMP configured in JBOD mode, all is well, and I can see all
3 disks.

However, for the 4726 PMPs configured in RAID10 mode, I can see NONE of
the disks.

As I understand it, the 4726 is a hardware-based PMP which can handle
RAID10 by itself and thereby offload the RAID processing. I would expect
the 3124 controller to see the drives hidden behind the 4726 as a single
unit, but this does not happen. Instead I get the errors listed at end,
and the RAID10 device is not 'seen' at all. (Key error of note is "both
IDENTIFYs aborted, assuming NODEV")

JBOD is fine for host-only based RAID functionality, but I want the
higher performance the 4726 offers for RAID10.
Is is not possible to off-load the RAID10 function to the 4726 under linux?

Any help, workarounds (beyond strict JBOD mode) are appreciated.

Thanks!
