Mark,
I struggled with a port multiplier in a similar configuration (but older
chipset) until I finally gave up, bought an 8 port card and bypassed it
with a lovely sata octopus. :( I even started hacking at the driver
code where I found some things that seemed unfinished but was never
totally successful. This was back around build 121 so things may be
better now. I doubt it because there wasn't much interest in getting
this feature working. Sorry I can't give you the magical incantation to
get things going.

I have been trying to get the si3124 driver working with port
multipliers using the si3826 chipset.
The driver source suggests port multipliers are supported.
The card's are seen, driver loads, but no disks.
The controller ports with multipliers connected show as failed.
The server is the Backblaze Pod 3.0 system using Syba PCI Express SATA
II 4-Port RAID Controller Card SY-PEX40008 and AC-SAN-5PMBP 5 Bay Port
Multiplier Backplane (Sil 3826 Chipset).
No issues when I tried running Nas4Free, but FreeBSD doesn't support
the application I want to use for the storage.
I did try turning on debugging, but as a beginner at driver debugging
I'm not sure I achived the desired result and got no useful info from it.
Anyone have experience with Sata Port Multipliers and can share a few
pointers ?
Mark.
