I have an external enclosure with an SATA backplane with 20 drive
slots. I am using 4 port multipliers to drive all 20 slots.
One set of 5 slots connected to a single port multiplier always fails with

I've swapped cables, port multipliers, and so on. It's not the
backplace, as I can swap cables from one of the port multipliers that
works and it will detect drives. It's not the port multiplier, as I've
swapped those. The only thing I can think of is that it's failing
initialization. If I swap cables from a port multiplier that's
initialized while the system is running, it works.
Before I start taking random actions, can someone interpret the above
for me? What's it telling me?
For comparison, here's the initialization sequence from the adjacent
port multiplier:
[ 16.449504] ata1: FORCE: PHY spd limit set to 1.5Gbps

If I swap cables from ata1 to ata2 while the system is running, the
backplane will detect drives and work fine.
I'm already forcing a slower speed:
yan@selene:/etc/modprobe.d$ cat libata
options libata force=1.15:1.5Gbps,2.15:1.5Gbps,3.15:1.5Gbps,4.15:1.5Gbps
I'm using a Sil 3132 controller:
02:00.0 Mass storage controller: Silicon Image, Inc. SiI 3132 Serial ATA
Raid II Controller (rev 01)
The system sees 3 port multipliers; not 4 as it should:
[ 82.488354] ata4.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports,
feat 0x1/0x9
[ 82.488507] ata3.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports,
feat 0x1/0x9
[ 82.796408] ata1.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports,
feat 0x1/0x9
I suspect it's cabling length as the 5 "dead" slots are the farthest
down the backplane but swapping cables randomly just doesn't seem like a
good approach.
What's my next step?
Thanks,

..
Perhaps try a different chipset controller card,
in hope that it will have stronger drive capability?

OK, did that. No joy.
[ 82.533526] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310)

[ 82.533686] ata3: reset failed (errno=-11), retrying in 9 secs
Is there some way to be more forceful with the reset? I suspect one of
the port multiplier boards is bad at this point. Is there some way to
force a hard reset from user space? What can I from userspace short of
hitting the thing with a hammer?

ATA already uses hardreset. You can trigger it by echoing "- - -" to
/sys/class/scsi_host/hostN/scan but I doubt it would do any good. :-(
