From: Martin Wilck <mwilck@xxxxxxxx> On SAS expanders, node id's have 3 digits. sysfs paths look like this: /sys/devices/pci0000:80/0000:80:02.0/0000:8b:00.0/0000:8c:09.0/0000:8f:00.0/host9/port-9:0/expander-9:0/port-9:0:13/expander-9:1/port-9:1:12/expander-9:2/port-9:2:4/end_device-9:2:4/target9:0:29/9:0:29:0/block/sdac In that case, we should use the last digit as transport id.
