Yes and no :).  Actually, it's valid for scsi, sata, and usb block devices,
except.../proc/scsi has been deprecated and is not included in newer kernels
by default.

In newer 2.6 kernels you use:

echo anything > /sys/class/scsi_device/<h>:<b>:<t>:<l>/device/delete
echo "<b> <t> <l>" > /sys/class/scsi_host/host<h>/scan
