re-scanning external SATA drive

Sun Aug 2 14:25:49 UTC 2015

	(This is a "Sunday-morning-no-brain" question; didn't find
anything in a quick trip through the Handbook and I'm missing the
magic term(s) for successful Google-fu.)

	I have a workstation that has an external drive connected by
	Trainee house-elves unplugged the drive's power cord, causing
it to no longer be seen even after power was restored.
	Short of rebooting, is there a way to re-scan something and
cause the drive to become available?  (I.e. show up under /dev/gpt)
