Did you get this to work? I can't get it to light up any LEDs, though
the LEDs do light when the drives are active.
In case anyone wants to understand how the device names works, see
this excellent presentation:
http://www.jmcp.homeunix.com/~jmcp/WhatIsAGuid.pdf
Even if the LEDs lit up, how would this help determine which drive is
which? The only identifying features of the drive are the slot and
serial number, but OpenSolaris doesn't seem to know that information.
OpenSolaris does know that information, *if* it has support
for your enclosure in the FMA frame of reference.
What I have learned is that is that you can simply use dd
if=/path/to/drive of=/dev/null to read stuff off the drive into oblivion
and it will cause the LED to blink crazy. So you can do this
systematically and build a complete map of your drive locations.
True, you could do that. You could also pull in the sestopo
utility, found in system/io/tests, and run that against your
ses node.
