[OpenIndiana-discuss] OI and chassis/jbod support?

Hm, we appear to have been discussing a different problem, which is fascinating.

I have a number of devices which are in the Supermicro SC846A-R1200
chassis - which has no expanders, just 6 SFF-8087 ports on it, running
into LSI 9201-16i controllers.

Fascinatingly, attempting to issue a sas2ircu [card] locate A:B on
reports success, but no LEDs blinked at all. I also see no SES devices
to speak of, though the device purports to support SES-2 management.

The backplane [BPN-SAS-846A] spec claims the management chip is the
MG9072, which purports to support in-band SES2 management over SGPIO
or out of band I2C connectors. I know from physically checking that
the former is connected.

This was the problem I was investigating solving.
