I have a 6 slot server case with a backplane. AFAICT the backplane is
passive and there are SATA cables that lead from the backplane to the mobo.
The problem is that the disk activity LEDs for the slots don't flash at
all. The mobo is an ASUS M2N SLI Deluxe, which has the MCP55 controller.
The drive activity LED which plugs into the mobo works just fine; the
individual LEDs for each of the drives don't flash - they just stay on.
Is there something I can enable to make them work? Or is the backplane
broken?
The backplane may be expecting the host to control the LEDs. You'd have
to check with the manufacturer to be sure. As for how it would do this,
there's such a thing as enclosure management support in SATA, but the
sata_nv driver doesn't support it. If there is a way to use it on that
controller, only NVidia would know, since they've provided no
documentation for their pre-AHCI controllers. Some AHCI controllers do
have support for this..
