[geeks] OK, so now *I* have a SCSI problem

[Lionel Peterson]

Technically you have a SAS/SATA problem... I'm uncertain of the correct animal
to sacrifice for those problems.

Are there any loose connections in the chassis?

I think the issue is going to be settings/functions on controller card,
because the chassis simply extends the drive connector back to the
controller.

It sounds like a port-multiplier related issue, but this is SAS wiring, not
SATA...

Odd. Sorry I couldn't be of more help.
