Dear All,
I have one Adaptec 1405 card with a Marvell 88SE6440 chip (mvsas). The
card has one SFF-8087 connector with integrated I2C/SGPIO. On the other
side my cable is SFF-8484 and connected to one simple 4x SAS/SATA
backplane without RAID logic (sas/sata lines are directly routed to
HDDs).
The problem with the backplane is that it controls SATA's pin 15 and the
hard drives do not spin-up unless instructed to. This operation is
handled by a PCA9556 chip located directly on the backplane.
My question is, how can I talk to this PCA9556 chip using mvsas driver?
Or alternatively, where to get info, what needs to be written for
"mvsas" to get this working?
Sincerely,
Dennis
