pc 3 is used by sd driver to get physical geometry. If the scsi disk doesn't support it, maybe you should support virtual geometry in your HBA driver, so that sd(7d) driver can fallback to virtual geometry. You can try implementing SCSI_CAP_GEOMETRY </source/s?defs=SCSI_CAP_GEOMETRY> in tran_getcap(). BTW, what HBA driver you are writing ? Good luck, -minskey > Steve > > > > _______________________________________________ > driver-discuss mailing list > [email protected] > http://mail.opensolaris.org/mailman/listinfo/driver-discuss > _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
