As I wrote before, I'm > interested in how HP SCSI driver does. We don't neccesarily want or need to expose the physical disks. The only exception is disks that are not part of a logical volume. If the disks are part of a logical volume but exposed the user may shoot themselves in the foot by destroying the firmware metadata. -- mikem -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
