Hi, Few basic questions on sg driver: 1. Are there any hooks that low level HBA driver needs to implement - for providing support for SG (SCSI generic) driver? Or SG always interacts with scsi_mod and it is transparent to the HBA drivers? >From the tldp How-to and sg.c it looks like it doesn't directly talk with Low level HBA driver, but want to confirm. 2. Can applications talk with SCSI RAID controller device (some targets exposes LUN-0 as controller) through sg interface or it is only for storage devices? 3. How is the mapping between /dev/sda /dev/sdb etc to /dev/sg0 /dev/sg1 etc? Is this information is accessible via procfs or sysfs interface?
