It appears that the operations of 'add single device' and 'remove single device' via the procfs are no longer available/provided by some HBA drivers in the 2. 6 kernel. Is there some equivalent function to cause re-instancaion of devices for a specific bus and or HBA? I work on a unit test program wherein a RAID controller appears on a bus as target 0, lun 0, device type 3 or 13 with an sg path, but when a logical drive is created it is now target 0, lun 0 with a logical drive ID. In most cases, a 2.6 kernel does not seem to see this target lun with an appropriate '/dev/sdX' path and device type 0. Should I expect that issuing an ioctl SG_SCSI_RESET for the host, bus or device to the initial sg path accomplish what I need? Thanks in advance for any input.
