The SCSI Port driver supplies only one compatible ID, one of the variable-sized generic type codes from the previous table. For example, the compatible ID for a disk drive is as follows: GenDisk. The generic identifier is used in INF files for SCSI devices more than any other, because SCSI drivers are typically generic. Re: Looking for drivers for AMD-RAID Configuration SCSI Processor Device First of all, that's a typo on my part, it's actually the Alienware 15 R3. That said, things did finally get worked out, but not without a bit of pain and suffering. The sg driver registers all SCSI devices (with a current maximum of 256)as they are seen. Each newly registered SCSI device gets allocated thenext available minor device number. At least initially this will be thesame sequence that devices are displayed in mid level's cat /proc/scsi/scsi. The sg devices device mapping can beseen with cat /proc/scsi/sg/devices or cat /proc/scsi/sg/device_strs.
Differences betweencat /proc/scsi/scsi and sg orderings will appear whena low level driver is removed (e.g. rmmod aha1542) orwhen a device is removed with remove-single-device.The sg driver will leave remaining SCSI device mapping to minor devicenumbers unchanged. This potentially leaves a 'hole' in the sg mapping.An example follows:Notice how the sg driver maintains the row positions of the remainingdevices in the 'device_strs' output.
So when the Pioneerdvd player is removed, a hole opens up in the sg device mappingwhich is not reflected in the cat /proc/scsi/scsioutput. That 'hole' corresponds to the device name /dev/sg1.='filename'>='command'>='#000000'>='0'bgcolor='#e0e0e0'width='100%'>='command'>='command'>='command'>='command'>='command'>Īll the following files are readable by all and produce ASCII outputwhen read. The file'def_reserved_size' is also writable by root. The ASCII output has beenformatted in such a way as to be human and machine readable (and hencea compromise). Use Unix commands of the form cat device_hdrs devices to see the output of tables.All the above files are owned by root and readable by all whiledef_reserved_size is writable by root.
