Now ata devices attached with sas controller do not have transport class, so that we can not see any information of these ata devices in /sys/class/ata_port(or ata_link or ata_device). Add transport class for the ata devices attached with sas controller. The /sys/class directory will show the infomation of the ata devices as follows: localhost:/sys/class # ls ata* ata_device: dev1.0 dev2.0 ata_link: link1 link2 ata_port: ata1 ata2 No functional change of the device scanning and io path. The ata transport class was deleted when destroying the sas devices.
