The i2o_scsi OSM module is a SCSI HBA driver that supports the SCSA interface.
It supports both SCSI Adapter Class and SCSI Peripheral Class functions. It translates the SCSI packet coming down from the SCSA into an I2O SCSI Peripheral Class message, passes it along to the IOP which in turn passes it to the HDM (hardware specific module).
It also uses SCSI Adapter Class functions to manage the SCSI adapter and SCSI bus. For each SCSI Adapter Class I2O device (a SCSI controller), it claims the SCSI Peripheral class devices which are attached to that port. The existing SCSI target drivers which use the SCSA interface should only work with i2o_scsi. This includes target drivers like sd, st and so on.
