tran_tgt_init - request to initialize HBA resources on behalf of a particular target

#include <sys/scsi/scsi.h>



int prefixtran_tgt_init(dev_info_t *hba_dip, dev_info_t *tgt_dip,
 scsi_hba_tran_t *hba_tran, struct scsi_device *sd);

illumos architecture specific (illumos DDI). hba_dip tgt_dip hba_tran sd The tran_tgt_init() vector in the scsi_hba_tran(9S) structure may be initialized during the HBA driver's attach(9E) to point to an HBA driver function to be called by the system when an instance of a target device is being created. The tran_tgt_init() vector, if not NULL,is called after the dev_info node structure is created for this target device instance, but before probe(9E) for this instance is called. Before receiving transport requests from the target driver instance, the HBA may perform any initialization required for this particular target during the call of the tran_tgt_init() vector.

Note that hba_tran will point to a cloned copy of the scsi_hba_tran_t structure allocated by the HBA driver if the SCSI_HBA_TRAN_CLONE flag was specified in the call to scsi_hba_attach(9F). In this case, the HBA driver may choose to initialize the tran_tgt_private field in the structure pointed to by hba_tran, to point to the data specific to the particular target device instance.

tran_tgt_init() must return: DDI_SUCCESS DDI_FAILURE attach(9E), probe(9E), tran_tgt_free(9E), tran_tgt_probe(9E), scsi_hba_attach_setup(9F), scsi_device(9S), scsi_hba_tran(9S)
