tran_tgt_init

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

Synopsis

#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);

Interface Level

Solaris architecture specific (Solaris DDI).

Parameters

hba_dip

Pointer to a dev_info_t structure, referring to the HBA device instance.

tgt_dip

Pointer to a dev_info_t structure, referring to the target device instance.

hba_tran

Pointer to a scsi_hba_tran(9S) structure, consisting of the HBA's transport vectors.

sd

Pointer to a scsi_device(9S) structure, describing the target.

Description

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.

Return Values

tran_tgt_init() must return:

DDI_SUCCESS

the HBA driver can support the addressed target, and was able to initialize per-target resources.

DDI_FAILURE

the HBA driver cannot support the addressed target, or was unable to initialize per-target resources. In this event, the initialization of this instance of the target device will not be continued, the target driver's probe(9E) will not be called, and the tgt_dip structure destroyed.
