18 hba_dip The dev_info_t pointer associated with the SCSI HBA.

21 level The level of reset required.

25 The tran_bus_reset() vector in the scsi_hba_tran(9S) structure should
26 be initialized during the HBA driver's attach(9E). It is an HBA entry
27 point to be called when a user initiates a bus reset through device
28 control interfaces.

30
31 tran_bus_reset() must reset the SCSI bus without resetting targets.
32
33
34 level will be one of the following:
35
36 RESET_BUS Reset the SCSI bus only, not the targets.
37
38
39
40 Implementation is hardware specific. If it is not possible to reset the
41 SCSI bus without changing the state and operating mode of the targets,
42 the HBA driver should not initialize this vector or return failure.
43
45 tran_bus_reset() should return:
46
47 1 on success.
48
49
50 0 on failure.
