TRAN_BUS_RESET(9E) Driver Entry Points TRAN_BUS_RESET(9E)

tran_bus_reset - reset a SCSI bus

#include <sys/scsi/scsi.h> int prefix
tran_bus_reset(dev_info_t *hba_dip, int level);

illumos DDI

hba_dip
The dev_info_t pointer associated with the SCSI HBA.

level

The level of reset required.

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

tran_bus_reset() must reset the SCSI bus without resetting targets.

level will be one of the following:

RESET_BUS

Reset the SCSI bus only, not the targets.

Implementation is hardware specific. If it is not possible to reset the SCSI bus without changing the state and operating mode of the targets, the HBA driver should not initialize this vector or return failure.

tran_bus_reset() should return:

1

on success.

0

on failure.
