Driver Entry Points                            tran_bus_reset(9E)



NAME
     tran_bus_reset - reset a SCSI bus

SYNOPSIS
     #include  int prefix

     tran_bus_reset(dev_info_t *hba_dip, int level);


INTERFACE LEVEL
     Solaris DDI

PARAMETERS
     hba_dip    The  dev_info_t pointer associated with the  SCSI
                HBA.


     level      The level of reset required.


DESCRIPTION
     The  tran_bus_reset() vector in the scsi_hba_tran(9S) struc-
     ture   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 inter-
     faces.


     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 operat-
     ing mode of the targets, the HBA driver should not  initial-
     ize this vector or return failure.

RETURN VALUES
     tran_bus_reset() should return:

     1    on success.


     0    on failure.
