NAME
     scsi_reset_notify - notify target driver of bus resets

SYNOPSIS
     #include 



     void scsi_reset_notify(struct scsi_address *ap, int flag,
          void (*callback)(caddr_t), caddr_t arg);


INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI).

PARAMETERS
     ap          Pointer to the scsi_address structure.


     flag        A flag indicating registration  or  cancellation
                 of the notification request.


     callback    A pointer to the target driver's reset notifica-
                 tion function.


     arg         The callback function argument.


DESCRIPTION
     The scsi_reset_notify() function is used by a target  driver
     when  it  needs to be notified of a bus reset. The bus reset
     could be issued by the transport layer (e.g.  the  host  bus
     adapter (HBA) driver or controller) or by another initiator.


     The  argument flag is used to register or cancel the notifi-
     cation. The supported values for flag are as follows:

     SCSI_RESET_NOTIFY    Register callback as the reset  notifi-
                          cation function for the target driver.


     SCSI_RESET_CANCEL    Cancel the reset notification request.



     Target drivers can find out whether the HBA driver and  con-
     troller  support  reset notification by checking the  reset-
     notification capability using  the  scsi_ifgetcap(9F)  func-
     tion.

RETURN VALUES
     If flag is SCSI_RESET_NOTIFY, scsi_reset_notify() returns:

     DDI_SUCCESS    The notification request has been accepted.


     DDI_FAILURE    The transport layer does  not  support  reset
                    notification   or   could   not  accept  this
                    request.



     If flag is SCSI_RESET_CANCEL, scsi_reset_notify() returns:

     DDI_SUCCESS    The notification request has been canceled.


     DDI_FAILURE    No notification request was registered.


CONTEXT
     The scsi_reset_notify() function can be  called  from  user,
     interrupt, or kernel context.
