NAME

       scsi_reset_notify - notify target driver of bus resets

SYNOPSIS

       #include <sys/scsi/scsi.h>

       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 notification function.

       arg	       The callback function argument.

DESCRIPTION

       scsi_reset_notify()  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 notification.  The supported values for  flag are as follows:

       SCSI_RESET_NOTIFY       Register callback as the reset notification function for the target driver.

       SCSI_RESET_CANCEL       Cancel the reset notification request.

       Target drivers can find out whether the	HBA driver and controller support reset notification by checking the  reset-notification  capabil-
       ity using the  scsi_ifgetcap(9F) function.

RETURN VALUES

       If  flag is  SCSI_RESET_NOTIFY, scsi_reset_notify() returns:

       "small and bold">DDI_SUCTheSnotification 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:

       "small and bold">DDI_SUCTheSnotification request has been canceled.

       DDI_FAILURE	       No notification request was registered.

CONTEXT

       scsi_reset_notify() can be called from user or interrupt context.
