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

Interface Level

Solaris DDI specific (Solaris DDI).

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 capability using the scsi_ifgetcap(9F) function.

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.
