SCSI_RESET_NOTIFY(9F)SCSI_RESET_NOTIFY(9F)NAMEscsi_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 noti‐
fication request.
callback
A pointer to the target driver's reset notification func‐
tion.
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 con‐
troller) 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 func‐
tion for the target driver.
SCSI_RESET_CANCEL
Cancel the reset notification request.
Target drivers can find out whether the HBA driver and controller sup‐
port 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.
CONTEXT
The scsi_reset_notify() function can be called from user, interrupt, or
kernel context.
