mpt_register(9) [centos man page]

MPT_REGISTER(9) 					       Message-based devices						   MPT_REGISTER(9)

NAME
mpt_register - Register protocol-specific main callback handler. SYNOPSIS
u8 mpt_register(MPT_CALLBACK cbfunc, MPT_DRIVER_CLASS dclass, char * func_name); ARGUMENTS
cbfunc callback function pointer dclass Protocol driver's class (MPT_DRIVER_CLASS enum value) func_name call function's name DESCRIPTION
This routine is called by a protocol-specific driver (SCSI host, LAN, SCSI target) to register its reply callback routine. Each protocol-specific driver must do this before it will be able to use any IOC resources, such as obtaining request frames. NOTES
The SCSI protocol driver currently calls this routine thrice in order to register separate callbacks; one for "normal" SCSI IO; one for MptScsiTaskMgmt requests; one for Scan/DV requests. Returns u8 valued "handle" in the range (and S.O.D. order) {N,...,7,6,5,...,1} if successful. A return value of MPT_MAX_PROTOCOL_DRIVERS (including zero!) should be considered an error by the caller.

tran_reset_notify(9E)						Driver Entry Points					     tran_reset_notify(9E)

NAME
tran_reset_notify - request to notify SCSI target of bus reset SYNOPSIS
#include <sys/scsi/scsi.h> int prefixtran_reset_notify(struct scsi_address *ap, int flag, void (*callback, caddr_t),caddr_t arg); INTERFACE LEVEL
Solaris architecture specific (Solaris DDI). PARAMETERS
ap Pointer to the scsi_address(9S) structure. flag A flag indicating registration or cancellation of a notification request. callback A pointer to the target driver's reset notification function. arg The callback function argument. DESCRIPTION
The tran_reset_notify() entry point is called when a target driver requests notification of a bus reset. The tran_reset_notify() vector in the scsi_hba_tran(9S) structure may be initialized in the HBA driver's attach(9E) routine to point to the HBA entry point to be called when a target driver calls scsi_reset_notify(9F). 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. SCSI_RESET_CANCEL Cancel the reset notification request for the target. The HBA driver maintains a list of reset notification requests registered by the target drivers. When a bus reset occurs, the HBA driver notifies registered target drivers by calling the callback routine, callback, with the argument, arg, for each registered target. RETURN VALUES
For SCSI_RESET_NOTIFY requests, tran_reset_notify() must return DDI_SUCCESS if the notification request has been accepted, and DDI_FAIL- URE otherwise. For SCSI_RESET_CANCEL requests, tran_reset_notify() must return DDI_SUCCESS if the notification request has been canceled, and DDI_FAILURE otherwise. SEE ALSO
