tran_quiesce(9e)						Driver Entry Points						  tran_quiesce(9e)

NAME

       tran_quiesce, tran_unquiesce - quiesce and unquiesce a SCSI bus

SYNOPSIS

       #include <sys/scsi/scsi.h>

	int prefixtran_quiesce(dev_info_t *hba_dip);

       int prefixtran_unquiesce(dev_info_t *hba_dip);

INTERFACE LEVEL

       Solaris DDI

PARAMETERS

       hba_dip	       The dev_info_t pointer associated with the SCSI HBA.

DESCRIPTION

       The   tran_quiesce()  and   tran_unquiesce()  vectors  in  the  scsi_hba_tran(9S)  structure  should be initialized during the HBA driver's
       attach(9E). They are HBA entry points to be called when a user initiates quiesce and unquiesce operations  through  device  control  inter-
       faces.

       tran_quiesce() should wait for all outstanding commands to complete and blocks (or queues) any I/O requests issued. tran_unquiesce() should
       allow I/O activities to resume on the SCSI bus.

       Implementation is hardware specific.

RETURN VALUES

       tran_quiesce() and tran_unquiesce() should return:

       1	on success.

       0	on failure.
