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.
