tran_bus_reset(9E) Driver Entry Points tran_bus_reset(9E)NAMEtran_bus_reset - reset a SCSI bus
SYNOPSIS
#include <sys/scsi/scsi.h> int prefix
tran_bus_reset(dev_info_t *hba_dip, int level);
INTERFACE LEVEL
Solaris DDI
PARAMETERS
hba_dip The dev_info_t pointer associated with the SCSI HBA.
level The level of reset required.
DESCRIPTION
The tran_bus_reset() vector in the scsi_hba_tran(9S) structure should
be initialized during the HBA driver's attach(9E). It is an HBA entry
point to be called when a user initiates a bus reset through device
control interfaces.
tran_bus_reset() must reset the SCSI bus without resetting targets.
level will be one of the following:
RESET_BUS Reset the SCSI bus only, not the targets.
Implementation is hardware specific. If it is not possible to reset the
SCSI bus without changing the state and operating mode of the targets,
the HBA driver should not initialize this vector or return failure.
RETURN VALUEStran_bus_reset() should return:
1 on success.
0 on failure.
