IOCINFO (Device Information) tmssa Device Driver ioctl Operation
Purpose
To return information about the device in a structure that is defined in the
/usr/include/sys/devinfo.h file.
Description
This operation allows you to supply a pointer to the address of an area of type struct
devinfo in the arg parameter to the IOCINFO operation. This structure is defined in the
/usr/include/sys/devinfo.h file. The SCSI target-mode union is used for this as follows:
Initiator-Device
buf_size
Size of transmit buffer.
num_bufs
Number of transmit buffers
max_transfer
Unused. Set to zero.
adap_devno
Major or Minor devno of SSA adapter to be used for the next transmit
operation.
Use TM_GetDevinfoNodeNum( ) to read the node number to which the data is sent.
Target-Device
buf_size
Size of receive buffer.
num_bufs
Number of receive buffers
max_transfer
Unused. Set to zero.
adap_devno
Major or Minor devno of SSA adapter initially used by the paired initiator-mode
device.
