IOCINFO (Device Information) SSA Disk Device Driver ioctl Operation
Purpose
To return a structure that is defined in the /usr/include/sys/devinfo.h file.
Description
The IOCINFO operation returns a structure that is defined in the
/usr/include/sys/devinfo.h header file. The caller supplies the address to an area of
type struct devinfo in the arg parameter to the IOCINFO operation. The device-type
field for this component is DD_SCDISK; the subtype is DS_PV. The information that is
returned includes the block size in bytes and the total number of blocks on the disk
drive.
