Solaris disk drivers need to support a minimum set of ioctl commands specific to Solaris disk drivers. These I/O controls are specified in the dkio(7) manual page. Disk I/O controls transfer disk information to or from the device driver. A Solaris disk device is one that is supported by disk utility commands such as format(1M) and newfs(1M). Table 11-1 lists the mandatory Sun disk I/O controls.
