DKIOCADDBAD

x86: This ioctl() forces the driver to re-examine the alternates slice and

rebuild the internalbad block map accordingly. It should be used

whenever the alternates slice is changed by any method other than the

addbadsec(1M) utility.

DKIOCEJECT This ioctl() requests the disk drive to eject its disk, if that drive supports

removable media.

DKIOCLOCK SPARC: This ioctl() requests the disk drive to lock the door, for those

devices with removable media.

DKIOCUNLOCK

SPARC: This ioctl() requests the disk drive to unlock the door, for those

devices with removable media.

DKIOCSTATE SPARC: This ioctl() blocks until the state of the drive, inserted or

ejected, is changed. The argument is a pointer to a dkio_state, enum,

whose possible enumerations are listed below. The initial value should

be either the last reported state of the drive, or DKIO_NONE. Upon

return, the enum pointed to by the argument is updated with the current

state of the drive.

enum dkio_state {

DKIO_NONE,/∗Return disk’s current state ∗/

DKIO_EJECTED,/∗Disk state is ’ejected’ ∗/

DKIO_INSERTED /∗ Disk state is ’inserted’ ∗/

};
