Unmounting a Tape or Disk

The Unmount command causes IRIS to rewind a tape and take the tape or optical disk drive off line. The log information is cleared from the screen. This command must be invoked before a new tape can be mounted.

  1. Select Commands > Unmount.
  2. Wait for the tape to completely rewind, then remove it from the tape drive.

    If the media is a DVD, the contents of the temporary buffer used for writing the DVD are flushed to the DVD, that is, you do not lose the data in the buffer.

    This may delay the unmounting step by 20 seconds. If you quit IRIS (qiris) without unmounting the DVD, the buffer is flushed in the same way (delaying the qiris).
