4. From the operating system prompt, invoke the init_iris command appropriate for
your device.
Here are some examples:
$ ini t_iris_tape (for drive unit 1 tape)
$ init_iris_mo (for drive unit 1 disk)
$ init_iris_mo -u2 (specifies the 2nd drive unit)
$ init_iris_dvd -h (to get help on usage)
$ init_iris_lda -h (to get help on usage)
Be sure to type the underscore (_ ) characters as shown. The command name is
intentionally long so you cannot type it accidentally.
The "-u2" specifies the second drive if there is more than one.
The "-h" argument prints the usage options.
The unit is checked and you are prompted to confirm the initialization. The drive goes
through several initialization steps that are displayed on the screen. If you have
forgotten to write enable the tape, you get a write protect error when IRIS attempts to
write the header information. Write-enable the tape and retype the command.
At the end of the initialization, IRIS displays a unique tape number that is used in the
future to refer to the disk inventories maintained for the tape.
Write the name of the medium that IRIS assigns on the tape or disk
label. This lets others know that the tape or disk has been initialized.
CAUTION!
The tape name is based on the first 3 characters of the Site ID, the year, month, day and
a random number to make the tape unique.

Mounting a Tape or Disk
Use the Mount command to mount initialized media.
1. Make sure the medium is initialized.
See Initializing a Tape or Disk for Recording (page 276) .
2. Insert the tape or disk into the drive and set it on line.
See the manufacturer's documentation.
3. Choose Commands > Mount.
IRIS scans the medium to determine what kind of medium has been mounted, and checks
the system disk to see whether there is a corresponding tape log.
The Status field reports Scanning during the Mount operation.
IRIS reports its findings in the Filter Summary field as one of:
