<h1 class="topictitle1">Example: Initialize optical volumes</h1>
|
|
<div><p>This example provides information about initializing optical volumes
|
|
in an optical media library.</p>
|
|
<p>If the cartridge you added was a new cartridge, you will see something
|
|
similar to the display shown below. This indicates that the optical cartridge
|
|
has two uninitialized volumes on it.<br /><div class="imageleft"><img src="rzam4024.gif" alt="Work with Optical Volumes" /></div><br /></p>
|
|
<p>An uninitialized volume is an optical volume that has never been formatted
|
|
or initialized. It is similar to a new diskette that needs to be formatted.
|
|
If a volume has not been initialized, it has a volume type of *UNFORMATTED
|
|
(uninitialized).</p>
|
|
<p>An uninitialized volume does not have a volume name written to it. When
|
|
an uninitialized volume is added to an optical media library, a volume name
|
|
that consists of a date and time (YYMMDDHHMMSS) is assigned to it. Optical
|
|
volumes cannot be written to or read from until they are initialized. </p>
|
|
<p>On the Work with Optical Volumes display, you see that two volumes were
|
|
added, one for each side of the optical disk cartridge. If either of the volumes
|
|
was initialized, the volume type would indicate *PRIMARY or *BACKUP, and most
|
|
likely the volume ID would be different from the ones in the example. An optical
|
|
disk can contain one volume that is initialized and one volume that is uninitialized.
|
|
The volumes are treated independently even though they exist on the same cartridge.</p>
|
|
<p>If both volumes are uninitialized, the earlier date and time for the volume
|
|
names indicate the volume that was facing up in the input/output station.
|
|
In this example, because side A was facing up when the add operation was performed,
|
|
we know that 941215111729 is side A. This is important to know so the volume
|
|
can be properly labeled when removed from the library.</p>
|
|
<p>To initialize the volume you determined to be side A, enter option 10 (Initialize)
|
|
in the Opt field beside that volume. Press the Enter key. </p>
|
|
<div class="note"><span class="notetitle">Note:</span> Initializing a previously initialized volume makes all existing data
|
|
on that volume inaccessible. If you typed 10 next to a volume that is already
|
|
initialized and you do not want to lose the data on that volume, do not continue
|
|
with this function. Use a volume that is uninitialized.</div>
|
|
<p>Complete the following fields on the Initialize Optical Volume display:</p>
|
|
<dl><dt class="dlterm">Volume identifier</dt>
|
|
<dd>This is the existing volume ID of the volume that you are going to initialize.
|
|
For uninitialized volumes, this name is a system-generated name that consists
|
|
of the date and time. This is only a temporary name until the volume initializes.</dd>
|
|
</dl>
|
|
<dl><dt class="dlterm">New volume identifier</dt>
|
|
<dd>Type the new name for the specified volume. This is the name that users
|
|
and applications will use when referring to the volume.</dd>
|
|
</dl>
|
|
<dl><dt class="dlterm">Volume-full threshold</dt>
|
|
<dd>Leave this set to the default value. Use this value to give the volume
|
|
a logical volume-full threshold.</dd>
|
|
</dl>
|
|
<dl><dt class="dlterm">Check for active volume</dt>
|
|
<dd>Leave this set to *YES to verify that the optical volume was previously
|
|
initialized.</dd>
|
|
</dl>
|
|
<dl><dt class="dlterm">Clear</dt>
|
|
<dd>Leave this set to *NO. This specifies whether or not existing data on
|
|
the volume will be cleared during the initiating process. This parameter only
|
|
applies when the volume media type is *DVD-RAM. Specifying CLEAR(*YES) can
|
|
cause this operation to take up to one hour.</dd>
|
|
</dl>
|
|
<dl><dt class="dlterm">Text description</dt>
|
|
<dd>Enter a short description of the volume. Fifty characters are available
|
|
for this field. </dd>
|
|
<dd class="ddexpand">Press the Enter key to initialize the volume.</dd>
|
|
</dl>
|
|
<div class="note"><span class="notetitle">Note:</span> Initializing an erasable optical volume can take up to 30 minutes.</div>
|
|
<p>After the volume is initialized, the Work with Optical Volumes display
|
|
reappears and the previously uninitialized volume is now initialized. The
|
|
type has changed from *UNFORMATTED to *PRIMARY, and the volume is now available
|
|
for reading and writing files and directories</p>
|
|
<p>From this display, you can select the following options:</p>
|
|
<ul><li><strong>1</strong> - Add an optical cartridge</li>
|
|
<li><strong>2</strong> - Change the volume attributes</li>
|
|
<li><strong>3</strong> - Copy a volume</li>
|
|
<li><strong>4</strong> - Remove an optical cartridge</li>
|
|
<li><strong>5</strong> - Display volume information</li>
|
|
<li><strong>6</strong> - Print volume information</li>
|
|
<li><strong>7</strong> - Rename a volume</li>
|
|
<li><strong>8</strong> - Work with directories on the volume</li>
|
|
<li><strong>9</strong> - Delete volume information for a previously removed volume</li>
|
|
<li><strong>10</strong> - Initialize or reinitialize a volume</li>
|
|
<li><strong>11</strong> - Work with directories and files on the volume</li>
|
|
<li><strong>12</strong> - Duplicate a volume to another optical media</li>
|
|
<li><strong>13</strong> - Check the volume for damaged files and return a count of the
|
|
directories and files</li>
