Buttons and Meta Data Control Panel
At the bottom of the Scan/Cleanup page, the following is displayed:
Scan/Cleanup is designed to run as a periodic job. However, buttons are provided to enable
you to control the virtual tape erase process.
Submit Use this button with the Erase column checkboxes in the Status table. You can
change that erasure status by selecting or clearing the checkbox and clicking Submit.
Reset Use this button to remove any user-defined (override) controls and revert to the
business rules.
Erase Now!
Use this button to erase the selected virtual tapes or schedule tapes for erasure
immediately.
Also, if the meta_control_panel parameter is set to YES, the Meta Data Control Panel is
displayed at the bottom of the page. This control panel enables you to read and write
metadata. Metadata is stored with the virtual tape but is not part of the data itself. Metadata
is used by VTS to retain an audit trail of information, including the following:
• Tape label information, such as the volume label
• When the virtual tape was created, written to, updated, mounted, unmounted, or erased
• If and when the virtual tape was exported, imported, migrated, or restored
• How long the virtual tape has been retained
Note It is highly recommended that you do not write metadata unless instructed to do so by
Support.
To use the metadata control panel, complete these steps:
1. Select a virtual tape from the Cartridge Name drop-down list.
2. Specify whether to read or write metadata from the virtual tape by selecting an option
from the Direction drop-down list.
3. From the Meta Data Option drop-down list, select the metadata to read or write.
4. If you are reading data, leave the Meta Data Date field blank. If you are writing data,
enter a time or date in the field. Enter the date in the following format: DDMonYY (for
example, 22Dec06). Enter the time using the 24-hour clock, such as 15:39 for 3:39PM.
5. Click the VTMeta button. If you are reading data, a date is displayed in the Meta Data
Date field. If you are writing data, the operation and specified time or date is written to
the virtual tape.
