As shown in Figure 6-2, the Online Capacity pane displays a pie chart indicating the following information:

  • Storage Available (displayed in blue)

    The percentage of volume storage that is currently unused and available for LTFS-LE data storage. Place your mouse over this region of the chart to display the value in actual Terabytes (TB).

  • Storage Used (displayed in red)

    The percentage of volume storage that is currently used. Place your mouse over this region of the chart to display the value in actual Terabytes (TB).

By default, the chart displays volume information for ALL volumes in the LTFS-LE library, regardless of media type.

If you want to adjust the chart to display volume information for a specific media type, click the menu in the upper right corner of the panel and select one of the following media types:

  • LTO-6.4T (Oracle's StorageTek 6.4 Terabyte LTO cartridge)

  • T10000T2:

    • Oracle's StorageTek 5 Terabyte T10000 cartridge formatted with a T10000C tape drive

    • Oracle's StorageTek 8 Terabyte T10000 cartridge formatted with a T10000D tape drive

Monitoring Drive Availability

The following figure shows the Drive Availability pane included on the LTFS-LE Dashboard page:
