Viewing a device's cleaning properties

The Cleaning tab on the device properties provides statistics on totals and errors since the last cleaning. The documentation included with your device should list the acceptable limits for hard and soft errors; if not, check with the hardware manufacturer.

For robotic library drives, the statistics on the Cleaning tab are automatically updated when a cleaning job successfully completes. (Cleaning jobs can only be created for a robotic library drive.) If you want to maintain accurate cleaning statistics for your stand-alone drives, you can reset the cleaning statistics after the drive has been manually cleaned.

To view a device's cleaning properties

  1. On the navigation bar, click Devices.

  2. Expand the server icon, click Stand-alone Drives, or if the drive is attached to a robotic library, click Robotic Libraries.

  3. Select the device for which you want to view properties.

  4. Under General Tasks in the task pane, select Properties, and then on the Drive Properties dialog box, click Cleaning.

    The Cleaning tab provides the following information:

    Last cleaning date

    Last date a cleaning operation was performed on the device.

    Hours since last cleaning

    Number of hours that the device has been in use since the last cleaning.

    Reset Cleaning Statistics

    Click this to reset all cleaning statistics to zero (stand-alone drives only).

    Bytes written

    Number of bytes that have been written by this device since the last cleaning.

    Bytes read

    Number of bytes that have been read by this device since the last cleaning.

    Total mounts

    Number of times media has been mounted by this device since the last cleaning.

    Total seeks

    Total number of seek operations (performed when a specific piece of information is being located) that have been performed by this device since the last cleaning.

    Hours in use

    Total number of hours that this device has been in use (performing read, write, mount, and seek operations) since the last cleaning.

    Seek errors

    Number of errors encountered since the last cleaning while trying to locate data.

    Soft read errors

    Number of recoverable read errors encountered since the last cleaning. Soft errors may indicate the beginning of a problem. If excessive errors are reported for your environment, check the device and perform maintenance on it, and check the media for damage.

    Hard read errors

    Number of unrecoverable read errors encountered since the last cleaning. If you receive hard errors, check the device and perform maintenance on it, and check the media for damage.

    Soft write errors

    Number of recoverable write errors encountered since the last cleaning. Soft errors may indicate the beginning of a problem. If excessive errors are reported for your environment, check the device and perform maintenance on it, and check the media for damage.

    Hard write errors

    Number of unrecoverable write errors encountered since the last cleaning. If you receive hard errors, check the device and perform maintenance on it, and check the media for damage.
