13 Auditing the Library

An audit verifies cartridge locations and updates the library database, which contains the volume ID, current location, and verified status for each cartridge.

The library automatically performs an audit after an access door closes or after the library initializes.

Note:

Initiating an audit from SLC only updates the library database. To update the host database, you must initiate an audit from the host.

Performing a Physical Audit of the Entire Library

Note:

You cannot stop a physical audit after it begins.

For an entire library audit, the robot visits all slots (storage, CAP, drive, reserved), updates the cartridge database, and changes the "verified" status of a cartridge to true.

Although the audit is a background process, it does require sharing of robot resources. Do not run this audit during peak activity periods. The audit takes approximately 0.5 seconds per cartridge slot.

  2. Select the Library on the device tree.

  3. Click the Audit tab.

Performing a Verified Audit of a Range of Cells

A verified audit validates the status of a cartridge location in the cartridge database. If a cartridge address has a verified status of false, the library does a physical audit of that location and updates the cartridge database.

  1. In SLC, select Tools > Diagnostics.

  2. Select the Library in the device tree.

  3. Click the Audit tab.

  4. Select Yes for Verified Audit (select No for Entire Library and Physical Audit).

  5. From the drop-down lists, select the internal address for the starting and ending locations of the audit.

Meaning of the Audit Indicator

To indicate an audit is in progress, SLC displays a spinning indicator and the message "Audit in progress". When you see this indicator, do not open the library access door. This will cause the audit to restart.

The audit indicator only displays when an audit is initiated automatically (library access door has been opened and closed, library power up, or restart). The indicator does not display for audits initiated from SLC or the host.
