Goal

 To qualify the physical contents of the library (e.g. slot contents, drives etc)

Solution

Robot malfunction, user intervention, engineer activity etc can result in the physical contents of the library not matching the contents of the library as it is known to the SL8500 database. This (incorrect) information can in turn be passed on to host systems (e.g. ACSLS and HSC) performing their own audits and result in cartridge access problems. Under normal circumstances no library audit should ever be necessary as normal procedures (e.g. door opens) will perform their own audits. 

This solution is taken from the SL8500 User's Guide.

▼ Audit the Entire Library

This task can be performed at any of the following:
• Local operator panel
• Standalone SL Console
• Web-launched SL Console

During this audit, the robot visits all the storage cells, catalogs the vol-ids and locations, and updates the library controller database.
Note – Although this audit is a background process and does not interrupt library operations, it does require sharing of robot resources. Therefore, it is not recommended that you run this audit during peak activity periods.
Note – You cannot stop this audit after it has initiated. The audit takes approximately 1/2 second per cartridge slot.

1 .Select Tools > Diagnostics.
2. Click the Library folder on the navigation tree.
    The Library page appears.
3. Click the Audit tab.
4. The Audit page appears. In the Entire Library section, click the Yes radio button. Then click the Audit button in the upper right corner.
   A message appears.
5. Click OK to perform the audit as a background process or Cancel to cancel the audit.
    Note – After you click OK, you cannot stop the audit. It runs until completion.

▼ Audit a Range of Cells

This task can be performed at any of the following:
• Local operator panel
• Standalone SL Console
• Web-launched SL Console

During this audit, the robot visits only a specific range of storage cells (including the cap and drives) and updates the library controller database.

1. Select Tools > Diagnostics.
2. Click the Library folder on the navigation tree.
    The Library page appears.
3. Click the Audit tab.
    The Audit page appears.
4. In the Entire Library section, click the No radio button. In the Physical Audit section, select Yes. In the Verified Audit section, select No.
5. In the Start Address and End Address sections, select the device types you want to audit and the starting and ending library internal address locations.
6. Click the Audit button in the upper right corner.
    A message appears.
7. Click OK to perform the audit as a background process, or Cancel to cancel the audit.
    Note – After you click OK, you cannot stop the audit. It runs until completion.
The Audit Console section displays the progress of the audit.

▼ Perform a Verified Audit

This task can be performed at any of the following:
• Local operator panel
• Standalone SL Console
• Web-launched SL Console

A verified audit validates the status of a specific cartridge location or a range of locations (including CAPs and drives) in the library controller database. If a cartridge address has a verified status of “false,” the system performs a physical audit of that location and updates the library controller database.

1. Select Tools > Diagnostics.
2. Click the Library folder on the navigation tree.
3. The Library page appears.Click the Audit tab.
    The Audit page appears.
4. In the Entire Library section, select No. In the Physical Audit section, select No. In the Verified Audit section, select Yes.
5. In the Start Address and End Address sections, select the device types you want to audit and the starting and ending library internal address locations.
6. Click the Audit button in the upper right area of the page.
    The Audit Console section displays the progress of the audit.

N.B. If the SL8500 finds new cartridges that it did not previously know about you *must* run an audit from the controlling application (HSC or ACSLS) to ensure that the library db and application db are in sync.
