Test the Library Connection

Test the connection between STA and each library. For SNMP, this test is required. For SCI, it is highly recommended.

To avoid dropped connections and lost library data, you should perform this procedure for each monitored library whenever you add or change connection settings for the library or the STA client.

1. Review When to Test the Library Connection. Because a connection test can cause a momentary loss of incoming library data, you should perform this procedure only when necessary.
2. In the STA GUI, expand the Setup & Administration tab, and then select Library Connections.
3. In the Monitored Libraries table, select a library, then click Check / Test Connection .
   
4. The Connection Test Status message displays the results. Click OK to dismiss.

   For SNMP, the message indicates results for the following:

   • MIB Walk Channel test—Checks for library initialization, network connectivity, proper SNMP client settings, and correct library firmware.
   • Trap Channel test—Requests that the library send a test trap (13) to STA.
   • Media Validation Support test—Checks for the minimum library firmware and configuration required to support STA media validation.

   For SCI, the message indicates results for the following:

   • STA-to-Library Communications—Results of the SCI connectivity from STA to the SL4000 library.
   • Library-to-STA Communications—Results of the outbound SCI connectivity from the SL4000 to the STA server.
5. The Monitored Libraries table updates with the results of the test. See About the Monitored Libraries Table for a description of the fields.
6. If the test fails:
   • If the test fails because of a timeout, repeat this procedure during a period of lower library activity. Once the test completes, you can compare the timestamps to verify that the library is providing current information.
   • If the OSCI test fails, see Enable and Test the SCI Destination on the SL4000.
   • If the test fails for other reasons, see Troubleshoot the Library Connection.
7. After successfully testing the connection, proceed to Manually Collect Library Data.

When to Test the Library Connection

You should perform a connection test at specific times to ensure STA can receive library data.

• After initial configuration of the connection between STA and a library. For SNMP, the test is required to populate the engine ID. For SCI, the test following initial configuration is highly recommended.
• After modifying any settings for the STA client or a monitored library.
• After rebooting a monitored library. Wait until the library is fully operational before initiating the connection test.
• After a redundant electronics switch has taken place on a SL3000 or SL8500 library. Wait until the switch has completed and the library is fully operational before initiating the connection test. See Update SNMP After a Redundant Electronics Switch (SL3000, SL8500).
• Anytime you suspect loss of data from one or more libraries.
