Managing Library SNMP Connections : STA and Redundant Electronics

STA and Redundant Electronics

Note – This topic applies to SL3000 and SL8500 libraries only.

STA is capable of maintaining SNMP connections with up to two library IP addresses at a time. This enables you to configure STA to support the Redundant Electronics feature on monitored libraries. Complete configuration instructions are provided in the STA Configuration Guide; see “Configuring the Libraries for STA” in that guide.

In short, the following IP address configuration is recommended to configure STA to support Redundant Electronics:

•
Primary library IP address – 2B port on the active controller card
•
Secondary library IP address – 2B port on the standby controller card

Using this configuration, in the event of a controller card switch, STA will maintain SNMP communications with the library through the port specified as the secondary library IP address. However, you must also take the following manual actions after the switch completes:

•
Perform a connection test and a data collection to verify the library SNMP connection and retrieve current library configuration data. See “Test a Library SNMP Connection” and “Perform a Manual Data Collection” for instructions.
•
If a controller card is replaced after the Redundant Electronics switch, the IP address configuration for the library will change, so you will need to re-enter the SNMP connection information. See “Change SNMP Connection Details for a Monitored Library” for instructions.
