Service Access

Enable service access

This selection provides the ability to access the library managers through a modem connection, if installed. This will also allow ®les (log and dump) to be off-loaded from the library manager by service personnel. The library manager may prompt the operator for the administrator password.

SNMP Options

The 3494 can be attached to many different host systems, with various operating systems that communicate with the library using different types of connections. During operation, the 3494 may encounter situations that the user would want to know about, such as a door being opened (which causes the library to stop). Because there are many different attachment methods, the 3494 provides a standard TCP/IP protocol called Simple Network Management Protocol (SNMP) to send alerts (called SNMP traps) over a TCP/IP LAN network to one or more SNMP monitoring stations. These monitoring stations, along with other customer-supplied software, can be used to alert operations staff of possible problems or operator interventions that occur at the library. Figure 134 shows a basic SNMP block diagram.

With this method, the 3494 can be monitored at one or more locations, along with other equipment (both IBM and non-IBM) that also supports the SNMP protocol. Monitoring is independent of the host system that is controlling the equipment and independent of the location of the 3494s.

The Library Manager now contains limited SNMP (Simple Network Management Protocol) support. This section discusses how to use the Library Manager's SNMP features.

The Library Manager generates SNMP trap messages to inform network monitoring stations that certain events have occurred on the 3494 Tape Dataserver. The Library Manager code does not contain any SNMP Management Information Base (MIB) support.
