The Library Manager code offers the ability to monitor the following Library Manager
events:
v OPINT - Operator Interventions
v UNSOL - Unsolicited Attention Messages
v SERVC - Service Request Messages (not currently supported)
v CHCK1 - Library Manager Check1 Conditions
v TESTM - Test SNMP Trap Message
OPINT Events
OPINT events inform the monitoring station of the state of the 3494. They
can inform the monitor station that the 3494 has developed problems, and
can even request service calls. All OPINT messages are located in the
OPINT message table. See Table 7 on page 216.
OPINT traps are the best way to monitor the 3494, and these Library
Manager trap types should be selected at all times.
UNSOL Events
UNSOL events offer additional support to the OPINT messages. They are
not as helpful as the OPINT message, but they can be used to track drive
availability, volume movement, etc.
In order to receive UNSOL messages, the 3494 must be online, and it must
have at least one host. All UNSOL messages are located in the UNSOL
message section. See “UNSOL Library Manager SNMP Traps” on
page 221.
CHCK1 Events
CHCK1 events are posted when the Library Manager code encounters
problems that require reinitializing the Library Manager.
TESTM Events
TESTM events are automatically generated by the Library Manager to test
the ability to send SNMP trap messages. They are intended to verify the
ability to send traps to the monitor station.
Using the Library Manager’s SNMP Features
Selecting SNMP Trap Types
First, select which type of Library Manager trap events need to be monitored. To do
this, select Commands from the Main Menu, and select SNMP options. Then
select the Select SNMP trap types sub-menu item. A dialog box with all the Library
Manager trap types is displayed (See Figure 135 on page 210). Select the Library
Manager trap types that need to be monitored. When done, select OK.
