Simple Network Management Protocol (SNMP) messaging
Occasionally, the library might encounter a situation that you want to know about,
such as an open magazine or a fault that causes the library to stop. The library
provides a standard TCP/IP protocol called Simple Network Management Protocol
(SNMP) to send alerts about conditions (such as need for operator intervention)
over a TCP/IP LAN network to an SNMP monitoring station. These alerts are
called SNMP traps. With the information supplied in each SNMP trap, the
monitoring station (together with customer-supplied software) can alert operations
personnel of possible problems or operator interventions that occur.
SNMP traps
SNMP Traps are alerts or status messages that can be collected, monitored, and
used to proactively manage attached libraries with SNMP protocol with the SNMP
monitoring stations. In summary, each trap provides the following information:
v
Product Identification
such as product name, description, manufacturer, model
number, firmware level, and the URL that the trap is designated for.
v
Product Status
such as the severity of the trap, status (current and previous) and
the time the trap occurred.
v
Library State
(physical device status) such as identification and status of devices
that is monitored. It would include enclosure, power supply, controller,
magazine status, drive count, cartridge slot count, and I/O station count. Also
included would be certain library statistics, and where appropriate, the fault FSC
(fault symptom code) including the severity and description of that fault.
v
Drive Status
such as the identification of each drive in the library, firmware
level, serial number, and other address and status information.
v
Trap Definitions
such as library status change, open magazine, I/O accessed,
hard fault information, requests to clean the drive, excessive retries, and
returning to normal operations.
v
SNMP MIBs
: The library's Management Information Base (MIB) contains units
of information that specifically describe an aspect of the system, such as the
system name, hardware number, or communications configuration. When with
SNMP to monitor your TL1000 Tape Autoloader, make sure that the TL1000 MIB
file is loaded on your SNMP monitoring station. SNMP traps are sent to the
SNMP monitoring stations that are defined for your library (see “Configuring
SNMP trap notifications” on page 4-31).
Network Time Protocol
NTP is an Internet standard protocol that assures accurate synchronization of
computer clock times in a network of computers. Running as a continuous
background client program on a computer, NTP sends periodic time requests to a
server, obtaining server time stamps, and with them to adjust the client’s clock.
