with customer-supplied software) can alert operations personnel of possible problems or operator
interventions that occur.
All of the automation products support SNMP (Simple Network Management Protocol) and all of them
support SNMP read and walk capability.
The new Conguration capability of SNMP Query provides a common Management Information Base
(MIB) across all of the tape libraries. This capability allows a product administrator to audit the settings of
all of their tape libraries to ensure that they comply with their own policies.
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.
• Product Identication such as product name, description, manufacturer, model number, rmware
level, and the URL that the trap is designated for.
• Product Status such as the severity of the trap, status (current and previous) and the time the trap
occurred.
• Library State (physical device status) such as identication 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.
• Drive Status such as the identication of each drive in the library, rmware level, serial number, and
other address and status information.
• Trap Denitions 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.
• SNMP MIBs The library's MIB contains units of information that specically describe an aspect of the
system, such as the system name, hardware number, or communications conguration. When with
SNMP to monitor your TL1000 Tape Autoloader, make sure that the TL1000 MIB le is loaded on your
SNMP monitoring station. SNMP traps are sent to the SNMP monitoring stations that are dened for
your library (see “Conguring trap notications” on page 39
).
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.
LTO tape drives
The TL1000 Tape Autoloader supports the and later half height tape drives.
The LTO 3 and later half height tape drives support the Serial Attached SCSI (SAS) interface. They have
one Mini-SAS (SFF-8088) connector.
