TS3400 Tape Library Maintenance Information
microcode represents microinstructions used in a
product as an alternative to hard-wired circuitry to
implement certain functions of a processor or other
system component.
MIM . Media information message.
mixed scratch pool . An environment where the
customer will be using cartridges that might have been
written on with either an E06 or an E05 drive. The 3592
drive microcode will ensure that an E06 cartridge format
and any E06 encrypted cartridge format can be
recognized by an E05 drive (regardless of whether it is
encryption enabled or not).
mm . Millimeter.
modifier . That which changes the meaning.
mount a device . To assign an I/O device with a request
to the operator.
MP . Microprocessor.
ms . Millisecond.
MSG . Message.
multipath . Pertaining to using more than one path.
N
N/A . Not applicable.
node . In a network, a point at which one or more
functional units connect channels or data circuits.
NTP . Network Time Protocol. This allows the library to
set its internal date and time based on the date and time
of a sever.
NVS . Nonvolatile storage. A storage device whose
contents are not lost when power is cut off.
O
oersted . The unit of magnetic field strength in the
centimeter-gram-second (cgs) electromagnetic system.
The oersted is the magnetic field strength in the interior
of an elongated, uniformly wound solenoid that is
excited with a linear current density in its winding of
one abampere per 4
π
centimeters of axial length.
offline . Pertaining to the operation of a functional unit
without the continual control of a computer. Contrast
with
online .
online . Pertaining to the operation of a functional unit
that is under the continual control of a computer.
Contrast with
offline .
OPER . Operation.
ov . Over voltage.
overrun . Loss of data because a receiving device is
unable to accept data at the rate it is transmitted.
overtightening . To tighten too much.
P
parameter . A variable that is given a constant value for
a specified application and that may denote the
application.
p bit . Parity bit.
PC . Parity check.
PCC . Power control compartment.
PDF . Portable Document Format.
PE . Parity error. Product engineer.
PFS . Perfect forward secrecy.
pick . Pertaining to the library, to remove, by means of
a robotic device, a tape cartridge from a storage slot or
drive.
picker . A robotic mechanism located inside the library
that moves cartridges between the cartridge storage slots
and the drive.
PM . Preventive maintenance.
POR . Power-on reset.
port . A physical connection for communication
between the 3590 and the host processor. The 3590 has
two SCSI ports.
Portable Document Format (PDF) . A standard
specified by Adobe Systems, Incorporated, for the
electronic distribution of documents. PDF files are
compact, can be distributed globally (via e-mail, the
Web, intranets, or CD-ROM), and can be viewed with the
Acrobat Reader, which is software from Adobe Systems
that can be downloaded at no cost from the Adobe
Systems home page.
Private key . A cryptographic key used to decrypt a
message.
PROM . Programmable read only memory.
PS . Power supply.
PWR . Power.
