For more information, refer to “5.11.1 Device - Set Operating
Mode
” on page 42.
1.4.1 Mode 1 —
RDX
8000 Tape Library:
As
of firmware version 1.2, the unit appears to the host application as an 8 slot library (autoloader, media changer)
containing one to three generic
LTO
tape drive(s). The application controls which cartridge is “inserted” into one of
the
available “tape drives”. This mode requires the use of a data management/backup applications which supports a
libr
ary (media changer) containing one to three tape drives.
Note that the
RDX
8000 unit is emulating the
LTO
tape format to the host application including the actual file
format
recorded on the
RDX
cartridge.
RDX
cartridges which are recorded in this mode are not write/read interchangeable
with
standard
RDX
docks.
Use
of this mode requires the user to pre-format the standard
RDX
media to the tape format mode. The
RDX
8000
unit
identifies the current cartridge format via the
OCP
and
RDX
8000 interfaces.
1.4.2 Mode 2 —
RDX
8000
JBOD
(default setting):
The
RDX
8000 unit appears to the host operating system as 8 individual
RDX
cartridge drives, each with their own
drive
letter.
Note that, depending on the host operating system, drive letters may only appear when an
RDX
cartridge is inserted
into
a
RDX
8000 slot. Removal of media via cartridge eject may
cause
the drive letter to disappear.
This mode may be used with Windows or Linux operating systems for standard disk operations or with data
management/
backup application designed to operate with individual
RDX
storage units in a grouped
configuration.
