Set Data Format
This setting enables you to 1) set the data format to Auto Selection, THZ01,
THZ02, DLT2000, DLT2000XT, DLT4000; or DLT7000; and 2) Auto
Selection, enable, disable data compression. Compression can not be enabled
when either THZ01 or THZ02 format is in use. This setting applies to the next
or currently loaded cartridge only. An unload command returns to the default.
This setting does not display the current format of the loaded tape. Use the
Show Status Menu for this purpose. The default for density and compression is
Auto Selection.
Set SCSI
This option enables you to 1) enable or disable the library robotics SCSI bus
parity checking, and 2) set the SCSI addresses of the drives and the library
robotics. The defaults are: parity on, DLT 0 address = 4, DLT 1 address = 5,
robotics address = 0.
Set Library Mode
This option enables you to set the library robotics operating mode to Random,
Sequential DLT0, Sequential DLT1, or Sequential Split. Random is the normal
operating mode which affords complete host control of the library robotics.
The Sequential modes are locally controlled modes. Sequential DLT0 begins
with any cartridge loaded into DLT0. The Base Module monitors the status of
DLT0, and when the cartridge is unloaded by the host, it loads the next
cartridge in magazine numerical order. This operation continues to cycle until
all of the cartridges have been loaded. Sequential DLT1 is the same, except
that the cartridges are loaded into DLT1. Sequential Split mode provides two
simultaneous sequential modes. Cartridges 0 through 4 are loaded sequentially
into DLT0; cartridges 5 through 9 are loaded sequentially into DLT1.
