1.2.0.1 SCSI Interface Mode
With the SCSI Interface mode, CHM motion is controlled by a SCSI driver that
allows the CHM to retrieve and replace cartridges as specified by the host
through the SCSI-2 command set.
Note – When you switch the tape library from SCSI Interface mode to another
mode, CHM operations are temporarily halted. However, tape drive operations
can still continue.
1.2.0.2 Sequential 1 Mode and Sequential 2 Mode
When the tape library is operating in the Sequential 1 mode, the CHM picks
cartridges from the removable cartridge holder sequentially and places them in
Drive 1 for processing. When the tape library is operating in the Sequential 2
mode, the CHM places cartridges in Drive 2 for processing.
1.2.0.3 Dual Sequential Mode
For tape libraries with two tape drives, dual sequential allows you to use the
top five tape cartridges in the removable cartridge holder in Drive 1 and the
bottom five tape cartridges in Drive 2.
1.2.0.4 LCD Interface Mode
When the tape library is operating in LCD Interface mode, the user can instruct
it to perform CHM motion commands, such as picking and placing cartridges,
and performing diagnostics, from the Operator Panel without communicating
across a SCSI bus.
You do not have to operate the tape library in LCD Interface mode to use most
of the features available through the LCD. For example, you can use the LCD
to check system statistics when it is operating in any of the control modes.
Note – LCD Interface mode is required only when you want to control the
motions of the CHM through the Operator Panel.
