Changing the SCSI address — parallel SCSI devices (Configuration > Change Drive)
CAUTION:
If you change the SCSI ID, you might need to cycle power on the host server and reconfigure your
backup software before you can use the device.
This option changes the SCSI address of the tape drive. The tape drive uses logical unit number (LUN)
0. The SCSI address for the Autoloader will always be the same as the tape drive but will use LUN
1. Access to this feature requires the administrator password.
To change the drive SCSI address:
1. From the Home screen, press Previous or Next until the screen displays Configuration . Press Enter
to select.
2. Press Previous or Next until the screen displays Change Drive . Press Enter to select.
3. Enter the administrator password if prompted.
4. The screen displays the current SCSI ID. Press Previous or Next to change the SCSI ID number.
Press Enter to select. An example of the screen display is Drive SCSI ID 6 .
Setting behaviors (Configuration > Autoloader Behavior)
The supports three behavior modes: Random, Sequential, and Automatic. The Autoloader automatically
detects the required mode from the series of SCSI commands it receives; however, you can also
change the mode. Choose the operating mode based on the capabilities of the software controlling
the tape cartridges. Access to this feature requires the administrator password.
Random mode : In Random mode, the device does not automatically load tapes into the tape drive;
it waits for commands from the software or operator to load and unload tapes. Random mode is used
with a full featured or a robotics-aware backup application and is the most common mode of operation.
Your backup software must support robotics, which may require an additional software module.
Sequential mode : In Sequential mode, the device automatically loads and unloads tapes from the
drive. Sequential mode is used when the backup software is NOT robotics-aware or was designed
for standalone drives only.
The operator begins the sequence by loading the desired tape into the tape drive. When a tape is
unloaded for any reason, the device automatically removes the tape from the drive, returns it to its
original slot, then loads the tape from the next available higher numbered slot.
To further determine how you want tapes loaded into the tape drive while in Sequential mode, you
can set the
Loop and Autoload options.
• When Autoload mode is set, the device automatically loads the cartridge from the lowest-numbered
full slot into the tape drive. It then follows standard sequential operation. After configuring Autoload
mode, you must do one of the following for Autoload mode to take effect:
• Power cycle the device from the front panel.
• Reboot the device from the RMI Support: Reboot screen.
• Move the lowest-numbered cartridge to the drive before starting the backup application. If the
mailslot is enabled, the lowest cartridge location will be in the mailslot.
• When Loop mode is on, the original first cartridge in the sequence is reloaded after the device
has cycled through all available cartridges. If Loop mode is off and the last cartridge has been
unloaded, the device stops loading cartridges until you load another manually.
