Configuring Storage Devices
The GX9000 is designed to operate with multiple storage devices in a variety
of configurations. Through the SCSI menu you can configure one drive to
mirror another, have two separate drives behave as one larger drive, or use
one drive to insure another. You can also control simple copy or backup
operations from this menu. More complex backup and file handling is
accessible from the GXR Remote Control Software.
The internal SCSI bus of the GX9000 can be connected to the two front panel
drive bays and is also accessible via a 68 way connector at the rear of the
unit. The bus is terminated at the onboard SCSI controller and should also be
terminated at the last SCSI device on the bus. If no external drive is
connected, the bus should be terminated using the inbuilt active SCSI
terminator. The rear panel DIP switch 9 next to the rear panel SCSI
connector allows the SCSI termination to be switched on and off as shown
below.
Primary Drive
On power up the GX9000 allocates a primary drive for all record and replay
operations. The unit scans the bus for available SCSI ID’s starting at 0 and
continuing through 15, although currently only ID’s in the range 0-6 should be
used for drives. The GX9000 automatically allocates the first available drive
as the primary drive. This drive can be either of the front panel mounted
drives or any external SCSI storage device.

The display shows all drives connected to the SCSI bus. Each character
position on the lower display represents one possible SCSI ID. ID 0 is the
leftmost character; ID 7 is the rightmost character. If a drive is detected,
its ID will be displayed in the relevant position. The currently active drive
is shown as a flashing character. The initiator ID is represented by the
character ‘I’. Normally the initiator has an ID of 7; in this case the
character ‘I’ will appear in the rightmost character of the lower display.
•
Use
the
Value Up
and
Value Down
buttons to select an alternative SCSI
device. Note that the cursor is shown as a blinking character which can
be confusing as the currently selected drive is also shown as a blinking
character. Occasionally you may have to use the
Value
buttons to move
the cursor over a dash (unavailable SCSI ID) to determine which ID is the
currently selected Primary Drive.
•
Press
the
Enter
button to log the new drive. The messages
‘Logging
Drive’
,
‘Reading Disk’ and ‘Drive Logged’
will be
displayed if the drive is selected successfully.
If you see the message
‘Drive In Use’
then the drive is already
allocated as either an Expansion, Insurance or Mirror Drive. You need to
deselect the drive from its current function before selecting it as a Primary
Drive.
