12.2 Connecting a Divar

The following hardware is required to connect a Divar:

• To connect a Divar with the first subsystem you need the DVA-ACON-HD50A SCSI cable.

• To expand an existing system (Divar and subsystem) with an additional subsystem, you

must order the DVA-ACON-VD680A (0.5 m/20 in.) SCSI cable.

To connect the Divar:

1. Connect the Divar with the subsystem. You must switch the Divar and the subsystem off.

Take care of proper connection and tighten the screws of the plug.

Fig. 12.2 Connecting Divar

2. For daisy chaining several subsystems, you must switch off the termination of channel

CH0/1-OUT of all subsystems except the last.

Expand the configuration tree -> click Configuration -> Channel -> Channel 0 or

Channel 1 -> ID Tab -> Termination: Disabled -> Apply.

3. Click Configuration -> Configuration Parameters -> System tab -> Reset the Controller -

> Apply. The subsystem is reset.

4. For daisy chaining, change the CH0/1-OUT SCSI channel ID of the second subsystem.

Expand the configuration tree -> click Configuration -> Channel -> Channel 0 or

Channel 1 -> Parameters Tab -> for DVA-08K: clear the 0 and 1 check boxes and select

the 2 and 3 check boxes -> Apply.

5. Click Configuration -> Configuration Parameters -> System tab -> Reset the Controller -

> Apply. The subsystem is reset.

6. Click Configuration -> Host LUN Mapping and change to new ID.

7. Switch on the subsystem and then the Divar. The power switches of the subsystem are

located on the rear side of the unit.

To configure the Divar:

(Use the control elements on the front panel)

NOTICE!

• Two subsystems: Make the SCSI connection after you have changed the SCSI ID of the

second subsystem.

• Due to SCSI specifications, do not daisy chain more than two subsystems.

CAUTION!

• The internal disks of a Divar must be disabled when using a disk array in RAID mode. Oth-

erwise if the internal disk of Divar fails, all data is lost (even on the subsystem).
