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.
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.
– The DVA-08E does not support daisy chaining.
– Do not assign drives bigger than 2 TB to Divar. In the factory default settings all disk
arrays are configured with logical drives (LD) smaller than 2TB.
– You may assign SCSI IDs from 0 to 6. If you use the internal DVD writer option, the SCSI
ID 5 is reserved for the DVD drive. Always use LUN 0 otherwise Divar will not discover the
drive.
CAUTION!
The internal disks of Divar must be disabled when using a disk array in Raid 5 mode.
Otherwise if an internal disk fails, all data is lost (even on the subsystem).

2. For daisy chaining several subsystems, you must switch off the SCSI channel's
termination of the used SCSI channel 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 SCSI channel IDs 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.
