•Click Auto Populate (FC only) to allow the DX3000/DX5000

controller to automatically assign virtual devices to ONLY the

Fibre Channel ports. The controller assigns a robot and partition

to each Fibre Channel port.

Example: A DX3000 has two potential Fibre Channel ports and a

DX5000 has four potential Fibre Channel ports. A system with 2

partitions would have a robot assigned to LUN 0 on FC 1 and FC

2 and all other devices within that partition assigned to

additional LUNs on that port.

•Click Add LUN to add additional rows or LUNs at the bottom of

the screen. The maximum number of LUNs is 256.

• Use the drop down boxes located under the port number to select

the devices mapped to that port. Do NOT assign the same device

to more than one port unless your backup application can

support multiple mappings of the same device to more than one

port.

Example: Assign the robot and tape drives 0 and 1 to Eth1. From

the host, only the robot and tape drive 0 and 1 are visible from

Eth1. Assign tape drive 2 and 3 to FC1. Only tape drive 2 and 3

are visible from FC1.

•Click Clear to clear all of the device mappings.

Please make note of the following device mapping restrictions:

• The maximum number of virtual devices (tape drives and virtual

disks) is 64 per system.

• The maximum number of virtual tape drives and virtual disks on a

Fibre Channel port is 32 per port.

• The maximum number of virtual tape drives on an Ethernet port is

64.

• The maximum number of virtual disks on an Ethernet port is 64.

When all of the virtual devices have been assigned to the appropriate

port, click

Apply to accept the port settings.

Note: Microsoft Windows has a known issue recognizing more

than eight LUNs on a single Fibre Channel port. See

Microsoft Knowledge Base Article 310072:

http://support.microsoft.com/default.aspx?scid=kb;en-us;310072

for information on reconfiguring Windows to overcome

this limitation.
