2 Go to the directory /usr/discreet/DKU/current/Utils/Storage/current/, and

run the XR Configuration Utility by typing:

./XR_config.pl

The utility detects whether a LUN configuration exists on the storage

attached to that workstation.

3 If a LUN configuration already exists on the storage, you are prompted

for confirmation to overwrite that configuration.

WARNING LUN configuration is destructive. Make sure you want to overwrite

an existing configuration before you confirm.

4 After the script detects the number of enclosures and drives, it prompts

you to indicate the filesystem your storage uses.

5 When asked if you have a 2-loop or a 4-loop configuration, select the

option that applies to your storage.

The XR Configuration Utility configures your storage.

6 Type x to exit the XR Configuration Utility.

7 Reboot your workstation, so that the newly-created LUNs are rescanned

by the operating system.

Note that the XR Configuration Utility exits without configuring your storage

if any of the following issues are detected:

■ An incorrect number of disks. The total number of disks must be a multiple

of 12.

■ One or more of the enclosures do not have the correct firmware.

■ In a dual RAID enclosure environment, the number of expansion chassis

on each RAID enclosure is not the same.

■ An odd number of enclosures in a 4-loop configuration. Only even numbers

of enclosures are supported.

Partitioning Disks or LUN devices as Primary

Partitions

To achieve optimal performance, each disk or LUN in the array should be

partitioned as a single primary partition.
