Setup guide

2 Create the LUNs.
3 Power off the workstation again, connect both sets of enclosures to the workstation.
4 Power the workstation back on and Create the XFS filesystem.
To perform only the filesystem creation operations:
1 In a terminal, as root, run /usr/discreet/DKU/current/Utils/Storage/current/XR_config.pl
--createFS. The configuration utility partitions the storage array, groups the partitions into a logical
volume, creates the XFS filesystem on the volume, and mounts the volume. This is the same as running
the XR_config.pl with no parameter, and choosing option 4 from the main menu.
2 Type Yes to confirm.
3 Following LUN creation, drive initialization may take a few hours. The storage array is usable during
this time but operates at reduced performance. To check the progress of the initialization, run
/usr/discreet/DKU/current/Utils/Storage/XR_config.pl --arrayStatus
4 Once the initialization process completes, back up the storage configuration:
/usr/discreet/DKU/current/Utils/Storage/XR_config.pl --saveConfig.
How to power storage on or off
Power your system and storage up or down in the proper sequence. An incorrect power up sequence can
mean your system does not recognize all drives.
Power on a system:
1 Ensure your workstation is shut down.
2 Power up the XE expansion enclosures.
3 Power up the XR RAID controller enclosures.
4 Wait about 90 seconds for all the drives to spin up. Their lights are solid green when they are spun up.
5 Power on your workstation.
Power off a system:
1 Shut down your workstation.
2 Shut down the XR RAID controller enclosures.
3 Shutdown the XE expansion enclosures.
Manually configure media storage
Overview
This section provides advanced instructions for manually configuring a storage array. Normally, you do not
need to perform any of these tasks, as they are all automatically performed by the XR Configuration Utility.
This utility is installed with the DKU and automates the LUN creation process.
NOTE Make sure you do not re-partition the system drive or any other disks that you want to preserve as they
are. Partitioning destroys all data on the disks.
