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.
Creating Hardware LUNs
LUNs, also referred to as Logical Units or Logical Drives, are groups of disk drives that are striped together
to provide optimal performance and RAID protection. Once configured, LUNs are seen by the Linux operating
system as if they were single disk drives.
For systems with two sets of enclosures, you have to configure one set at a time with the XR Configuration
Utility. Connect the first set of enclosures, and use the utility to configure it. When done, disconnect the
first set and connect the second set. When the second set of enclosures is configured, re-connect both sets.
To configure LUNs on XR-series storage:
1 Open a terminal and log in as root and run
/usr/discreet/DKU/current/Utils/Storage/current/XR_config.pl. The utility detects whether a
LUN configuration exists on the storage attached to that workstation.
2 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.
3 After the script detects the number of enclosures and drives, it prompts you to indicate the filesystem
your storage uses. Type 2.
