Setup guide

WARNING LUN setup destroys data on the device.
3 The utility detects the number of enclosures and drives and presents you with a list of options. Choose
2 to create LUNs with a sector size of 512 bytes. This is the optimal sector size for XFS DAS
(direct-attached) storage of Creative Finishing applications.
4 Choose 2-loop or 4-loop configuration. 4-loop configurations are only supported for XR 6412 and XR
6500 storage. The utility creates LUNs on your storage. This process might take a few minutes.
5 When the LUN creation process completes, you are prompted to create the XFS filesystem.
■ If configuring arrays with two XR enclosures, type N . If you answer Y (the default) by mistake, you
get another chance to answer no after the system rescans the disks. Do not create the filesystem
until you have create LUNs on all enclosures.
■ If you have only one XR enclosure choose Y to create the XFS filesystem,
Create the XFS filesystem
1 After choosing Y, and type Yes to confirm the detected devices. 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 to /mnt/StorageMedia on an HP Z800, or /mnt/stoneMedia on older
workstations. If the storage driver does not reinitialize quickly enough after LUN creation, the filesystem
creation step may fail, and the XR Configuration Utility posts an error like: "Can't open /dev/sdb1
exclusively. Mounted filesystem?" The filesystem will appear mounted. Type pvdisplay -v in the terminal
to verify that the physical volume, volume group and logical volume were created.
2 Exit the configuration script with x.
3 Even though your storage array is usable at this point, the drives are still initializing following the LUN
creation. Your storage operates at reduced performance until the initialization process completes. This
might take a few hours. To check the progress of the initialization run the command
/usr/discreet/DKU/current/Utils/Storage/XR_config.pl --arrayStatus
4 Once the initialization process completes, create a back-up of the storage configuration with the
command: /usr/discreet/DKU/current/Utils/Storage/XR_config.pl --saveConfig.
Arrays with two enclosures
1 After creating the LUNs on the first set of enclosures, power off the workstation, disconnect the storage
enclosures, and connect the second set of enclosures, then power the workstation back on.
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.
