Setup guide

4 Create LUNs. If you have more than one XR enclosure, create all of the LUNs individually, then create
the XFS file system on them all at once.
5 Create the XFS filesystem
Configure Dot Hill storage
1 Ensure the storage enclosures are connected to the workstation as documented. Connect an Ethernet
cable to the Ethernet port of the top storage controller (controller A) and to an available network port
on the workstation.
2 Configure your workstation's eth port to the same subnet as the storage controller. The default IP
address of storage controller A is 10.0.0.2.
3 In a terminal, as root, run DH_config.sh.
4 Enter the IP or hostname of the top controller of the storage enclosure.
WARNING If your storage is connected to the network switch rather than directly to the workstation, make
sure you are entering the correct IP address or hostname at this step. Entering the information of another
storage enclosure will lead to loss of data on that storage.
5 The main menu is displayed. Select option 2 to partition the storage, create the XFS filesystem and
mount it. Confirm whether you want to delete event logs from the storage.
6 Select the number of loops to configure: 2 or 4.
7 If the script detects a previous configuration on the storage, it will ask you whether you want to keep
it. Answer No if you want to start with a fresh configuration.
8 The script partitions the storage, creates the XFS filesystem and the mount point and then mounts the
storage. When the operation completes you are returned to the main menu. Type 6 to exit the
configuration utility.
After configuration, the storage spends a few hours initializing. During this time, performance is not optimal.
You can monitor the status of the drives by logging into the RAIDar Storage Management utility.
1 In a web browser enter the IP address of the top storage controller, for example: http://10.0.0.2.
2 Log in. The default username is "manage" and the default password is "!manage"
3 Click on each of the Vdisks. The Current Job row in the table indicates the progress of the initialization
operation.
Configure XR storage
Create LUNs
1 In a terminal, as root, run /usr/discreet/DKU/current/Utils/Storage/XR/XR_config.pl.
The XR Configuration Utility exits without configuring your storage if any of the following is true:
■ The total number of disks is not a multiple of 12.
■ One of more of the enclosures does not have the correct firmware.
■ When using two sets of enclosures, the number of expansion chassis attached to each XR RAID
enclosure is not the same.
■ An odd number of enclosures in a 4-loop configuration. Only even numbers of enclosures are
supported.
2 The script displays information about the storage, and if a LUN configuration already exists on the
storage, you are prompted for confirmation to overwrite that configuration.
