Setup guide

10 Once the initialization process completes, create a back-up of the storage
configuration by typing:
./XR_config.pl --saveConfig
A back-up of the storage configuration is saved.
To configure arrays with two XR enclosures:
1 Open a terminal and log in as root.
2 Make sure only one set of enclosures is connected to the workstation.
3 Go to the /usr/discreet/DKU/current/Utils/Storage/current/ directory, and
run the XR Configuration Utility by typing:
./XR_config.pl
The script displays information on the storage, such as: enclosure type,
RAID controller firmware version, number of enclosures, number of
loops.
4 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.
5 After the utility detects the number of enclosures and drives, it presents
you with a list of options.
6 Type 2 and press Enter.
This option instructs the configuration utility 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.
7 When asked if you have a 2-loop or a 4-loop configuration, select the
option that applies to your storage. Note that 4-loop configurations are
only supported for XR 6412 and XR 6500 series storage.
The utility creates LUNs on your storage. This process might take a few
minutes.
When the LUN creation process completes, the configuration utility asks
you if you want to create the XFS filesystem on the storage array.
8 Type N.
NOTE If you answered Y by mistake (the dealt answer), you get another
chance to answer no after the system rescans the disks. It is very important
that you do not create the filesystem at this point.
9 Type x to exit the configuration utility.
