Partitioning the Storage and Creating the XFS
Filesystem
Before you can use a new storage array, you need to create logical units (LUNs)
on it, partition them, group the partitions into a logical volume, and then
create the XFS filesystem on the logical volume.
All these operations can be easily performed using version 1.5 of the XR
Configuration Utility from Autodesk. This version of the XR Configuration Utility
is available in versions 4.5.1 and newer of the Discreet Kernel Utilities (DKU).
If your workstation is using an older version of the DKU that does not have
the latest XR Configuration Utility, or if you prefer to manually partition your
storage array and configure the filesystem, refer to Overview (page 184).
Perform one of the following procedures to configure your storage using the
XR Configuration Utility. The procedures are different for storage arrays with a
single set of enclosure, and for arrays with two sets of enclosures.
Note that the XR Configuration Utility exits without configuring your storage
if any of the following issues are detected:
The total number of disks is not a multiple of 12.
One of more of the enclosures do 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.
To configure arrays with a single set of enclosure:
1 Open a terminal and log in as root.
2 Go to the /usr/discreet/DKU/current/Utils/Storage/XR/ 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.
3 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.
