Setup guide

4 When asked if you have a 2-loop or a 4-loop configuration, select the option that applies to your
storage. The XR Configuration Utility configures your storage.
5 Type x to exit the XR Configuration Utility.
6 Reboot your workstation, so that the newly-created LUNs are rescanned by the operating system.
The XR Configuration Utility exits without configuring your storage if any of the following is detected:
■ An incorrect number of disks. The total number of disks must be a multiple of 12.
■ One or more of the enclosures do not have the correct firmware.
■ In a dual RAID enclosure environment, the number of expansion chassis on each RAID enclosure is not
the same.
■ An odd number of enclosures in a 4-loop configuration. Only even numbers of enclosures are supported.
Partitioning Disks or LUN devices as Primary Partitions
To achieve optimal performance, each disk or LUN in the array should be partitioned as a single primary
partition.
On storage arrays with 450 GB drives, use the parted utility to create GPT (GUID Partition Table) type
partitions. On arrays with smaller drives, use the fdisk utility to create Linux LVM type partitions.
To partition disk or LUN devices with 450 GB drives or larger:
1 Reboot your system to reload the fibre channel adapter drivers.
2 Open a terminal, and log in as root and view a list of disks or LUN devices detected by the operating
system, using the following command: fdisk -l | grep dev. Identify the disk or LUN devices that
are part of the storage array to be configured with a standard filesystem. These devices will be
re-partitioned.
3 Use the parted command to re-partition each disk device identified in the previous step: /sbin/parted
-s -- <disk name> mklabel gpt mkpart primary 0 -1 where <disk name> is the name of a disk device
identified in step 1, without a partition number, such as /dev/sdb.
4 Repeat for each disk.
To partition disk or LUN devices with drives smaller than 450 GB:
1 Reboot your system to reload the fibre channel adapter drivers.
2 Open a terminal, and log in as root and view a list of disks or LUN devices detected by the operating
system: fdisk -l | grep dev. Identify the disk or LUN devices that are part of the storage array to be
configured with a standard filesystem. These devices will be re-partitioned.
3 If you plan to configure a standard filesystem on a former Stone FS storage array, delete the volume
label and volume table on each LUN device that is part of the storage array. Type the following command
for each LUN device: dd if=/dev/zero of=<LUN device> count=4096 Where <LUN device> is the device
name of a LUN in your storage array, such as /dev/sdc.
WARNING When using the dd command, be very careful to not delete your system drive (usually /dev/sda)
or any other drive aside from the LUNs in your storage array.
4 Use fdisk to re-partition each disk device identified in the previous step: fdisk <disk name> where
<disk name> is a disk device name without a partition number, such as /dev/sdf. The fdisk utility starts,
checks the disk device, and then displays its prompt.
NOTE When fdisk starts, a warning about the number of disk cylinders may appear. You can disregard this
warning.
