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.

NOTE Make sure you do not re-partition the system drive or any other disks that

you want to preserve as they are. Partitioning destroys all data on the disks.

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.

3 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.

4 Use the parted command to re-partition each disk device identified in

the previous step. Type:

/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. For example:

/sbin/parted -s -- /dev/sdb mklabel gpt mkpart primary 0 -1

5 Repeat the command 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.

3 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.

4 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
