Configuring Partitions and Storage Devices

In most deployments, the fifth step towards configuring a direct-attached

Memory Array system with a Linux host is to configure block device partitions.

Create block device partitions on the Memory Array for creating multiple file

system partitions. Use the

/dev/vtmsa device for creating file systems only if a

single large partition is required.

When creating partitions for 4kB partition alignment, the fdisk utility has an

option that lets you override the default geometry of 63 sectors per track. Use

fdisk with the -S56 option for 4kB alignment on created partitions. For more

information see Memory Array Flash 4kB Alignment on page 169.

Creating Block Device Partitions

To create a block device partition on the Memory Array:

1. Log into the host computer as root.

The following command is only needed when splitting the block device into

multiple partitions.

2. First, open the device for adding partitions by typing the following at the

command prompt:

Where

/dev/vtmsa specifies the device to open.

The information shown below is returned and you will be in the block device

setup menu.

fdisk /dev/vtmsa

# fdisk /dev/vtmsa

The number of cylinders for this disk is set to 16709.

There is nothing wrong with that, but this is larger

than 1024, and could in certain setups cause problems

with:

1) software that runs at boot time (e.g., old versions

of LILO)

2) booting and partitioning software from other OSs

(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):
