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
-
S
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
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)
