To create Physical Volumes for Volume groups (LVM) , the disk need to be partitioned to LVM type ie. 'Linux LVM' type . In fdisk , this can done by choosing 8e when prompted for partition type.
Since it is easy to script (non-interactive), I use parted command rather than fdisk to create partitions
For creating standard partitions, I use the below 2 non-interactive steps in our scripts
Step1. Creating the partition table for the device
For gpt, I use
Step2. create a primary partition that starts after 1mb (to ensure proper alignement)
parted -s /dev/sda unit mib mkpart primary 1 100%
From the below link , I gathered that partition can be set to LVM type interactively using set [partition number] lvm on
But, how can I incorporate this into step2 (non-interactive) shown above ? How to create LVM Partition in Linux
Hi all!
Working on Oracle v8.1.7.0.0 with OS as Suse v8.0 Linux.
I had created LVM,linked raw devices to LVM as below:

Hello,
I have a RHEL system with two 500GB hard drives in RAID 1 (I think hardware, but not 100% certain - any way to tell?).
It looks like it was just set up in default configuration with a small boot partition and one huge partition for the rest, which composes a LVM volume.
I want... (1 Reply)

PARTED(8) GNU Parted Manual PARTED(8)NAME
GNU Parted - a partition manipulation program
SYNOPSIS
parted [options] [device [command [options...]...]]
DESCRIPTION
This manual page documents briefly the parted command. Complete documentation is distributed with the package in GNU Info format; see
below.
parted is a disk partitioning and partition resizing program. It allows you to create, destroy, resize, move and copy ext2, ext3, linux-
swap, FAT and FAT32 partitions. This is useful for creating space for new operating systems, reorganising disk usage, and copying data to
new hard disks.
OPTIONS -h, --help
displays a help message.
-i, --interactive
where necessary, prompts for user intervention.
-s, --script
never prompts for user intervention.
-v, --version
displays the version.
COMMANDS
[device]
The block device to partition.
[command [options]]
Specifies a command to parted. If no command is given, parted will give you a command prompt. Commands are:
check partition
does a simple check on partition.
cp [source-device] source dest
copies the source partition's filesystem on source-device (or the current device if no other device was specified) to the
dest partition on the current device.
help [command]
prints general help, or help on command if specified.
mkfs partition fs-type
make a filesystem fs-type on partition. fs-type can be one of "FAT", "ext2" or "linux-swap".
mklabel label-type
Creates a new disklabel (partition table) of label-type. label-type should be one of "bsd", "gpt", "loop", "mac", "mips",
"msdos", "pc98" or "sun".
mkpart part-type [fs-type] start end
make a part-type partition with filesystem fs-type (if specified), beginning at start and ending at end (in megabytes).
part-type should be one of "primary", "logical" or "extended"
mkpartfs part-type fs-type start end
make a part-type partition with filesystem fs-type beginning at start and ending at end (in megabytes)
move partition start end
move partition to start at start and end at end. Note: move never changes the minor number
name partition name
set the name of partition to name. This option works only on Mac and PC98 disklabels. The name can be placed in quotes, if
necessary
print displays the partition table
quit exits parted
resize partition start end
resize the filesystem on partition to start at start and end at end megabytes
rm partition
deletes partition
select device
choose device as the current device to edit. device should usually be a Linux hard disk device, but it can be a partition,
software raid device or a LVM logical volume if that is necessary
set partition flag state
change the state of the flag on partition to state. Flags supported are: "boot", "root", "swap", "hidden", "raid", "lvm" and
"lba". state should be either "on" or "off"
