The vgcreate command can be used to create an LVM volume group. In this example, physical volumes /dev/sdb1 and /dev/sdc1 are added to a volume group named myVG. This assumes that both /dev/sdb1 and /dev/sdc1 have been set up as LVM physical volumes.
~]# vgcreate myVG /dev/sdb1 /dev/sdc1
The vgdisplay command can be used to verify the LVM volume group was created.
~]# vgdisplay ---Volume group--- VG Name myVG . . .
Next, create a logical volume.
