► The pvcreate command initializes partitions for use by LVM. Initialize the two new DASD
partitions.
# pvcreate /dev/dasde1 /dev/dasdf1
Physical volume "/dev/dasde1" successfully created
Physical volume "/dev/dasdf1" successfully created
► Verify that the physical volumes were created with the pvdisplay command:
# pvdisplay /dev/dasde1 /dev/dasdf1
"/dev/dasde1" is a new physical volume of "1.15 GiB"

Creating a single volume group
The vgcreate command can be used to create a volume group named homevg from the two
partitions. Use the vgdisplay homevg command to verify the volume group was created:
# vgcreate homevg /dev/dasde1 /dev/dasdf1
Volume group "homevg" successfully created
# vgdisplay homevg
