.
Create the logical volume.
In the following example, the command creates the logical volume
(lvol1: 100 MB) by using the vg01 volume group:
# lvcreate -L 100M -n lvol1 vg01
Logical volume "lvol1" created

.
Create a file system.
The following example shows how to use the mke2fs command to create
a file system on the lvol1 logical volume:
# mke2fs /dev/vg01/lvol1
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
25688 inodes, 102400 blocks
5120 blocks (5.00%) reserved for the super user
First data block=1
13 block groups
8192 blocks per group, 8192 fragments per group
1976 inodes per group
Superblock backups stored on blocks:
8193, 24577, 40961, 57345, 73729

The following example shows how to mount the logical volume to the /
mnt/lvol1 directory:
# mount /dev/vg01/lvol1 /mnt/lvol1
When Moving a Logical Volume Created on a SCSI Device in a Single-
Path Environment to an HDLM Device
This subsection explains the procedure for moving a logical volume created
on a SCSI device in a single-path environment to an HDLM device in a multi-
path environment. Use the following procedure to configure the environment
in Figure 3-30 Device Configuration When a Logical Volume on a SCSI Device
Is Moved to an HDLM Device on page 3-172 .
