HP-UX System Administrator's Guide: Routine Management Tasks

3. Find a volume group that has as much free space as you need.
Select Tools, Disks and File Systems, File Systems. Click on the Volume Groups
tab. This will display a list of volume groups and the free space for each.
You might see, for example, that volume group vg01 has 600MB of free
(unallocated) space.
4. Identify a volume group with sufficient free space for your new Logical Volume.
5. Click on the Logical Volumes tab. Select Create LV... from the list of actions on
the right side of the page.
6. Select the volume group you’ve identified to provide the space for the Logical
Volume. Enter a name, size and other configuration information for the new Logical
Volume. Click on Create.
7. For example, you might create a logical volume namedlvol7, occupying 500MB.
To share the new file system(s) with other systems in the workgroup, go to
Tools Network Services Configuration Network File Systems page in the HP System
Management Homepage, select the Share/Unshare File Systems (Export FS) item
and use the following page to define which local file systems are shared to which
external systems. See HP-UX System Administrator’s Guide: Logical Volume Management.
As a result of all this, HP SMH creates a new logical volume and mounts it on a new
file system, for example, /dev/vg01/lvol7 mounted on /work/project5.
Creating a File System
You can create a new file system from a Logical Volume using HP SMH.
1. Access the HP SMH Homepage.
2. Select Tools, Disks and File Systems, Logical Volumes. Click on the desired
Add File System actions on the right side of the page, Add HFS... for example.
3. Enter a Mount Point and click Select Unused LV... A list of available Logical
Volumes will be displayed.
4. Select the desired Logical Volume. Click Select. You will be returned to the Add
File System page.
5. Select the desired File System attributes and Mount Options. Click Add file system.
Adding a Logical Volume with Mirroring
For detailed discussion of mirroring see HP-UX System Administrator’s Guide: Logical
Volume Management. The following example uses HP SMH.
1. Decide how many mirror copies you want.
For the purposes of this example, we’ll assume you want one mirror; that is, you’ll
be keeping two copies of the data online, the original and a mirror copy.
