Management).
If the driver for this disk is not already configured into the kernel, you can use HP
SMH to configure it. In this case, a reboot might be required before you can use
the disk.

Adding a Logical Volume
For a detailed discussion of LVM (Logical Volume Manager) see HP-UX System
Administrator’s Guide: Logical Volume Management. The following is a quick reference
using HP SMH.
NOTE: To configure a logical volume with disk striping, you must have more than
one physical volume in the volume group. The option to stripe logical volumes is
hidden in SMH if this is not true (see “Setting Up Disk Striping” in the HP-UX
SystemAdministrator’s Guide: Logical Volume Management).
1. Decide how much disk space the logical volume will need.
For example, you might want to add 200MB of swap, or you might be adding a
new project that you expect to grow to 500MB.
