Administration Tools
HP-UX provides two tools to manage your LVM configuration:
HP System Management Homepage (HP SMH): An HP-UX tool that provides an easy-to-use
GUI for performing most LVM tasks. HP SMH minimizes or eliminates the need for detailed
knowledge of administration commands, thus saving time. Use HP SMH to manage your LVM
configuration whenever possible, especially when performing a new task. HP SMH can help
you with the following tasks:
Creating or removing volume groups
◦
Adding or removing disks within volume groups
◦
◦
Activating and deactivating volume groups
◦
Exporting and importing volume groups
◦
Creating, removing, or modifying logical volumes
Increasing the size of logical volumes

◦
Creating and modifying mirrored logical volumes
◦
Creating striped logical volumes
◦
◦
Splitting a mirrored logical volume and merging a mirror copy
◦
Adding and removing mirror copies within mirrored logical volumes
◦
Creating and modifying physical volume groups
To use HP SMH, enter the command /usr/sbin/smh.
For help using HP SMH, see the HP SMH online help.
