HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

The following examples show how to add various device types to the storage pool:

• File:

# hpvmdevmgmt -a gdev:/var/opt/hpmv/ISO-images/hpux/112350GOLD.ISO:attr:PRESERVE=YES

• VxVM volume:

# hpvmdevmgmt -a gdev:/dev/vx/rdsk/guestdg/vxvm_g2:attr:PRESERVE=YES

To remove a device from the storage pool, used the following command:

# hpvmdevmgmt -d gdev:/dev/rdisk/disk23

NOTE: Adding devices to the storage pool does not prevent them from being used by the

HP-UX operating system or other Integrity VM commands.

The storage pool does not fully support lunpaths or directories. In addition, Virtual Machine

Management (VMM), a layer between Integrity VM and LSM, has no way to insert or eject a

DVD, because this is done from the virtual console.

8.2.2 Registering and Unregistering a VM

A VM is registered when it is runnable, modifiable, and visible. When a VM is not registered, it

is not visible to the graphical tools, such as LSM, and you cannot modify it or start it. When you

are set:

• runnable_status=enabled

• modify_status=enabled

• visible_status=enabled

VMM and LSM ensure that a virtual machine is registered (and, therefore, runnable) on only

one VM Host at a time.

When a virtual machine is unregistered, the following attributes are set:

• runnable_status=disabled

• modify_status=disabled

• visible_status=disabled

After a migration, the hpvmmigrate command sets the virtual machine on the source host as

unregistered. The VM is marked not runnable, not visible, and not modifiable. The hpvmstatus

command lists these attributes:

# hpvmstatus -P vmname -V

When the graphical tool queries the register_status, the value of visible_status is

returned. If the VM is not visible, you cannot visualize it with the graphical tools, and therefore;

you cannot modify it or run it. You can set the register_status of a VM to enabled or disabled

with the hpvmmodify command.

You can set the register_status of a VM to enabled or disabled with the hpvmmodify -x

register_status command.
