HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration
• If the volume group is to remain deactivated, the VM Host administrator can manually add
the physical volume as a restricted device with the hpvmdevmgmt command.
• Or, after activating the volume group, execute the hpvmhostrdev command, so that the
VM Host storage management database is updated accordingly.
An HP-UX system administrator can deactivate a volume group using the vgchange command.
It can also be deactivated, if it is a shared LVM (SLVM) volume group, whenever the associated
Serviceguard cluster is reconfigured, or the VM Host system is rebooted. Take care to check that
all SLVM volume groups are activated after a VM Host reboot or Serviceguard cluster
reconfiguration.
8.1.3 Managing Existing Integrity VM Guests With LSM
You can import existing Integrity VM guests that are configured with whole LUNs, and perform
the following LSM operations on these VMs: Online Move, Power On, Power Off, and Unmanage.
All other operations are not supported with these imported guests.
Integrity VM Hosts that are managing only VMs with whole LUNs do not need to be configured
with Serviceguard and SLVM. If you plan to create new guests on that VM Host, follow the steps
in Section 8.1 (page 143).
8.1.4 Managing Guests using gWLM
Guests configured with processing power specified in cycles instead of percentage are
incompatible with gWLM A.02.50 and earlier versions.
If gWLM/Insight Dynamics — VSE produces an error message similar to the following, a guest
is configured with the processing power specified in cycles:
A VM encountered with no size
This is apparent when using gWLM A.02.50 with Integrity VM A.03.00. You can correct the
problem by modifying the guest and specifying processing power in percentage rather than CPU
cycles. For example, to modify the guest named compass1 to use 10% of the CPU processing
power, enter the following command
# hpvmmodify -P compass1 -e 10
You must boot the guest to initiate this setting for gWLM.
Alternatively, upgrade gWLM to A.03.00 for use with Integrity VM A.03.00.
8.2 Integrity VM Virtualization Provider
Integrity VM now supports an additional provider, the Integrity VM Virtualization Provider.
The Integrity VM Virtualization Provider, used with the logical server feature in Insight Dynamics,
enables virtual to virtual migration with logical server management (LSM). A logical server is a
set of configuration information that you create, activate, and move across physical and virtual
machines. It contains the logical server definition and description, including the server computer
resources (for example, the number of CPU cores and amount of memory), and the server
connections to storage fabric and networks.
For information about LSM and VMM, see documentation on the Business Support Center
website.
8.2.1 Adding and Removing Devices
Integrity VM adds devices not in use by the VM Host automatically. You can add devices that
are not automatically added by using the hpvmdevmgmt gdev PRESERVE attribute. The
following device types require manual addition:
• File backed disks
• File backed DVDs
• VxVM volumes
