HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

a problem, it is reported, and the virtual machine is not migrated. You can specify the -F option
(force) to suppress the errors and force the virtual machine migration to the target VM Host.
CAUTION: Use the -F option with caution, because some errors can prevent a virtual machine
from working properly on the target VM Host.
The -F option is deprecated in Integrity VM commands; this option should be used only at the
direction of HP Support
By default, Integrity VM retains the virtual machine configuration and marks it Not Runnable
(NR) on the source VM Host after it is migrated successfully to the target VM Host. Run the
hpvmstatus command to see that the state of the virtual machine is now Off(NR) on the source
VM host and the guest is On(OS) on the target VM Host. The guest is running on the target VM
Host and is, therefore, considered Runnable.
This mechanism allows the same virtual machine to be configured on multiple VM Hosts, while
still preventing accidental booting of the same guest on multiple hosts simultaneously. Each
virtual machine must be Runnable on only one VM Host at any given time to prevent the
possibility of two virtual machines using the same SAN storage at the same time. Use the
hpvmmodify command, if necessary, to mark the virtual machine Runnable on only the VM
Host, and Not Runnable on all other hosts that know about that virtual machine configuration
information.
NOTE: Mark a migrated virtual machine as Runnable only in rare circumstances and with
great care. Inappropriate use can cause disk corruption.
When you invoke the hpvmmigrate command, you must specify the name of the guest to be
migrated and the target VM Host system.
Specify the guest using one of the following options:
• -P source-vm-name to specify the guest name
• -p source-vm_number to specify the virtual machine number
Specify the target host by including the –h option and specifying one of the following:
• Target host alias for the private, high-speed network connection
• Target host IP address of the private, high-speed network connection
NOTE: If you migrate a virtual machine that is being managed by ID-VSE, use Capacity Advisor
to collect utilization data before you migrate the virtual machine. Otherwise, the utilization
information for the VM Host prior to the migration is lost.
Table 9-3 lists the options to the hpvmmigrate command.
Table 9-3 Options to the hpvmmigrate Command
DescriptionOption
Attempts to abort an online guest migration.
-A
For offline migrations, causes hpvmmigrate command to boot the
virtual machine on the target automatically after the migration process
is complete. If the -b option is specified for an offline migration, all
backing stores must be copied.
-b
For offline migrations, specifies the number of virtual CPUs for which
this virtual machine will be configured on the target.
-c number-vcpus
