HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

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 VSP.
CAUTION: Use the -F option with caution, because some errors can prevent a virtual machine
from working properly on the target VSP.
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 VSP after it is migrated successfully to the target VSP. Run the hpvmstatus command
to see that the state of the virtual machine is now Off(NR) on the source VSP and the guest is
On(OS) on the target VSP. The guest is running on the target VSP and is, therefore, considered
Runnable.
This mechanism allows the same virtual machine to be configured on multiple VSPs, while still
preventing accidental booting of the same guest on multiple hosts simultaneously. Each virtual
machine must be Runnable on only one VSP 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 VSP, 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 VSP 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 or vPar that is being managed by Matrix OE, use Capacity
Advisor to collect utilization data before you migrate the virtual machine. Otherwise, the utilization
information for the VSP prior to the migration is lost.
Table 33 lists the options to the hpvmmigrate command.
NOTE: Online migration is supported only with VMs. You can use only offline migration with
vPars.
Table 33 Options to the hpvmmigrate Command
DescriptionOption
Attempts to abort an online vm 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.
