HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

Table 33 Options to the hpvmmigrate Command (continued)
DescriptionOption
For offline migrations, physically copies the storage device specified with
the -m option to the target VSP during the migration process. If specified
before the first -m option, it applies to all -m options that specify an
appropriate type of storage. This might take a long time to complete if a
large amount of storage needs to be copied.
-C
For offline migrations, causes hpvmmigrate to automatically shut down
a running guest before migrating the virtual machine configuration to the
target VSP. Consider migrating the guest online by using the -o option
instead.
-d
Deletes the virtual machine from the source VSP after migrating the virtual
machine to the target VSP system. If not specified, the virtual machine is
marked Not Runnable on the source VSP after migration.
-D
For offline migrations, specifies the percentage of CPU resources to which
each of the virtual machines virtual CPUs is entitled. During peak system
CPU load, the entitlement is the guaranteed minimum allocation of CPU
resources for this virtual machine. The percent can be set to an integral
value between 0 and 100. If the value specified is less than 5, the virtual
machine is allocated the minimum percentage of 5%. The default is 10%.
Integrity VM reserves processing power for essential system functions
such as logging, networking, and file system daemons. The -e and the
-E options are mutually exclusive.
-e [:max-percent ]
For offline migrations, specifies the virtual machine's CPU entitlement in
CPU cycles. The cycles are expressed as an integer followed by one of
these units:
• M (megahertz)
• G (gigahertz)
If no letter is specified, the default unit is megahertz. The -e and the -E
options are mutually exclusive.
-E [:max-cycles]
Forces the migration of a virtual machine, whether or not there are
resource validation errors (such as resource conflict, resource
nonexistence, and so forth). Use the -F option rarely and with caution.
This option ignores all resource validation errors, including
oversubscribing of resources.
NOTE: These errors can prevent the virtual machine from booting on
the target VSP. Any validation errors are logged in the Integrity VM
command log.
The -F option is deprecated in Integrity VM commands; this option should
be used only at the direction of HP Support
-F
Specifies the host alias or IP address of the target VSP machine to which
the virtual machine is being migrated. The target machine must be a valid
VSP and must be accessible by the source VSP. Almost all forms of the
hpvmmigrate command require the -h option. For online migration,
the parameter for the -h option should specify a private, dedicated,
high-speed network link to the target VSP.
If you specify a simple non-qualified host name, the hpvmmigrate
command appends -hpvm-migr to the name and checks if a host alias
has been defined for a private network corresponding to the simple name.
Online guest migration does not check to ensure the link is private, but
using a private network is important for efficient and secure online
migrations and to preserve the bandwidth of the regular site network.
