HP-UX vPars and Integrity VM V6.3 Administrator Guide

Table 27 Options to the hpvmmigrate command (continued)
DescriptionOption
For offline migrations, specifies the number of virtual CPUs for which this
VM will be configured on the target.
-cnumber-vcpus
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 is to be copied.
-C
For offline migrations, causes the hpvmmigrate command to
automatically shut down a running guest before migrating the VM
configuration to the target VSP. Consider migrating the guest online by
using the -o option instead.
-d
Deletes the VM from the source VSP after migrating the VM to the target
VSP system. If not specified, the VM is marked Not Runnable on the
source VSP after migration.
-D
For offline migrations, specifies the percentage of CPU resources to which
the VM's virtual CPUs is entitled. During peak system CPU load, the
entitlement is the guaranteed minimum allocation of CPU resources for
this VM. The percent can be set to an integral value between 0 and 100.
If the value specified is less than 5, the VM 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 CPU entitlement of the VM 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 VM, whether or not there are resource validation
errors (such as resource conflict, resource nonexistence, and so on). 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 VM 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 must
be used only if instructed by HP Support.
-F
Specifies the host alias or IP address of the target VSP machine to which
the VM is 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 must 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
is 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.
