hpvmsg_move(1M)
NAME
hpvmsg_move -- Initiate an online migration of a virtual machine that has previously been
associated with a Serviceguard package.
SYNOPSIS
hpvmsg_move [-v] [-h target-node | -n target-node] [-P vm-name]
DESCRIPTION
The hpvmsg_move command initiates an online migration (move) of a virtual machine that has
previously been associated with a Serviceguard package. The command moves the virtual machine
and package named in the vm-name argument from the current running node to the target-node
specified with the -h option or the -n option.
The hpvmsg_move command disables package switching during the online migration of the
virtual machine, but does not halt the package. It keeps the package from being switched to a
new node in the event the current node fails. Following a successful online migration, the package
switching is re-enabled.
The hpvmsg_move command is limited to the same restrictions as specified by the hpvmmigrate
command. To be compatible for online migration, both the source VM Host and the target VM
Host must have the same processor family (as reported by the machinfo command). To maintain
active guest network connectivity, configure a vswitch with the same name and connected to
the same subnet on the target VM Host. Also, only whole disk backing storage consisting of SAN
LUNs and null backing store DVD devices are supported for online guest migration storage.
Options
The hpvmsg_move command recognizes the following command-line options and arguments:
-v
Displays verbose information.
-h target-node
Specifies the node to which the virtual machine and package online
migrate. The -h option and the -n option are mutually exclusive.
-n target-node
Specifies the node to which the virtual machine and package online
migrate. This option provides the same functionality as the -h option.
The -h option and the -n option are mutually exclusive.
-P vm-name
Specifies the virtual machine and package to be online migrated.
RETURN VALUES
The command exits with one of the following values:
0: Successful completion.
1: One or more error conditions
occurred.
2: One or more operational failures
occurred.
3: The package is not a virtual
machine package.
4: The package is not up and
running at the operating system.
5: The target node is not a
Serviceguard node.
