Privilege Class: G
Use DEFINE VECTOR to attach a Vector Facility (VF) to one or more processors in
your virtual machine configuration.
Notes:
1. At least one Vector Facility must be installed in the real machine.
2. The directory must allow your virtual machine to use the Vector Facility.
3. Multiple addresses may be specified in the form of a list of single numbers or
ranges. The addresses may be any hexadecimal value from 0 to 3F, providing a
CPU with that same address has been defined.
ALL
specifies that a virtual VF is to be defined for every virtual CPU in the
configuration that does not already have one.
nn identifies a single virtual CPU address.
nn1-nn2
identifies a nonwrapping pair of addresses separated by a hyphen and not
separated by any blanks.
1. If you define a new virtual Vector Facility for a virtual CPU currently dedicated to
a real processor without an installed Vector Facility, you must rededicate
(UNDEDICATE and then DEDICATE) the virtual CPU.
2. When you redefine a virtual CPU using DEFINE CPU nn AS mm, you also
redefine the associated Vector Facility.
3. For additional information, see “Usage Notes” on page 113.
To define a virtual Vector Facility for CPU 1, enter:
define vector 1
To define virtual Vector Facilities for CPUs 0, 2, and 3, enter:
define vector 0 2-3
