The ``-I (--iallocator)`` option specifies the instance allocator

|
plugin to use. If you pass in this option the allocator will select

|
nodes for this instance automatically, so you don't need to pass them
|
| 623 |
|
with the ``-n`` option. For more information please refer to the

instance allocator documentation.

The ``-t (--disk-template)`` options specifies the disk layout type

The third form (when passing either the ``--iallocator`` or the

``--new-secondary`` option) is designed to change secondary node of

the instance. Specifying ``--iallocator`` makes the new secondary be

selected automatically by the specified allocator plugin, otherwise

the new secondary node will be the one chosen manually via the

``--new-secondary`` option.
