<div><p>If you elect to partition at the IOP-level, you can switch certain
|
||
|
|
IOPs and all its attached devices between partitions that share the same bus
|
||
|
|
dynamically. </p>
|
||
|
|
<p>The partition that currently owns the IOP must not be in use before you
|
||
|
|
switch the IOP to another partition.</p>
|
||
|
|
<p>Switching requires removing the IOP from its current partition and adding
|
||
|
|
it to a different one. In other words, two partitions cannot use the IOP and
|
||
|
|
its devices at the same time.</p>

units that belong to that specific IOP are first removed from the auxiliary
