+ This command will move all secondary instances away from the
+ given node. It works only for instances having a drbd disk
+ template.
+ </para>
+
+ <para>
+ The new location for the instances can be specified in two ways:
+ <itemizedlist>
+ <listitem>
+ <simpara>as a single node for all instances, via the
+ <option>--new-secondary</option> option</simpara>
+ </listitem>
+ <listitem>
+ <simpara>or via the <option>--iallocator</option> option,
+ giving a script name as parameter, so each instance will
+ be in turn placed on the (per the script) optimal
+ node</simpara>
+ </listitem>
+ </itemizedlist>

+
+ <para>
+ This command will fail over all instances having the given
+ node as primary to their secondary nodes. This works only for
+ instances having a drbd disk template.
+ </para>
+
+ <para>
+ Normally the failover will check the consistency of the disks
+ before failing over the instance. If you are trying to migrate
+ instances off a dead node, this will fail. Use the
+ <option>--ignore-consistency</option> option for this purpose.
