public String getMode() {

<p>
The metadata configuration mode for provisioning Metadata IOPS for an FSx for Lustre file system using a
<code>PERSISTENT_2</code> deployment type.
</p>
<ul>
<li>
<p>
To increase the Metadata IOPS or to switch from AUTOMATIC mode, specify <code>USER_PROVISIONED</code> as the
value for this parameter. Then use the Iops parameter to provide a Metadata IOPS value that is greater than or
equal to the current number of Metadata IOPS provisioned for the file system.
</p>
</li>
<li>
<p>
To switch from USER_PROVISIONED mode, specify <code>AUTOMATIC</code> as the value for this parameter, but do not
input a value for Iops.
</p>
<note>
<p>
If you request to switch from USER_PROVISIONED to AUTOMATIC mode and the current Metadata IOPS value is greater
than the automated default, FSx for Lustre rejects the request because downscaling Metadata IOPS is not
supported.
