<p>How I will be able to change the access mode in the persistent volume claim access mode? currently it is showing as RWO, and I need to change it as RWX?</p>

<p>Many thanks in advance.</p>

<p><code>accessModes</code> in PersistenceVolumeClaim (PVC) is an <strong>immutable field</strong> and <strong>cannot be changed once applied</strong>. Even though you can change the bounded PersistentVolume (PV) <code>accessModes</code> using the same way as suggested by @aurelius which will automatically updated PVC <code>accessModes</code></p>
