If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

A persistent volume (PV) is the "physical" volume (such as a hard disk drive or solid state drive) on the host machine (node) that stores your persistent data, whereas a persistent volume claim (PVC) is a reference to a persistent volume, used by a pod. A Shared Volume contains both a Persistent Volume and a Persistent Volume Claim and is typically used for an Amazon Web Services (AWS) Elastic File System (EFS).

The oc get sharedvolumes (or oc get sv) command will return the list of Shared Volumes. Access Modes can be one or more of the following

~]$ oc get sharedvolumes
AME                 FILE SYSTEM   ACCESS POINT            PHASE   CLAIM                      MESSAGE
my-shared-volume    fs-0123cdef   fsap-0123456789abcdef   Ready   my-persistent-volume-claim 

The oc describe sharedvolume command can be used to show more details about a Shared Volume.
