Oracle Linux 7 mounting SAN storage issue

I have a scenario where I am trying to mount SAN storage to my linux machine. My environment details are- 1. Oracle VM manager for VM creation 2. Fiber Channel HP3PAR SAN storage attached as physical disk to my VM 3. Oracle Linux version -OEL 7.4 Below steps I have been doing as earlier worked smoothly but not now- 1. Login as root user on VM Running 2. fdisk utility to check attached disks fdisk -l It shows 2 disks /dev/xvdb & /dev/xvdc where /dev/xvdc appeared after attaching the SAN storage to VM. 3. Applying mount command to mount /dec/xvdc on location /u01/oracle/config where /u01/oracle/config is empty mount /dev/xvdc /u01/oracle/config 4. After this the command screen cursor just blinks and nothing happens. Further I have checked whether the mount was successful, no it is not. Running the command 'df -h' and 'mount' doesn't shows the storage was mounted to requested location.
