Issue 

While trying to control a VDB (rewind/refresh/start/stop) an error similar to the following is raised:

ERROR : Details : Trying "mount" using dlpx_mount - stty: standard input: Inappropriate ioctl for device
stty: standard input: Inappropriate ioctl for device;mount: wrong fs type, bad option, bad superblock on 10.198.36.222:/public,;
missing codepage or helper program, or other error; (for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program); In some cases useful info is found in syslog - try; dmesg | tail or so;

This message indicates that either the NFS client software is not installed.

Troubleshooting 

Depending on your flavor of Linux, check to see that the appropriate NFS client software is installed. Run the following command to see if the NFS client utilities are installed:

rpm -q nfs-utils

Resolution 

Install the NFS client utilities using the appropriate commands or utilities. For example:

sudo yum install nfs-utils
