Veritas File System (VxFS) ships with VxFS specific binaries for some common UNIX commands such as "cp", "mv", and "df".
These utilities are designed to work specifically with VxFS file systems. When these errors are encountered in the above manner it indicates that the user's PATH most likely is referencing the "/opt/VRTS/bin" path before other system binary locations.
First confirm that VxFS specific binaries are being invoked by default:
# which cp
/opt/VRTS/bin/cp
The cause in this case is confirmed that the "/opt/VRTS/bin" path is in the current user's PATH environment variable before the OS standard paths.
# echo $PATH
To resolve this issue modify the PATH variable so that /opt/VRTS/bin is referenced after the OS standard paths.
