You can find the installation and other commands located in various directories. Add these directories to your PATH environment variable on each system.
#
PATH=/usr/sbin:/sbin:/usr/bin:\
/usr/lib/vxvm/bin:/opt/VRTSvxfs/cfs/bin:\
/opt/VRTSvcs/bin:/opt/VRTS/bin:\
#
setenv PATH /usr/sbin:/sbin:/usr/bin:\
/usr/lib/vxvm/bin:/opt/VRTSvxfs/cfs/bin:\
Do not define paths for the root user to a cluster file system in the LD_LIBRARY_PATH variable. You can define $ORACLE_HOME/lib in LD_LIBRARY_PATH for the oracle user.
The path defined as /opt/VRTSob/bin is optional unless you choose to install Veritas Enterprise Administrator.
