Do the following to resolve this issue:
1. Login as vi-admin to the console and 'sudo su root' (enter vi-admin password)
2. Save the original /etc/bash.bashrc file to a backup in case something goes wrong.
3. Add these lines to the end of the bash.bashrc file:
alias vifptarget="source /opt/vmware/vma/bin/vifptarget"
4. Save the file and exit root access.
5. As vi-admin, execute source /etc/bash.bashrc.
This should do it.
