If your scheduler is not running under CAD, any changes made to dsm.sys and dsm.opt will not be known to that scheduler process until it is restarted.
You should also review the output of 'dsmc q opt' and 'dsmc q inclexcl' for
containing what you actually want, as "compiled" specifications. An option of
"virtualmountpoint /" seems pointless.
