Hi Tirthaghy,
It is not clear what you are trying to accomplish but,
this command will show the volume with the exact name svm03 and the volume(s) which start with the name test
::> vol show svm03|test*
this command is the other way around, it will show the volume with the exact name test and the volumes which start with the name svm03
::> vol show test|svm03*
Regards
Emile
