How to correct mount CIFS volume from linux ??

Hi All

       I am learning NetAPP...and create a CIFS volume..volume name is engineering.

now I could let Win10 mount it and write a file well. (mount path : \\SVM_IP\nsroot\engineering)

then I  want to using linux to mount CIFS volume...

I create a (cifs) file to provide credential information like below

-----------------

username=plateuser
password=vu/41234
domain=abc.com.tw

------------

then add setting in /etc/fstab

----------------

<SVM_IP>:/engineering /mnt/test cifs ro,nouser,noexec,nosuid,credentials=/usr/XXX/yyy/ZZZ/cifs 0 0

----------------------

but I tested mount..it show BAD UNC...

which parameter or setting that I forgot or set error ?

thanks
