Xsan will not mount any volume that has the same name as any existing volume or folder located at /Volumes/.
Unlike some mounting mechanisms that automatically resolve name conflicts (for example, the Finder appends characters to each mounted volume name), the Xsan backend agent simply won’t mount the volumes.
To avoid this issue, create a unique name for each volume to be mounted.
An Xsan volume can’t be renamed in the Finder.
You can’t change the name of a mounted Xsan volume via the Finder. If you try, you get a message saying the name you’ve typed cannot be used, even if it is an acceptable Xsan volume name.
To rename an Xsan volume, you must use Xsan Admin to reinitialize the volume.
