Use the vSphere Client to change the name of an existing datastore. You can rename the datastore that has virtual machines running on it without any negative impact.
Note: If the host is managed by vCenter Server, you cannot rename the datastore by directly accessing the host from the VMware Host Client. You must rename the datastore from vCenter Server.
- Navigate to the datastore.
- Right-click the datastore to rename, and select Rename.
- Enter a new datastore name.
The system enforces a 42 character limit for the datastore name.
