You can 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.
- In the vSphere Web Client navigator, select .
- Right-click the datastore to rename, and select Rename.
- Type a new datastore name.
The vSphere Web Client enforces a 42 character limit for the datastore name.
