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.
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.
The new name appears on all hosts that have access to the datastore.
