You can change the name of an existing VMFS, NFS, or Virtual SAN 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.
Browse to Datastores in the vSphere Web Client navigator. See Display Datastore Information in the vSphere Web Client.
- Right-click the datastore to rename.
- Select Rename from the right-click menu.
- Type a new datastore name.
The vSphere Web Client enforces a 42 character limit for the datastore name.
The new name appears on all hosts that have access to the datastore.
