When you need to add virtual machines to a datastore, or when the virtual machines running on a datastore require more space, you can dynamically increase the capacity of a VMFS datastore.
About this task
If a shared datastore has powered on virtual machines and becomes 100% full, you can increase the datastore's capacity only from the host that the powered on virtual machines are registered on.
- Click Storage in the VMware Host Client inventory and click Datastores.
- Click New datastore.
- Click Increase the size of an existing VMFS datastore and click Next.
