Figure 31 Expand Datastore window
3.Enter the requested new capacity in the Requested Datastore Capacity box. The following rules apply when expanding datastores:
•A datastore can be expanded only if it is located on a single disk on an array that supports provisioning by the Storage Module for vCenter.
•The requested capacity cannot exceed the total capacity of the storage pool.
•The requested capacity cannot be less than or equal to the original datastore capacity.
When you enter the new capacity, the Expand Datastore window displays the Capacity Before and Capacity After values for the related storage pool.
Capacity Before and Capacity After are approximate values. The actual virtual disk size might be slightly larger to accommodate the VMware overhead.
4.Click Finish to expand the selected datastore.
A dialog box notifies you that you can view the progress of the task in the Recent Tasks pane at the bottom of the vSphere Client window.
5.Click OK.
TIP: No manual data refresh is necessary. When a provisioning operation is complete, the Storage Module for vCenter data is refreshed automatically.

You can delete a datastore if it is not used by a VM or VM template.
•If the disk used by the datastore is replicated using snapshot, the delete operation will fail.
•If the datastore is used by a VM or VM template, the delete operation will fail.
