Extend a Datastore that Uses a LUN

With the Oracle vSphere Plug-In for Oracle Flash Storage Systems, you can extend the size of a datastore that utilizes an Oracle FS System LUN without adding extents.

This option differs from the built-in datastore extend feature of vSphere, which allows you to extend a datastore by adding another LUN to the datastore. When you extend a datastore with the Oracle vSphere Plug-In for Oracle Flash Storage Systems option, you extend the underlying LUNs on the Oracle FS System. This option is available only for datastores created on Oracle FS System LUNs.

Note: Oracle recommends that you NOT extend datastores by creating new Oracle FS System LUNs and adding them as extents. Instead, you should extend the capacity of the existing LUN.

In the vSphere inventory tree, select a datastore to be extended.
Important! This datastore must contain LUNs from a single Oracle FS System.
Right-click the datastore and select Manage Oracle FS Storage > Extend Datastore.
Provide authentication credentials for the Oracle FS System if you have not already provided them.
In the Extend Datastore window, enter a new capacity for the datastore by doing one of the following:
- To extend the total capacity of the datastore, enter a new capacity in the Total New Capacity (GB) field.
- To extend the capacity of one or more associated LUNs, select Manually adjust the capacity of underlying LUNs, and then enter a new capacity value for each LUN in the New Capacity (GB) field.
Click OK.
Result:The size of the datastore is extended.
