v Go to the DSFA website and change the assigned value from the current number
of terabytes (TB) to 0 TB. This value, in effect, makes the feature inactive. If this
change is made, you can later go back to DSFA and reactivate the feature, up to
the previously purchased level, without having to repurchase the feature.
Regardless of which method is used, the deactivation of a licensed function is a
non-disruptive activity but takes effect at the next machine IML.
Note: Although you do not need to specify how the licenses are to be applied
when you order them, you must allocate the licenses to the storage image
when you obtain your license keys on the IBM Disk Storage Feature
Activation (DSFA) website.
Operating environment license (239x Model LFA, OEL license, 242x
machine type)
The operating environment model and features establish the extent of IBM
authorization for the use of the IBM System Storage DS operating environment.
For every storage unit, you must order an operating environment license (OEL).
This operating environment license support function is called the 239x Model LFA,
OEL license on the 242x hardware machine type. The OEL licenses the operating
environment and is based on the total physical capacity of the storage unit (base
model plus any expansion models). It authorizes you to use the model
configuration at a given capacity level. Once the OEL has been activated for the
storage unit, you can configure the storage unit. Activating the OEL means that
you have obtained the feature activation key from the DSFA website and entered it
into the DS Storage Manager.
Feature codes for the operating environment license
You must order an operating environment license (OEL) feature for every storage
unit.
