IBM System Storage DS6000 Series: Copy Services with IBM System z
8.1 Ordering FlashCopy
FlashCopy is an optional licensed function of the IBM System Storage DS6000 series. This
function is also referred to as the Point-In-Time Copy (PTC) licensed function.
All DS6000 series licensed functions are enabled, authorized, managed, activated, and
enforced based upon the physical capacity contained in a 1750 system.
Enablement
This refers to the purchase of a feature number to technically activate the associated licensed
function. Each licensed function is
enabled
for a 1750 system through acquiring the
corresponding feature numbers.
Particularly for FlashCopy, the 1750 feature that must be ordered is the Point-in-Time Copy
(PTC) licensed function, feature #52xx; see Table 8-1.
Table 8-1 FlashCopy features
Each licensed function feature number purchased for a 1750 machine enables that function
for the entire 1750 system.
Authorization
This refers to the purchase of a feature number to establish the extent of IBM
authorization
—license size in terms of physical capacity— for use of an associated licensed function. This
is also referred to as the
authorization level
.
The extent of IBM authorization for the use of a licensed function on a 1750 system is
established by acquiring an 52xx feature number on the 1750 base enclosure. The same
52xx feature numbers acquired to enable a licensed function also establish the extent of
IBM's authorization.
The 52xx feature number on a 1750 base enclosure establishes the authorization level for the
entire 1750 system. For example, a 1750 system with a Model 522 base enclosure and two
Model EX2 expansion enclosures requires the acquisition of 52xx feature numbers only on
the Model 522. Therefore, for licensed functions authorized on the basis of physical
capacity—as in the case of PTC—the authorization level established with the acquisition of
the 52xx feature number on the Model 522 must also cover the physical capacity of the
attached Model EX2 expansion enclosures.
Note: For a detailed explanation of the features involved and the factors to be considered
