Standby CoD disk sets
You can use the IBM Standby Capacity On Demand (Standby CoD) offering by
ordering Standby CoD disk sets.
A Standby CoD disk set contains 16 disk drives of the same capacity and 10 000,
or 15 000 RPM.
When you initially order Standby CoD disk drive features, you must sign a
Standby CoD agreement. Each subsequent order for Standby CoD features requires
a supplement to the agreement.
To activate Standby CoD disk drives (and exchange them for regular disk drives),
you must order a feature exchange. This results in the removal of the Standby CoD
feature and the addition of the corresponding regular disk drive feature of the
same capacity and speed. The transaction is invoiced at the differential price
between the features removed and added.

Use the Standby Capacity On Demand (Standby CoD) feature codes to order

Each disk set feature provides 16 Standby CoD drives. Table 19 provides the
various Standby CoD disk drive sets that you can order (based on disk size and
RPM), and the feature codes to use.
