4.10 Install premium feature license key
A premium feature allows the use of additional functions of the IBM TotalStorage
DS300 and DS400. These additional premium features are, for example, support
for 5 to 256 Flashcopys, and the EXP400 expansion unit attachment. When one
of these premium features is purchased, a booklet with a
purchase validation
code
is delivered. This booklet also contains documentation on the procedure to
follow to retrieve the feature
license key
. See 3.6, “Premium feature license keys”
on page 54.
When a premium feature license key is retrieved, it must be installed into the
DS300/DS400 controller. This section describes the installation of a premium
feature license key using the EXP400 expansion unit premium feature as an
example.
1. Using the command line interface, the command show license displays the
license information for the IBM DS300 or DS400. It also provides information
about available additional features. In the example shown in Figure 4-147, the
external channels are not enabled (the EXP400 expansion unit uses external
channels) and the default number of 4 snapshots (Flashcopys) are allowed.
