7.3.7 Configure (CONFIG) Utility
The Configure Utility locates and adds new devices to an HS array controller’s
configuration.
7.3.7.1 When to Use the Configure Utility
You can run the Configure Utility whenever new devices are added to the HS
array controller.
7.3.7.2 Description
The Configure Utility searches all PTL device combinations to determine what
devices exist on the subsystem. It adds those new devices that are found. The
Configure Utility does not initialize these devices, and it does not add units or
storagesets.
Note
Currently, the Configure utility does not add tape loaders. You must
configure tape loaders manually with CLI commands.

You can run the Configure Utility on either a virtual terminal or a maintenance
terminal.
Before executing the RUN CONFIG command, add your new devices to your
subsystem’s storage shelves, following the steps in the device warm swap
procedures described in Chapter 5.
