C.3.8 Declaring the CDA 7 Subsystem under GCOS 7

The version of FGF supporting CDA 7 subsystem does not have any new

commands for management of these subassemblies.

C.3.8.1 Global Method

Firstly, you should be aware that if MSC4 subsystems are present in the

configuration, MNCONF will assign slots occupied by the PxM cards to WSP

cards, and that substitution will be compulsory.

LSS subsystems (and channels and disk external identifiers) will not be assigned.

Other PRM or NCC7 type cards may be moved.

The procedure is as follows:

1. Starting from the running configuration (CONFIG_OLD), execute a

MODIFY command under MNCONF and add CDA subsystems to create a

new configuration (CONFIG_NEW), based on the original configuration.

The result of this operation gives:

− The future slots for WSP cards.

− The list of IOM cards to be removed so that WSP cards can be installed.

2. In the new configuration, CONFIG_NEW, use the "IOM" command to look

for possible slots for cards which were removed in the previous step.

3. In CONFIG_OLD, execute one or more MOVE commands to the slots found

in step 2, for the IOMs deleted in step 1, in order to make room to install the

WSP cards. At the end of this step, a configuration will be created which may

be called CONFIG_TEMPRY and which will contain the necessary free slots.

4. In CONFIG_TEMPRY, execute a MODIFY command to insert WSP cards

supporting CDA subsystems.

This creates the final configuration, for example named CONFIG_MYCDA.
