To configure the cryptographic features online and offline, you must use the support element (SE) panel.
Before configuring a feature offline, it is strongly recommended that you deactivate the feature first from the ICSF Coprocessor Management panel. You need to 'deactivate' the feature in ALL partitions that are using that feature. This allow jobs to complete before the feature is varied offline. You use the Configure On/Off service on the Support Element panel to take the feature offline (standby).
After you configure the feature offline from the SE panel, press ENTER on the Coprocessor Management panel to verify that the feature is offline. This configuring is done to remove and replace features or to load new code for the cryptographic features.
To bring a feature back online, use the SE panel again. If a feature was deactivated and then configured offline, you will need to activate it again through the Coprocessor Management panel.
There are no z/OS operator commands to configure the devices online or offline.
