Steps for activating/deactivating cryptographic coprocessors

From your TSO userid, select option 1, Coprocessor Mgmt. On the Coprocessor Management panel, you can select the features you want to activate or deactivate.

When a coprocessor or accelerator is deactivated through the Coprocessor Management Panel, the card is only deactivated for that one LPAR.

Note: On systems running ICSF FMID HCR77B1 or later, the SETICSF ACTivate and the SETICSF DEACTivate commands can also be used to activate or deactivate coprocessors and accelerators.
