How to use StopX37/II

MainView SRM storage-management services are divided into functions.

In addition to controlling message and tracing activity, the SMFUNCxx member points to members SMFLSTxx and SMRLSTxx which select resources and control the operation of MainView SRM functions. For information about activating and controlling functions, see Using-MainView-SRM-products.

Each StopX37/II function must be specified in the SMFUNCxx member to be available and must be active to provide services. For details about defining and activating functions, refer to Using-MainView-SRM-products.

The following tables list the functions by application, alphabetically, and by the global parameters StopX37/II accesses.
