Considerations when changing Storage Management Subsystem configurations z/OS DFSMSdfp Storage Administration SC23-6860-01 |
|
When activating a new SMS
configuration, you have two options for
keeping the currently active SMS configuration information:
Restriction: Any
SMS status that is changed using the SETSMS command is overridden
by the MVS status if a new configuration is activated. See z/OS MVS System Commands for
information on the SETSMS operator
command.
Requirement: All systems
in the SMS complex must be running in the same mode.
When an SMS control data set that supports only eight names is accessed for update on a system running in 32-name mode, you must convert the data set to a new, incompatible format in order to support 32 names. Confirm this conversion using the operator console or the ISMF. This conversion is permanent, so you should make copies of your control data sets before the system mode is converted. |
