Recovering from a systems failure in the SMS complex

To provide for recovery procedures, you should leave one system or system group name slots empty in the corresponding function panels. In case a problem occurs requiring that a system that is defined within the configuration as part of a system group be specified by its specific name (such as, hardware failure), you can add it without disrupting the rest of the system group of SMS complex.

You can initiate recovery with the following steps:

Use the ISMF CDS Application to add the system name to the SMS configuration.
Activate the configuration, either from ISMF or from the operator console.
Use the VARY SMS operator command to make any necessary changes to the configuration.
Remove the system name from the configuration and reactivate the configuration once the problem has been corrected.
