When a system leaves the sysplex, automatic restart management will wait for all the members that specified SYSCLEANUPMEM=YES on the IXCJOIN macro to issue the IXCSYSCL macro before it will perform restarts for elements that were on the failed system.

When a system leaves the sysplex, members of cross-system coupling facility (XCF) groups will be notified through their group user routine. If SYSCLEANUPMEM=YES was specified by a member of the group, IXCSYSCL must be issued to indicate when cleanup has been completed by an XCF member (specified in the MEMTOKEN parameter), for the system that left the sysplex (specified in the FAILEDSYS parameter), or that no cleanup is necessary.
