Scenario
If PRIMARY stops updating its status, the following events occur,
based on the SFM policy.
- BACKUP2 isolates PRIMARY and removes it from the sysplex. Because PRIMARY and BACKUP2 are connected through the same coupling facility, this can be done without operator intervention.
- BACKUP2 then deactivates all other LPARs in its addressing range, which includes TEST.
- BACKUP2 brings online all processor storage in its addressing range. The storage previously used by TEST is now available to BACKUP2. Also, the shared central processors used by TEST are available to BACKUP2.
- Because BACKUP2 has sufficient processor storage, group members of the multisystem applications on BACKUP2 can take over the workload of their group members on PRIMARY.
