A single controller support since GDPS/CA 2.2

CCB planned the asymmetric long distance GDPS/CA ZDL architecture to control the site switch 1000 KM away. They will follow the manual to define two controllers, but the backup controller will be up on-demand. Per GDPS/CA product requirement, it's a unsupported configuration for only one running controller, so we issue the RFE here for product supporting.

    What kind of switch are you referring to (e.g., workload, controller, etc.)? Pls provide a step by step procedure on what CCB envisions doing the whatever switch type and why they want this.

    It's a site switch which means multiple workloads switch here.
    CCB plans to utilize the force site switch procedure based on GDPS/CA script.

    SWITCH WORKLOAD=ALL SITE=PLEXNP1 FORCE

    As we pointed out, the primary goal of CCB A-A is to provide the best RTO & RPO during disaster recovery scenario, by leveraging our GDPS/CA Active/Standby architecture. CCB also puts Go-Home procedure at lower priority, and only in planned manner.

    CCB will define two controllers as the GDPS/CA IG manual requires. But they will only keep a primary controller running in target site, but the other controller will be up on-demand.

    GDPS/CA architect told us we need to open a RFE for this official support.

    Thanks!
