Example 2 with SiteParam

use of com.emc.storageos.model.dr.SiteParam in project coprhd-controller by CoprHD.

the class DisasterRecoveryService method initStandby.

/**
 * Initialize a to-be added/resumed target standby
 * a) re-set all the latest site related info (persisted in ZK) in the target standby
 * b) vdc properties would be changed accordingly
 * c) the target standby reboot
 * d) re-set zk/db data during the target standby reboot
 * e) the target standby would connect with active and sync all the latest ZK&DB data.
 *
 * Scenarios:
 * a) For adding standby site scenario (External API), the current site will be demoted from active to standby during the process
 * b) For resuming standby site scenario (Internal API), the current site's original data will be cleaned by setting new data revision.
 * It is now only used for resuming long paused (> 5 days) standby site

 * @param configParam
 * @return
