Indicates the process identifier to switch over to another host. Options are ‘hostN’ and ‘rankN’ where ‘N’ corresponds to the number associated with a host or rank in the Network section of the gpudb.conf file; e.g., ‘host[N].address’ or ‘rank[N].host’. If ‘hostN’ is provided, all processes on that host will be moved to another host. Each entry in this array will be switched over to the corresponding host entry at the same index in input parameter destinations. The user can provide a single element (which will be automatically promoted to a list internally) or a list.
