This command ensures that all sites have a consistent copy of data before switching the workload site from one site to another. Therefore, the symstar halt command should be used before the workload switch in case of a disaster at the workload site of an SRDF/Star configuration1

The two factors that define Capacity Management are I/O capacity and storage capacity. I/O capacity refers to the ability of the system to handle the incoming and outgoing data traffic from the hosts or applications. Storage capacity refers to the amount of disk space available to store the data. Capacity Management is the process of planning, monitoring, and optimizing the use of these resources to ensure optimal performance, availability, and efficiency of the system.
