Usage Guidelines

  • This operation switches the states of DR Star's two asynchronous remote replication members. After the operation, the asynchronous replication not in the "Standby" state is changed to the "Standby" state.
  • Before performing a switchover, ensure that there is an asynchronous remote replication member in the "Standby" state and the two remote replication members at a site have the same primary and secondary attributes.
  • DR Star cannot be switched if its running status is "Invalid" or "Disable".

Example

Switch DR Star "200bc79b99520000".

admin:/>swap dr_star dr_star_id=200bc79b99520000 
WARNING: You are about to switch DR Star trio. 
This operation switches the status of two asynchronous remote replication members in the DR Star trio. Before performing this operation, check the standby synchronization mode of the DR Star trio. You are advised to perform the switchover in incremental synchronization mode. If the synchronization mode is full, the protection capacity at the size of a member LUN is required at the third site after the switchover. Ensure that the space of the third site is sufficient. 
Suggestion: Ensure that you have selected the correct DR Star trio.
