Techniques for lif placement in san storage cluster synchronous disaster recovery

A method executed by one or more processors, comprising:

• during switchover operation where one or more destination virtual servers of a secondary cluster are serving data in place of one or more source virtual servers of a primary cluster that failed, performing a check to determine whether a pre-requisite for initiating a switchback phase is satisfied;
• in response to the pre-requisite being satisfied, initiating the switchback phase to switch back to the primary cluster for serving the data;
• and
• during the switchback phase, populating volume and logical unit number configuration at the primary cluster for the one or more source virtual servers and restarting the one or more source virtual servers for serving the data.

A computing device comprising:

• a memory comprising machine executable code for performing a method;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to:
• during switchover operation where one or more destination virtual servers of a secondary cluster are serving data in place of one or more source virtual servers of a primary cluster that failed, perform a check to determine whether a pre-requisite for initiating a switchback phase is satisfied;
• in response to the pre-requisite being satisfied, initiate the switchback phase to switch back to the primary cluster for serving the data;
• and
• during the switchback phase, populate volume and logical unit number configuration at the primary cluster for the one or more source virtual servers and restart the one or more source virtual servers for serving the data.
