METHOD AND APPARATUS FOR AVOIDING PERFORMANCE DECREASE IN HIGH AVAILABILITY CONFIGURATION

摘要

Example implementations described herein are directed to a first storage system that provides a first volume with an identifier to a server. The first volume is communicatively coupled to the server through a first path with a first status, which can be active or passive. There is a second storage system that provides a second volume with the same identifier to the server. The second volume is communicatively coupled to the server through a second path with a second status, which can be active or passive. The first storage system sends a first instruction to the server to change the second status from active to passive and sends a second instruction to the second storage system to start executing a function, which accesses the second volume.

主权项

1. A computer system, comprising:
a server; a first storage system including:
a plurality of first storage devices, anda first controller which provides a first volume with an identifier to the server, the first volume corresponding to a storage area of the plurality of first storage devices, and the first volume is communicatively coupled to the server through a first path with a first status, which is active; and a second storage system including;
a plurality of second storage devices, anda second controller which provides a second volume with another identifier same as the identifier of the first volume to the server, the second volume corresponding to a storage area of the plurality of second storage devices, and the second volume is communicatively coupled to the server through a second path with a second status, which is active; wherein the second controller is configured to:
change the second status of the second path from active to passive; andstart executing a function on the second volume after changing the second status.
