I built SMBC with two sets of A300 (ontap 9.9.1p9) The test encountered several problems: 1. When all interclusters of the source are disconnected, the IO of the business host stops. about 30s interruption 2. The business side is continuously writing, and the source is directly powered off, and the IO is interrupted for about 22s. After the source is started, the snapmirror relationship cannot be recovered and the status is broken; the error is: Failed to verify replication of SAN ALUA path configuration.
