The database data of a hospital's HIS system is stored in Huawei's all-flash storage. To ensure business reliability, the hospital has configured a disaster recovery host for this business in the branch data center and configured asynchronous remote storage for storage. The hospital now plans to conduct a disaster recovery test on the business system, requiring II T engineers to split the relevant remote pairs, cancel the slave resource protection, and then map the slave LUN to the disaster recovery host for read and write testing.
