Reverse the role of all volume groups on the system that is still in normal operation (the failover system). Recovering from Disaster for 1-to-1 Configurationsįor the remote copy failover, recover and restore operation there are defined steps involved which need to followed as below.

After another 200 seconds, the system marks the targets as failed.

After 60 seconds, the system marks the sending links as down.

When a failure occurs on systems with asynchronous periodic mode volume groups such that all links between the systems are broken, the following actions occur: System Information during Failover for 1-to-1 ConfigurationsĪsynchronous Periodic Mode for 1-to-1 Configurations Below figure illustrates a bidirectional 1-to-1 remote-copy configuration.

Each storage system in the pair plays only one role: one system is the primary system, and one system is the backup system.Ī bidirectional 1-to-1 remote-copy configuration is composed of one remote-copy pair.Each storage system in the pair functions as both the primary and backup system and each system contains both primary and secondary volume groups.Įach system provides backup for the other, according to the direction of replication specified for each volume group. Expert on HPE 3PAR, HPE StoreOnce, HP EVA Storage, HP MSA/P2000, LHN and many other HPE products IntroductionĪ unidirectional 1-to-1 remote-copy configuration is composed of one remote-copy pair.
