Storage Cluster function switches over to the components in a standby system from the components in an active system transparently from external environments. The storage used as an active system is called "Primary Storage" and the storage used as a standby system is called "Secondary Storage".
In the existing operation, data must be kept equivalency maintenance state in an environment in which REC Paths are configured between the Primary Storage and the Secondary Storage, and if the Primary Storage stops, failover to the Secondary Storage must be performed in the following steps:
Change physical connections to the Secondary Storage and zoning configuration.
Re-acknowledge volumes by restarting business server.
Using the Storage Cluster function can save the time and steps spent in this work and realize transparent failover.
