The method of performing backup operation or replication operation on the transaction volume in scalable class is explained.
Figure 1.8 Combined operation with the scalable class
AdvancedCopy Manager does not support the scalable class. Therefore, the resource of AdvancedCopy Manager cannot be added to a scalable class.
When performing backup operation and replication operation to the transaction volume in scalable class, create the cluster service of new Storage Server transaction or Storage Management Server transaction. When cluster service in a scalable class consists of three or more nodes, create the Storage Server transaction in cascade topology. When cluster service in scalable class consists of 2 nodes, create the Storage Server transaction in mutual standby system.
The backup operation and replication operation are performed from the Storage Server transaction to the transaction volume in scalable class.
The above figure shows combined operation of userApplication in scalable class, and cluster service of Storage Server transaction. The backup operation for volume on transaction A is performed from the Storage Server transaction. The backup operation's information is managed in the Storage Server transaction.
Note
For notes on combined operation with transactions in scalable operation, see "Notes on cluster operation" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide".
