Support of Oracle Automatic Storage Management failure groups

Oracle ASM organizes data in disk groups that consist of a collection of disk drives that are in the same loop as configured by the storage subsystem.IBM® Storage Protect Snapshot uses an ASM instance to map these disk groups to physical disks. Each disk group can have multiple failure groups that are redundant copies of each other. These failure groups can be used as a technique to mirror storage volumes.

To use this technique, define disk groups with normal redundancy that are composed of two failure groups, and place the volumes for each of the failure groups on a dedicated storage cluster. Alternatively, define disk groups with high redundancy that are composed of three failure groups. Although the default Oracle System ID (SID) for the ASM instance is +ASM, other SIDs are supported.
