ASM in a DS8000 environment

For IBM® System Storage® DS8000® environments, IBM Storage Protect Snapshot does not use FlashCopy® consistency groups when a FlashCopy backup is created. All table space files must be on a single disk group. There is no consistency across multiple LUNs on this storage system.

Ensure that all table space files are on a single disk group on DS8000 system. In addition, verify that the disk group contains exactly one LUN on the DS8000. IBM Storage Protect Snapshot does not support databases that are distributed across multiple storage clusters. There is one exception to this statement, and that is in environments where failure groups are used in a manner where every storage cluster contains a complete image of the databases.
