ASM failure groups

Edit online

IBM® Storage Protect Snapshot supports Oracle Automatic Storage Management (ASM) failure groups.

When the ASM database is configured with normal or high redundancy, the disk groups are composed of two or three failure groups. These groups can be on two or three respective storage device. IBM Storage Protect Snapshot creates a backup entirely within only one of the storage device.

If you use ASM failure groups, review these guidelines:
  • In setups where all failure groups are on one storage device, IBM Storage Protect Snapshot backs up all failure groups.
  • In setups where all failure groups are on different storage device, IBM Storage Protect Snapshot backs up all failure groups that are on the storage device that is configured for the current operation. For more information, see DEVICE_CLASS device.
  • IBM Storage Protect Snapshot does not split the failure groups on a remote system.
  • Failure group support does not require a backup server.
  • IBM Storage Protect Snapshot does not re-create failure groups when a restore operation is completed. You must add the failure groups manually to achieve the appropriate redundancy level.
