Scenario 3: Disk Failure, Spare Disk Rebuild and Replacement of Failed Disk before completion of Spare Disk Rebuild

In a storage array if a Disk fails, then Disk Rebuild starts on the Spare Disk.

Let the primary Disk be 0_0_1 and the Spare Disk be 0_0_24.

Workflow

1. When Disk 0_0_1 fails, then rebuild on the spare Disk 0_0_24 begins.

2. The failed Disk 0_0_1 is fixed and replaced before the completion of rebuild on the Spare Disk 0_0_24. The rebuild on Spare Disk 0_0_24 continues till rebuild is complete.

3. Notifications statuses:

   • DiskFault event and Down problem for Disk 0_0_1 are cleared.

     • DiskRebuildEvent and DiskRebuild are generated for Spare Disk 0_0_24 and remain till rebuild is complete.

4. Disk Rebuild on Disk 0_0_1 starts only after the completion of Disk Rebuild on Spare Disk 0_0_24.

5. The notifications DiskRebuildEvent and DiskRebuild are generated for Disk 0_0_1.

6. When Disk Rebuild on Disk 0_0_1 is complete, all notifications are cleared.
