Automatically Rebuilding Degraded Array

This section discusses the following:

    Enabling Auto-Rebuild

    Auto-Rebuild with Hot Spare

    Auto-Rebuild with Hot Swap

Enabling Auto-Rebuild

Auto-Rebuild is disabled by default. You can enable Auto-Rebuild in the Property tab for the Adapter, as shown in Figure 1. After enabling Auto-Rebuild, select Modify to confirm the change.

Figure 1  Enabling Auto-Rebuild

Note: If your degraded array does not auto-rebuild even when a global/dedicated spare drive is available, verify that the spare drive is suitable for the array.

Auto-Rebuild with Hot Spare

When Auto-Rebuild is enabled and a suitable global/dedicated spare drive is available, MSU can automatically rebuild a virtual disk when it becomes degraded. To assign a physical disk as a global/dedicated spare drive, see sections Assigning Physical Disk as Global Spare Drive and Assigning Physical Disk as Dedicated Spare Drive.

Auto-Rebuild with Hot Swap

In the absence of a global/dedicated spare drive, you can auto-rebuild by hot-swapping another physical disk in the same location. MSU automatically rebuilds the array when it detects an online physical disk at that location.
