Rebuilding Units 5 If the degraded unit has more than one degraded drive (for example, a RAID 10 where both mirrored pairs each have a degraded drive), repeat steps 3 and 4. If rebuild scheduling is not enabled on the Scheduling page, the rebuild process begins almost immediately in the background. If rebuild scheduling is enabled, the unit will not start actively rebuilding until the next scheduled time. Note: If you need to cancel a rebuild, you can do so by using the Remove Drive link on the Maintenance page to remove the drive from the unit. Rebuilding Units through 3BM When a RAID unit becomes degraded, it is marked as such, and the drive(s) that failed are marked as Not In Use in the 3BM screens. Figure 71, shows an example of how a degraded RAID 5 unit appears in 3BM. Figure 71. Degraded RAID 5 Array to be Rebuilt You can start the rebuild of a degraded unit manually in 3BM, or you can let the system boot and allow the rebuild to take place automatically. www.3ware.com 191
