AMCC 720-0138-00 manual To rebuild a unit through 3DM, Selecting a Drive when Rebuilding

Chapter 6. Maintaining Units

Note: If a rebuild fails, check the Alarms page for the reason. If there was an ECC error on the source disk, you can force the rebuild to continue by checking the Overwrite ECC Error policy on the Controller Settings page in 3DM and then running Rebuild again. This will cause uncorrectable blocks to be rewritten, but the data may be incorrect. It is recommended that you execute a file system check when the rebuild completes. On Mac OS X, you can do this using the First Aid tab in the Disk Utility—select the disk on the left and then click Verify Disk. If verification encounters problems, you can then use the Repair Disk option on the same screen.

To rebuild a unit through 3DM

1If necessary, add a new drive to replace the failed drive. (For details, see “Adding a Drive” on page 58.)

2In 3DM, choose Management > Maintenance.

3In the Unit Maintenance section of the Maintenance page, select the degraded unit and click the Rebuild Unit button.

4When a dialog box displays available drives, select the drive you want to replace the failed drive and click OK.

Figure 28. Selecting a Drive when Rebuilding

5If the degraded unit has more than one failed drive (for example, a RAID 10 where both mirrored pairs each have a failed drive), repeat step 3 and step 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.
