4-6 Manual Rebuild

4.2 Manual Rebuild

All Galaxy’s arrays support hot-spares. Spare drives automatically

join a degraded logical drive, and hence rebuild is automatically

handled.

The manual Rebuild function applies in the following circumstances:

1. When a member drive fails in a configuration without spare

drives. If there are no Dedicated, Global, or Enclosure Spare

drives, rebuild must be manually initiated.

2. A replacement drive will not be recognized by firmware if

there is no drive check algorithms, e.g., period drive check

time; and before host I/Os are distributed to the logical drive.

WARNING!

Manual rebuild requires that a failed drive is properly replaced by a

replacement known to be “good.” Make sure you do not replace the

wrong drive.

Having one failed drive and a drive mistakenly

removed = failing two drives. Failing two members in a RAID1/3/5

logical drive can destroy all data stored on it.

Step 1. From the navigation panel, click on the “Rebuild” link

to inaugurate the Rebuild screen.

Step 2. Click on the APPLY button to start the rebuild

process. The rebuild progress will be indicated by a

gauge bar and a percentage count.

On SAS or SATA drive channels, disk drives are

regularly polled. A replacement drive is often brought

online automatically, and you may not need to

rebuild a logical drive.
