On-Demand Array Synchronization
To synchronize an Array immediately, do the following:
1. In Tree View, right-click on the icon
of the array
you want to synchronize.
2. Select Synchronize from the popup menu.
OR click the Synchronize Array button
in the
Toolbar.
While the Array is synchronizing, it is still available to read and write data. If
the beeper is enabled, it will beep slowly during this process.
To turn the beeper on or off, right-click on the Controller icon
or the
Enclosure icon
in Tree View and check or uncheck Beeper in the popup
menu.
Tree View and Information View display the progress.
Figure 5-19. Synchronization in progress (left) and completed (right).
When Synchronization is complete Tree View returns to normal and
Information View displays Functional.
Rebuild an Array
Rebuilding is the process of restoring redundancy to a RAID 1, 0+1, 3 or 5
after one of its drives has failed. When the replacement drive has been
installed, the RAID can read and write data but there is no redundancy until
the RAID has been rebuilt, that is, the new drive receives all the data and
parity of the original.
When a drive fails for any reason, the Array goes Critical. This condition is
noted when you select the Array Critical icon
in Tree View. The RAID
alarm beeps quickly to call your attention to the condition.
