Checking Unit and Drive Status

63

Enclosure LED Status Indicators

The LEDs on your enclosure also provide status information about your 
drives and units.

                                      

Unit Statuses

The following is a list of unit statuses you may see in 3DM:

 The unit is optimal and is functioning normally.

 The unit is in the process of writing data to a newly added 

disk in a redundant unit, in order to restore the unit to an optimal state. 
The unit is not fully fault tolerant until the rebuilding is complete. For 
more information, see “Rebuilding Units” on page 73.

 The unit is set to rebuild, however scheduling is 

enabled, and the present time is not during a scheduled timeslot. 
Rebuilding will start at the next scheduled time slot. Rebuilds are also 
paused for up to ten minutes after a reboot, even during a scheduled 
timeslot.
