Unit Statuses

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

•OK. The unit is optimal and is functioning normally.

•Rebuilding. 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.

•Rebuild-Paused.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.
