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 “To verify a unit through 3BM” on page 166.
• 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.
• Initializing. The unit is in the process of writing to all of the disks in the
unit in order to make the array fault tolerant. For more information, see
“About Initialization” on page 158.
• Initializing-Paused. The unit is set to initialize, however scheduling is
enabled and the present time is not during a scheduled timeslot.
Initializing will start at the next scheduled time slot. Initialization is also
paused for up to ten minutes after a reboot, even during a scheduled
timeslot.
• Verifying. The unit is in the process of ensuring that the parity data of a
redundant unit is valid. For more information, see “About Verification”
on page 162.
• Verify-Paused. The unit is set to verify, however, scheduling is enabled,
and the present time is not during a scheduled timeslot. Verification will
start at the next scheduled time slot.
• Migrating. The unit is in the process of being reconfigured while it is
online. Migration can be used to change the RAID level, to expand the
capacity by adding additional drives, or to change the stripe size. For
more information, see “Changing An Existing Configuration by
Migrating” on page 128.
