Background Tasks
Background tasks are maintenance tasks that help maintain the integrity of
your drives and data. These tasks include
•
Initialization of units
•
Verification of units
•
Rebuilds when units have become degraded
•
Migration of an on-line RAID from one RAID configuration to another
•
Self-tests
You can set up your system so that these tasks occur as they are needed, or
you can create schedules so that they occur during non-peak times.
Background tasks can have an effect on performance, so using a schedule can
minimize the impact.

Although the migration of a unit is handled as a background task, initiating it
is similar to creating a new unit. For details, see “Changing An Existing
Configuration by Migrating” on page 120.
