User Manual

5.2.6 Activate Incomplete RAID Set

When Raid Set State is “

Normal

”, this means there is no failed disk drive.

When does a Raid Set State becomes “Incomplete”?

If the RAID subsystem is powered off and one disk drive is removed or has failed in
power off state, and when the subsystem is powered on, the Raid Set State will
change to “

Incomplete

”.

The Volume Set(s) associated with the Raid Set will not be visible and the failed
or removed disk will be shown as “

Missing

”. At the same time, the subsystem

will not detect the Volume Set(s); hence the volume(s) is/are not accessible.
