Note
1. Once the “Expand Raid Set” process has started, user can not
stop it. The process must be completed.
2. If a disk drive fails during RAID set expansion and a hot spare is
available, an auto rebuild operation will occur after the RAID set
expansion completes.
3. RAID 30/50/60 doesn't support the "Expand Raid Set".
4. RAID set expansion is a quite critical process, we strongly
recommend customer backup data before expand. Unexpected
accident may cause serious data corruption.
5.5.2.3.1 Migrating
Migration occurs when a disk is added to a RAID set. Migrating state is
displayed in the RAID state area of “The Raid Set Information” screen when a
disk is being added to a RAID set. Migrating state is also displayed in the
associated volume state area of the “Volume Set Information” which belongs
this RAID set.
5.5.2.4 Offline Raid Set
This function is for customer being able to unmount and remount a multi-disk
volume. All Hdds of the selected RAID set will be put into offline state and spun
down and fault LED will be in fast blinking mode. User can remove those Hdds
and insert those Hdds on the others controller empty slots without needing
power down the controller to perform the online array roaming.
