1.4.3 Easy of Use features

1.4.3.1 Instant Availability/Background Initialization
RAID 0 and RAID 1 volume set can be used immediately after the creation. But
the RAID 3, 5 and 6 volume sets must be initialized to generate the parity. In
the Normal Initialization, the initialization proceeds as a background task, the
volume set is fully accessible for system reads and writes. The operating sys-
tem can instantly access to the newly created arrays without requiring a reboot
and waiting the initialization complete. Furthermore, the RAID volume set is
also protected against a single disk failure while initialing. In Fast Initialization,
the initialization proceeds must be completed before the volume set ready for
system accesses.
1.4.3.2 Array Roaming
The RAID subsystem stores configuration information both in NVRAM and on
the disk drives It can protect the configuration settings in the case of a disk
drive or controller failure. Array roaming allows the administrators the ability to
move a completely raid set to another system without losing RAID configura-
tion and data on that raid set. If a server fails to work, the raid set disk drives
can be moved to another server and inserted in any order.
