Degraded Virtual
Disk/Array
A fault-tolerant virtual disk/array becomes degraded when one or
more member physical disks fail. In this state, the fault tolerance of the
degraded virtual disk/array is compromised to the extent determined
by the RAID level and number of failed member physical disks.
Rebuild the virtual disk/array to ensure continued and maximum fault
tolerance.

Erase Foreign
Configuration
Erase Foreign Configuration erases the RAID configuration metadata
on a foreign virtual disk. This is useful when using a foreign physical
disk in a new virtual disk.
Note: If the foreign physical disk was originally part of another virtual disk, erasing
RAID configuration data might damage that virtual disk, depending on the virtual disk’s
fault tolerance capabilities.
Event Logs Refers to the Event Logs pane in the Marvell RAID Utility.
Fast Initialization In this mode, MSU erases the Master Boot Record (MBR) in all
physical disks constituting the virtual disk. This is a destructive
process that erases all data on the virtual disk.
Note: Fast Initialization is available only when creating a virtual disk, except for
RAID-On-Chip Controllers (ROCs).

Fault Tolerance Refers to the ability of a virtual disk to remain operational even when
one or more member physical disks fail. The extent of fault tolerance
is determined by the RAID level of the virtual disk.
