Software Installation and User’s Guide
ICP RAID Console
initialization build as “Non-destructive”, any data present on the drives being initialized is
destroyed. However, re-initialization of this RAID array is Non-destructive.
Figure 10-48. Progress Information: Non-destructive Array Build
10.4.1.2
Host Drive Statuses
The Select Host Drive screen displays a status for each configured host drive (for
example, the RAID 1 array drive in
Figure 10-47
has a status of
build)
. Definitions for all
states are provided below.
Idle State
The
idle
state is characterized by the fact that the redundant information of the disk array
has never been entirely created. The disk array is in this state after its first configuration
and until you quit ICPCON. Should an error occur while the array is in the
build
state, the
array returns to
idle
. The exception is that if during
build
mode the dedicated drive of
RAID 4 fails, the mode changes to
fail
.
Build State
After the disk array has been configured for the first time, it assumes the
build
state. While
the array is in the
build
state, redundancy information is calculated and stored to the hard
disks of the array.
Ready State
The disk array is fully operational when in the
ready
state. All redundant information is
present, for example, a hard disk can fail without impairing the functionality of the disk
array. This is the normal state of a disk array. The state
ready/expand
indicates that the
RAID level and/or capacity are currently migrated/expanded.
Fail State
The disk array changes to the
fail
state whenever a logical drive fails. Redundancy
information is still present, thus allowing the remaining hard disks to continue working.
This state should be eliminated as soon as possible by replacing the defective hard disk. If
