Chapter 3
Preparations
The left side of the window shows the current state of
the system with the existing RAID configuration, hard
disks, and Fibre Channel Interface Board represented
as icons (see the next section) in a hierarchical (tree)
structure.
Unused hard disks (Free HDD) are displayed as in the
following figure. The display shows where the hard
disks are installed.
In this example, the hard disk is the disk at position 0
in the Fibre Channel Storage Unit whose fibre channel
unit address is 1.
Hard disk numbers correspond to the disk status
indicator numbers (0 to 9) on the Fibre Channel
Storage Unit.
For explanations of icons, consult Help for the Disk Utility.
Note
Fibre channel unit address would not be displayed
correctly if the value is duplicated.
For details, see Section 2-3 “DMW-ST001 Fibre
Channel Storage Unit” (page 2-14).
Icons displayed in the Disk Utility main
window
The following icons are displayed on the left side of
the Disk Utility main window.
The workstation of this system.
The Fibre Channel Interface Board installed in this
system.
A fibre-channel port of the Fibre Channel Interface
Board.
A fibre channel (FC) loop.
(Blue)
A free hard disk drive, not yet connected to Windows.
Single disk drives and RAID drives are constructed
from free hard disk drives.
(Single disk drive, yellow)
(RAID 0, yellow)
A normal status RAID drive. Single disk drives are
logical drives constructed from free hard disk drives. A
RAID 0 drive is a logical drive constructed from two
or more free hard disk drives.
(Single disk drive, light yellow)
(RAID 0, light yellow)
A RAID drive which is not connected to Windows,
because you do not have access rights or because the
drive has just been constructed.
(Blue)
A used disk drive. A hard disk drive which constitutes
part of a RAID drive or which is currently in use.
However, its status is unstable for one of the following
reasons.
• One or more of the hard disk drives making up the
RAID drive was not recognized by the system. (In
this case, all of the hard disk drives in the RAID drive
have Used status.)
• One or more of the hard disk drives making up the
RAID drive is broken. (In this case, all of the hard
disk drives in the RAID drive have Used status.)
• One or more of the hard disk drives making up the
RAID drive has been disconnected from the DMW-
ST001. (In this case, all of the hard disk drives in the
RAID drive have Used status.)
• A Replace operation using a spare hard disk drive
was attempted, but the state of the RAID drive where
the operation was attempted did not allow it to
succeed.
(Dark brown)
A broken hard disk drive.
(Single disk drive, yellow)
(RAID 0, yellow)
A single disk drive or RAID drive that is undergoing
maintenance (Replace or Repair).
(Blue)
A free hard disk drive that is the target of a Replace
operation. When the Replace operation finishes, this
drive replaces the original drive.
