Overview
• Starting a Data Supervisor session
• Array components and their icons
• Components window
• Array Configuration window
This chapter describes the following:
- Starting and exiting a Data Supervisor session
- Array components and their icons
- Components window
- Array Configuration window
Subsequent chapters describe how to configure and monitor an array starting from the Components
window.
 |
NOTE:
This guide assumes that you are familiar with the windows
environment for your management station. |
|
NOTE:
Before starting a session, make sure that Data Agent
is running on the server with the array that you want to manage with the session. |
- Log in to either the management station as Administrator or someone who has administrative privileges.
- From the Windows NT taskbar, follow the path
Start � Programs � Dell OpenManage™
� PowerVault™ Manager � Data Supervisor
� Data Supervisor
The About Dell OpenManage™ Data Supervisor window shown next opens.
Figure 5-1. About Dell OpenManage™ Data Supervisor window
- In the About Dell OpenManage™ Data Supervisor window, click the OK button or wait
for the window to close automatically in 30 seconds.
The following Data Supervisor Query window opens:
Figure 5-2. Dell OpenManage™ Data Supervisor Query
- In the window specify the array that you want to manage by entering the following, and
then clicking the OK button:
hostname arrayname
where
hostname is the name of a server connected to the array.
arrayname is the device name of the LUN in the array that is the communication
path to the array. The format of this device name is
\\.\SCSIp:b:t:l where p
is the port for the host bus adapter; b is the fibre channel bus on the adapter; t
is the target ID of the SP; and l is the LUN number.
Data Supervisor tries to contact the server and array you specified. If it succeeds, it
opens the Components window. If it does not succeed, it displays an error message, and the
session is terminated. If this happens, make sure that
- Data Agent is running on its server, and was started by a user who was logged in as root
or with Administrative privileges.
- The array name is correct in the Data Agent configuration file on its server.
Continue to the "Array components and their icons" section to learn about
them.
To exit a Data Supervisor session
- From any Data Supervisor window with a menu bar, follow the menu path File � Exit.
A confirmation window opens.
- In the confirmation window, click the OK button.
A Fibre Channel array with Fibre Channel disks always contains one DPE enclosure. If it
is a rackmount array, it may also contain one or more DAE enclosures. If it is a deskside
array, it always contains one DPE enclosure, and may have one or more DAE enclosures
connected to it.
You manage an array by configuring it and monitoring its operation. You configure an
array by partitioning its memory and binding its disk modules into logical units (LUNs).
You monitor its operation by watching the appearance of various icons in the Data
Supervisor windows and examining status and statistics for the array and its components.
The icon for an enclosure consists of an image that represents the enclosure type and
the enclosure ID.
Enclosure icon images
The images for the different enclosure types are:
| Icon image |
Enclosure type |
 |
Rackmount DPE |
 |
Deskside DPE |
 |
Rackmount DAE |
The color of the image and the letter it may contain indicate the status (that is,
operational state) of the enclosure.
| Image Color |
Letter |
Health |
State of enclosure |
| Grey |
none |
Normal |
Operating normally. |
| Amber |
F |
Faulty |
Faulty, due to a failed CRU. |
Enclosure ID
The enclosure ID is a number, which is 0 for a DPE enclosure and the enclosure address
(EA) for a DAE enclosure. A DAE's enclosure address is set by switches on the DAE.
LUN icons
The icon for a LUN consists of an image that represents the LUN's type and a LUN ID.
LUN icon images
The image in a LUN icon varies with the type of LUN as follows:
| Icon image |
LUN type |
Icon image |
LUN type |
 |
RAID 0
Redundant individual access array |
 |
RAID 1
Mirrored pair |
 |
RAID 1/0
Mirrored RAID 0 group |

RAID 3
Parallel access array |
 |
RAID 5
Individual access array |
 |
Disk

Hot Spare

The color of image representing a disk module image and the letter it may contain
indicate the status (that is, operational state) of the LUN as follows:
| Image Color |
Letter |

State of LUN |
| Grey |
none |
Normal |
Operating normally. |
| Blue |
T |
Transitional |
Transitional, such as being
bound or incorporating a hot spare. |
| Amber |
F |
Faulty |
Faulted, due to a failed array
component or a breakdown in communication with the LUN. |
LUN ID
The LUN ID is the two-digit hexadecimal number that was assigned when the LUN was
bound. When a hot spare replaces a failed disk in a LUN, the LUN ID for the hot spare is
followed by numbers in parentheses that tell which disk in which LUN it is replacing. For
example, if a hot spare with LUN ID 09 is replacing disk 13 in LUN 04, its LUN ID and the
numbers in parentheses are 09 (04:13).
Each disk module slot in an array enclosure is represented by an icon. If the slot
contains a disk module, the icon consists of an image that represents a disk module. If
the slot is empty, the icon consists of an image that represents an empty disk slot.
Disk module images
The image for a disk module may or may not contain a LUN ID and a disk ID, as shown
below. The image may contain a LUN ID only if the disk module is bound into a LUN.
| Image |

Disk module that may or may not

Disk and LUN IDs
A disk ID is a decimal number that equals the enclosure address of the enclosure
containing the disk multiplied by 10 plus the number of the slot containing the disk. For
example, 13 is the disk ID for the disk module in slot 3 of a DAE with an enclosure
address of 1. The enclosure address is always 0 for a DPE; for a DAE, it is set by
enclosure (EA) switches on the DAE. The disk slots in a DPE or DAE are numbered 0 though
9.
For information on LUN IDs, see LUN ID.
By default, LUN and Disk IDs are hidden. You can hide or show either type of ID as
described below.
To show or hide Disk IDs
In the Array Configuration window (Array
Configuration window), select the menu option View � Show
Disk IDs.
To show or hide LUN IDs
In the Array Configuration window (Array
Configuration window), select the menu option View � Show
LUN IDs.

Figure 5-6. LUN selection area
The LUN selection area is where you select the LUNs on which you want to perform
operations. It has three sections: SP A Owned LUNs, SP B Owned LUNs, and Unowned LUNs. The
SP A Owned LUNs section contains an icon for each LUN currently owned by SP A. The SP B
Owned LUNs section contains an icon for each LUN currently owned by SP B. The Unowned LUNs
section contains an icon for any LUN not currently owned by an SP. A hot spare that is not
in use is an unowned LUN.
Selecting LUNs

or
Drag the cursor to create a box around the icons for the LUNs that you want to select.
A different colored box appears around each icon, indicating that you selected it.
Figure 5-7. Disk Field
The Disk Field shows the disk modules in the array, and which of these modules belong
to any selected LUNs. From it, you can display the Disk Information window for any disk
module. The field contains a disk module icon for each disk module in the array.
Identifying disk modules that comprise LUNs
To identify the disk modules comprising a LUN using LUN IDs
If no LUN IDs appear in any disk module icons, follow the menu path View � Show LUN IDs.
The LUN ID is visible in the icon for each disk module bound to a LUN.
To identify the disk modules comprising a LUN using color
Select the icon for the LUN in the LUN selection area.
The icon for the selected LUN and the icons for the disk modules that make up the
selected LUN are surrounded by boxes of the same color.
The status bar in the Array Configuration window contains an Auto Poll button, an Array
status button, and two fields that provide information.
Auto Poll button
The Auto Poll button lets you stop or start automatic polling for array status changes
at 60 second intervals. It functions the same way as the Auto Poll button in the
Components window status bar. For more information on this button, see Auto Poll button.
Array Status button
The Array Status button functions provides overall status of the array. It functions
the same way as the Array Status button in the Components window status bar. For more
information on this button, see Array Status button.
Information fields
The information fields provide the following information:
- Feedback about Data Supervisor operations, such as polling and parameter settings.
- Brief description of a LUN or array toolbar button when you position the cursor over the
button.
