the permissions on these files, refer to the Release Notice for Data Administrator for
information on what the permissions should be. |
What next?
Continue to the next section, "Starting a Data Administrator session."
Before you use Data Administrator, someone must have performed the following tasks:
| Task |
Described in |
Set up the servers whose
arrays you want to manage. |
The documentation supplied with
the server |
| Install the arrays on the servers. |
Dell PowerVault Rackmount
Storage System Installation and Service Guide (P/N 5867C) or Dell
PowerVault 651F Deskside Storage System Installation and Service Guide
(P/N 3867C) |
Install and configure Data
Agent on the servers. |
Dell OpenManage Data
Agent Installation and Operation Guide (P/N 3967C) |
Any user can run a Data Administrator session from any management station on which it
is installed, and can use it to monitor the array. Only authorized users can use Data
Administrator to configure or reconfigure an array. A user is authorized if the Data
Agent on the server contains an entry for the user, as described in the Dell
OpenManage Data Agent for NT and Integrator Installation and Operation Guide
(P/N 3967C).
 |
CAUTION:
The agent allows more than one Data
Administrator session to access the same array at the same time. As a result, two
authorized users are able to configure or reconfigure the same array at the same
time. |
Before Data Administrator opens its Storage Management window, it must know which servers
have arrays that you want to manage during the session. You can specify these servers in one
of the following ways:
- Put the server hostnames in a .hosts file in your home directory.
- Put the server hostnames in the file pointed to by the optional environmental variable
RAID_ARRAY_HOSTS, and let Data Administrator use this file.
- Use Data Administrator's Host Administration window, which Data Administrator opens
if the previous two options are not available.
To start a Data Administrator session
 |
NOTE:
Before starting a session, make sure that
Data Agent is running on all servers with arrays 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 Adminstrator
� Data Administrator
The following About Dell OpenManage Data Administrator window opens.
Figure 2-2. About Dell OpenManage Data Administrator window

- In the About Dell OpenManage Data Administrator window, click the OK button
or wait for the window to close automatically in 30 seconds.
Data Administrator looks first in your home directory for a .hosts file that contains
the hostnames of servers with arrays to manage. If such a file exists, Data Administrator tries
to extract hostnames from this file. If it succeeds, it contacts each server in the file and
displays a list of the arrays connected to the server. When it has contacted all the servers,
it opens the Storage Management window.
If the .hosts file does not exist, it asks if you want to use the file pointed
to by the optional RAID_ARRAY_HOSTS environmental variable. If the variable does
not exist, it opens the Host Administration window. If the variable exists, it
tries to extract the hostnames of servers from the file pointed to by the variable. If
it does not succeed, it opens the Host Administration window. If it succeeds, it
contacts each server in the file and displays a list of the arrays connected to the
server. When it has contacted all the servers, it opens the Storage Management window.
What next?
If the Data Administrator window opens, go to the
"Arrays, LUNs, disk modules, and their icons"
section to learn about them.
If the Host Administration window opens, go to the next section, "Using the Host
Administration window".
To exit a Data Administrator session
- From any Data Administrator window with a menu bar, follow the menu path File
� Exit.
A confirmation window opens.
- In the confirmation window, click the OK button.
Figure 2-3. Host Administration window

The Host Administration window opens when you start a Data Administrator session if no
server hostnames are in the .hosts file or in the file pointed to by the optional
RAID_ARRAY_HOSTS environment variable if you tell Data Administrator to use this
variable. In this situation, the list of host identifiers in the window is empty. You can
open the window during a Data Administrator session from the Storage Management window by
following the menu path File � Select Hosts. In this situation,
the list contains the hostnames of the servers with currently managed arrays. You can add
or remove server hostnames from this list. Servers on this list are called managed
servers.
To add a server to the list
- For each server that you want to add, follow these steps:
- In the Host Identifier field, enter the server hostname or IP address.
- Click the Add button.
The hostname appears in the list of servers below the Host Identifier field.
- When the list contains all the hostnames or IP addresses for the servers whose
arrays you want to manage, click the OK button.
A window opens asking if you want to save the new host list in the .host file in
your home directory. You should save the list if it contains only servers with arrays you
will manage in the future. Do not save the list if it contains servers that you will
manage in the current Data Administrator session only.
 |
NOTE:
If you save the host list, it is written to the
.hosts file and never to the file pointed to by the optional RAID_ARRAY_HOSTS
environment variable. |
- In the window, click the Yes button to save the new server list to the .hosts
file; otherwise, click the No button.
 |
NOTE:
If you add the wrong name, you can remove
it from the list, as described in the procedure that follows, and then add the correct
name. |
Data Administrator creates an icon for each array that it finds connected to each server
whose hostname you added to the list, provided that the icon does not already exist. Data
Administrator creates only one icon for each array, no matter how many servers are
connected to the array.
Data Administrator displays these icons in the array selection area of its Storage Management
window (see "Array selection area"). Since Data
Administrator creates only one icon for each array, just one icon is displayed for an array
connected to two servers.
 |
NOTE:
If Data Administrator cannot communicate with
a server you added to the list, it displays an error message. |
To remove a server from the list
- For each server you want to remove, follow these steps:
- Select the server's hostname or IP address in the list.
The selected hostname or IP address appears in the Host Identifier field.
- Click the Remove button.
A confirmation window opens.
- In the window; click the Yes button to confirm the removal.
The hostname disappears from the list of servers below the field.
- When the list contains only the hostnames or IP address for the desired servers,
click the OK button.
A window opens that asks if you want to save the new host list in the .hosts file
in your home directory. You should save the list if it contains only servers with arrays
you will manage in future Data Administrator sessions. Do not save the list if it contains
servers that you will manage in the current Data Administrator session only.
 |
NOTE:
If you save the host list, it is written to
the .hosts file and never to the file pointed to by the RAID_ARRAY_HOSTS
variable. |
- In the window, click the Yes button to save the new server list to the .hosts
file; otherwise, click the No button.
Data Administrator removes the icon for each array on each server that you removed, provided
that the array is not connected to another server that is still on the list. It removes them
from the array selection area of its Storage Management window (see
"Array selection area").
What next?
Continue to the next section to learn about arrays, logical units (LUNs), disk modules,
and their icons.
For a Data Administrator, an array is accessible, inaccessible, or unsupported.
If this Data Administrator session can communicate with an array, the array is accessible.
If this session of Data Administrator has never been able to communicate with an array, it
is inaccessible. An array can be inaccessible for any of these reasons:
- Data Agent is not running on its server.
- Data Agent on its server was started by a user who was not logged in as root or with
Administrative privileges.
- The array's name is wrong in the Data Agent configuration file on its server.
An array is unsupported if its device entry in the Data Agent configuration file on its
server is for a device that Data Administrator does not support. An internal disk on the
server is such a device, or an array with SCSI disks.
You can manage only accessible arrays. 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 Administrator windows and examining status and statistics for arrays, array
components, and LUNs.
The icon for an array consists of an image that represents the array type and the
array name.
Array icon images
The image varies depending on whether the array is accessible, inaccessible, or unsupported,
as follows:
Table 2-1. Array icon image types
| Image |
Array type |
 |
Accessible Fibre Channel array
that consists of 1 DPE enclosure and 0-11 DAE enclosures |
 |
Inaccessible array |
 |
Unsupported array |
The color of the image representing an accessible array and the letter it contains indicate
the state of the array it represents as follows:
Table 2-2. Meaning of array icon images
| Image Color |
Letter |
Operation |
State of array |
| Grey |
none |
Normal |
Operating normally. |
| Amber |
F |
Faulty |
Faulty, due to a failed component
or a breakdown in communication with the array. |
Array names
The default name for an array has the following format:
hostnamedevice_name
where
| hostname |
is the name of a server connected to the array. |
| device_name |
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. You can give the array a custom
name. |
To assign a custom name to an array
- Select the icon for the array whose name you want to change.
- Do one of the following:
Either
Click the Name Array button on the toolbar in the
Storage Management window
Or
From the menu bar in the Storage Management window,
select the menu option Array � Name.
 |
NOTE:
Changing the name does not affect the Data
Agent configuration file. |
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:
Table 2-3. LUN icon image types
| 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 Individual unit |
 |
Hot Spare Global hot spare |
|
|
The color of image representing a LUN and the letter it may contain indicate the status
(that is, operational state) of the LUN as follows:
Table 2-4. Meaning of LUN icon images
| Image Color |

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).
Disk module icons and empty disk module slot icons
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.
Table 2-5. Disk module icon image types
| Image |

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, and 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.
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, select the
menu option View � Show Disk IDs.
To show or hide LUN IDs
In the Array Configuration window, select the
menu option View � Show Disk IDs.
