Managing arrays with Dell NNM SE: Dell OpenManage™ Data Supervisor, Event Monitor, and Integrator Installation and Operation Guide

Overview • Setting Up Dell NNM SE to start Data Administrator session of Data Supervisor • Monitoring array status • Starting Data Supervisor or Data Administrator from Dell NNM SE on the management station • Discovering new arrays from the management station

Overview

This chapter describes how to

• Setup Dell NNM SE to start a Data Administrator session instead of a Data Supervisor session
• Monitor arrays with Dell NNM SE
• Start Data Supervisor or Data Administrator from Dell NNM SE
• Discover new arrays with Dell NNM SE

Setting Up Dell NNM SE to start Data Administrator session of Data Supervisor

If Data Administrator is installed on the management station, you can set up Dell NNM SE to start Data Administrator instead of Data Supervisor by editing the
C:\OpenView\bin\ommgr.bat file as follows:

1. Change

cd:\Program Files\Dell OpenManage\PowerVault Manager\Data Supervisor\Data Supervisor

to

cd:\Program files\Dell OpenManage\PowerVault Manager\Data Administrator\Data Administrator

2. Change

start omspvr.exe %1 %2 %3 %4

to

start omadmin.exe %1 %2 %3 %4

Monitoring array status

After you have set up the servers connected to managed arrays and set up the management station, Dell NNM SE monitors the managed arrays on the servers that it discovered when it was started. Upon receiving an SNMP trap from an array, Dell NNM SE does the following:

• Puts an entry for the trap in its Error Events log
• Turns the color of the Event Categories icon red
• Changes the color of the icon for the server with the managed array reporting the status change
• Changes the color of the icon for the array reporting the status change from green to red

Opens Dell Diskarray Event window if Dell NNM SE is configured to display these windows.

To monitor arrays

1. If Dell NNM SE is configured to display CLARiiON_Diskarray Event windows, watch for these windows; otherwise, watch the Dell NNM SE Segment map for a blue server icon.

A sample CLARiiON_Diskarray Event window reporting status change follows.

Figure 4-1. Sample CLARiiON_Diskarray Event window



2. When you see a CLARiiON_Diskarry Event window or blue server icon, determine what status change caused the window or blue icon using either the Dell NNM SE event log (below) or "Data Supervisor or Data Administrator".

Using the event log to get status

1. If the Dell NNM SE Event Categories window is closed, double-click its icon.

The Event Categories window opens.

Figure 4-2. Sample Dell NNM SE Event Categories window

1. In the Event Categories window, click the button for the Error Events log.
2. In the Error Event Browser window, look for critical entries whose source is the server with the managed array that reported the status change.

The message portion of these entries has the following format:

Received CLARiiON event from "hostname", device \\.\SCSIp:b:t:l. (SPx) Message: "status_message""

where

"hostname"	is the name in quotation marks of the server with the managed array that reported the status change.
\\.\\\.\SCSIp:b:t:l	is the communications channel to the managed array on a server whose status changed. 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. l is the LUN number.
event_code	is the hexadecimal event code number for the type of event that caused the trap. This number is retrieved from the unsolicited event log in the SP of the managed array. See "Unsolicited event log messages" for the meaning of these codes.
(SPx)	is the SP in the array with the unsolicited event log from which the message was retrieved. x is either A or B.
"status_message"	consists of the time stamp in quotation marks when the event occurred and the message in quotation marks retrieved from the unsolicited event log in the SP of the managed array that caused the trap.

You may be able to find out more information about the managed array's component whose status changed using Data Supervisor or Data Administrator, as described in the next section. You can clear the status change indicators (color of the managed array icon and server icons) for a managed array as described in the "Clearing status change indicators" section.

Using Data Supervisor or Data Administrator to get status

To get status using Data Supervisor or Data Administrator

1. In the Dell NNM SE Segment map, double-click the blue server icon.

The server's submap opens, similar to the following.

Figure 4-3. Displaying the submap for server lucifer



If a managed array has reported a status change, its icon is red; otherwise, its icon is green.

2. In the server submap, double click the icon for the managed array whose status you want to determine.

A Data Supervisor session starts if you have not setup Dell NNM SE to start Data Administrator, and the Components window for the array opens. A Data Administrator session starts if you have setup Dell NNM SE to start Data Administrator, and the Array Management window opens.

3. Use Data Supervisor or Data Administrator to get information about the managed array's health and status.

For information about Data Supervisor, go to "Running Data Supervisor". For information on monitoring the array with Data Supervisor, go to "Monitoring an array". For information about Data Administrator and using it to monitor arrays, see the Dell OpenManage™ Data Administrator Installation and Operation Guide (P/N 8867C).

You can clear the status change indicators (color of the managed array's icon and server icons) for an array, as described in the next section.

Clearing status change indicators

1. In the Dell NNM SE Segment map, click the icon for the server whose managed array status indicators you want to clear.

The server's submap opens.

2. In the server's submap, select the icon for the managed array whose status indicator you want to clear.
3. Follow the Dell NNM SE menu path

Tools � Dell � Disk Array � Clear Status

The color of the selected managed array icon changes from red to green. If all the managed array icons on the submap are green, the color of the corresponding server icon changes from red to green on the Segment map.

Starting Data Supervisor or Data Administrator from Dell NNM SE on the management station

1. In the Dell NNM SE Segment map, double-click the icon for the server whose managed arrays you want to configure or manage using Data Supervisor or Data Administrator.

The submap for the server opens, similar to the sample in Figure 4-3.

2. In the server submap, double-click the icon for the managed array that you want to configure or manage using Data Supervisor or Data Administrator.

A Data Supervisor session starts if you have not setup Dell NNM SE to start Data Administrator, and the Components window for the array opens. The rest of the chapters in this guide describe Data Supervisor windows and how to use them to configure and manage arrays.

A Data Administrator session starts if you have set up Dell NNM SE to start Data Administrator, and the Array Management window opens. For information on how to use Data Administrator to configure and manage arrays, see the Dell OpenManage™ Data Administrator Installation and Operation Guide (P/N 8867C).

Discovering new arrays from the management station

If you add a server with arrays to the network, or add an array to a server already on the network, you can have Dell NNM SE discover these arrays so they become managed arrays without your restarting Dell NNM SE.

To have Dell NNM SE discover a new array

1. In the Dell NNM SE Segment map, click icon for the server connected to the new arrays that you want Dell NNM SE to discover.
2. Follow the Dell NNM SE menu path

Tools � Dell � Disk Array � Discover Agents

A window opens stating that the selected host is being checked for arrays. Any new arrays that Dell NNM SE finds will appear on the submap as a managed array for the selected host.
