Running DAE-MON: Dell OpenManage™ DAE-MON Installation and Operation Guide

Overview • Starting a DAE-MON session • Daemon window • Equipment window • Monitoring DAE operation • Exiting DAE-MON

Overview

Any user that can log on to a Windows NT server as Administrator or someone with administrative privileges can start a DAE-MON session on the server and monitor the operation of the server's DAEs. This section describes the Daemon window and Equipment window, and explains how to perform the following tasks:

• Start a DAE-MON session
• Monitor DAE operation using the DAEmon and Equipment windows (see Monitoring DAE operation)
• Exit a DAE-MON session (see Exiting DAE-MON)

NOTE: DAE-MON uses Microsoft 32-bit Windows on the Windows NT server. This guide assumes that you are familiar with the windows environment for your server.

Starting a DAE-MON session

When you start DAE-MON, it creates an icon for each DAE that Windows NT found the last time you rebooted the server. If you have added DAEs since then, you must reboot the server for Windows NT to find the additional DAEs.

To start a DAE-MON session

1. Log on to the server as Administrator or someone who has administrative privileges.
2. From the Windows NT taskbar, follow the path

Start � Programs � Dell OpenManage™ � PowerVault™ Manager � DAEmon � DAEmon

The following DAE-MON information window opens.

Figure 3-1. Dell OpenManage™ DAE-MON information window


3. In the Dell OpenManage™ DAE-MON information window, click the OK button.

The Daemon window opens.

Daemon window

The Daemon window opens when you start a DAE-MON session. You use this window to perform the following operations:

• Display the Equipment windows for selected DAEs so you can monitor the status of their customer-replaceable units (CRUs)
• Poll selected DAEs for status changes
• Disable automatic polling or specify the time between automatic polls of DAEs

The Daemon window consists of these components:

• Menu bar
• Array selection area
• Status bar

Figure 3-2. Sample Daemon window

Menu bar

From the menu bar in the Daemon window you can access these menus: File, Array, Options, and View.

Table 3-1. File menu

Table 3-2. Array menu

Table 3-3. Options menu

Table 3-4. View menu

Array selection area

Figure 3-3. Sample array selection area in the Daemon window

You use the array selection area in the Daemon window to select the DAEs on which to perform operations. This area contains an array icon for each DAE that DAE-MON finds when you start it. An array icon consists of the graphical representation of the DAE and its enclosure address, which is the setting of the enclosure address (EA) switch on the front of the DAE.

NOTE: For information on the proper setting of the EA switch, refer to the DAE's installation and service guide. (The installation and service guide for a rackmount DAE is the Dell™ PowerVault™ 630F and 250F Rackmount Storage Systems Installation and Service Guide (P/N 4867C); and for a deskside DAE, it is the Dell™ PowerVault™ 251F Deskside Storage System Installation and Service Guide (P/N 2867C).)

The DAEs with array icons in the array selection area are the managed DAEs. The graphic in the array icon varies depending on whether the DAE is accessible or not, as shown below.

Table 3-5. Meaning of the array icon graphics

When you start DAE-MON, it finds all accessible DAEs (that is, DAEs it can communicate with), and displays the appropriate array icon for each of them. DAE-MON does not display an icon for a DAE that is inaccessible at start up. If a DAE that is accessible at start up becomes inaccessible, DAE-MON replaces its array icon with the inaccessible array icon.

DAE-MON cannot communicate with a DAE when any of the following conditions occur:

• The DAE's enclosure address is used by another DAE on the Fibre Channel loop. The DAE becomes accessible when you power down the DAE, set its EA switch to a unique address, and power it up again.
• The disk that DAE-MON is using to communicate with the DAE is faulted or removed. The DAE becomes accessible when you replace or reinstall the disk or you restart DAE-MON.

NOTE: DAE-MON requires at least one disk in slots 0 through 3 to communicate with the DAE.

• The link control card (LCC) that DAE-MON is using to communicate with the DAE or that LCC's cabling is faulty or removed. The DAE becomes accessible when you replace or reinstall the LCC or the cabling.

You select a DAE by clicking its array icon. You select multiple DAEs by holding down the Shift key and clicking the icon for each DAE you want to select. When you select a DAE, a box appears around it.

The color of the array icon for an accessible DAE indicates the state of the DAE as follows:

Table 3-6. Meaning of the array icon colors

When DAE-MON polls a DAE, it updates the color of its array icon to reflect the DAE's current state.

Status bar

The status bar in the Daemon window provides the following types of information:

• Overall status of the managed DAEs
• Polling status

The status bar contains an Array Status button, a status field, and a Polling Interval field.

Array Status button

Figure 3-4. Meanings of Array Status button

The Array Status button provides a visual indication of the overall status of all managed DAEs. If DAE-MON does not detect any failures in any managed DAEs and it can access all managed DAEs, the Array Status button is grey and contains the word Normal. If DAE-MON detects a failure in any DAE or any DAE is inaccessible, the Array Status button is amber and contains the word Fault. Clicking the Array Status button displays an information window that states that no arrays have faults or provides information window that states that no accays have faults or provides information about what caused each faulted array to fail or tells which DAEs are inaccessible.

Status field

When DAE-MON polls a DAE, the status field displays the enclosure address of the DAE.

Polling Interval field

The Polling Interval field on the status bar in the Daemon window displays the current setting of the automatic polling interval parameter, which is either "Disabled" or 5, 10, 30, or 45 seconds or 1 to 2400 minutes. "Disabled" indicates that automatic polling will not occur. A number in this field specifies the number of seconds or minutes between automatic polls of the managed DAEs.

Equipment window

The Equipment window opens when you double-click an array icon in the Daemon window. You use the Equipment window to perform the following operations:

• View the status of the CRUs that make up the selected DAEs
• Poll the selected DAEs for status changes

The Equipment window consists of these components:

• Title bar
• Menu bar
• Chassis and CRU drawings
• Status bar

Chassis and CRU drawings

The chassis and CRU drawings in the Equipment window are physical renditions of the DAE chassis and the CRUs it can contain: disk modules, LCCs, power supplies, and drive fan pack. Each CRU drawing is an icon. The drawings vary depending on whether the selected DAE is a deskside or rackmount DAE. Sample drawings for a deskside and rackmount chassis follow. These drawings show the locations of the CRU icons. When you move the cursor on one of these icons, a description of the CRU appears in the status bar

Figure 3-7. Sample chassis and CRU drawings for a deskside DAE

Figure 3-8. Sample chassis and CRU drawings for a rackmount DAE

The color of each CRU icon indicates the state of the CRU it represents, as described in the "Monitoring a DAE operation" section on The color of each CRU icon in the Equipment window for a DAE indicates the operational state of the CRU as follows:.

When DAE-MON polls a DAE, it updates the color of each CRU icon to reflect the CRU's current state.

When you click a CRU icon, a status window opens that contains status information for the CRU.

Status bar

The status bar in the Equipment window provides the following types of information:

• Overall status of the managed DAEs
• Polling status and the CRU name

The status bar contains an Array Status button and a status field.

Array Status button

Figure 3-9. Meanings of Array Status button

The Array Status button on the status bar in the Equipment window functions the same way as the Array Status button in the Daemon window. It provides a visual indication of the overall status of all managed DAEs. If DAE-MON does not detect any failures in any managed DAEs and it can access all managed DAEs, the Array Status button is grey and contains the word Normal. If DAE-MON detects a failure in any array or any array is inaccessible, the Array Status button is amber and contains the word Fault. Clicking the Allay Status button displays an information window that states that no allays have faults of provides information about what caused each faulted allay to fail,as well as tells which DAEs are inaccessible.

Status field

When you position the cursor on a CRU icon, the Status field displays a description of the CRU. When DAE-MON polls a DAE, the Status field displays the device name of the DAE.

Monitoring DAE operation

You monitor the operation of a DAE using the DAEmon and Equipment windows. This section describes how these windows display information about the operation of the DAE and how to use them to monitor the operation of a DAE.

How the windows display information about DAE operation

The Daemon window shows the operational state of the managed DAEs at a glance. The Equipment window shows the operational state of the selected DAE's CRUs at a glance. The Array Status button in both windows shows overall operational state of the managed DAEs.

The graphic in the array icon for a DAE tells you if the DAE is accessible or inaccessible as follows:

Table 3-10. Icons for accessible and inaccessible DAEs

Accessible DAE	Inaccessible DAE

The color of the array icon for an accessible DAE in the Daemon window indicates the operational state of the DAE as follows:

Table 3-11. Meaning of the array icon colors

The color of each CRU icon in the Equipment window for a DAE indicates the operational state of the CRU as follows:

Table 3-12. Meaning of the CRU icon colors

Monitoring the operation of a DAE

This section describes a general procedure you can use to detect and isolate problems that may arise with a DAE. You may want to vary the procedure to better suit your environment.

To monitor the operation of a DAE

Start DAE-MON

The Daemon window opens.

In the Daemon window, look for an array icon for each DAE on the Fibre Channel loop.

If an array icon does not appear for a DAE, the DAE is inaccessible, and you should refer to the DAE's installation and service guide one for the correct way to install and start a DAE. (The installation and service guide for a rackmount DAE is the Dell™ PowerVault™ 630F and 250F Rackmount Storage Systems Installation and Service Guide (P/N 4867C); and for a deskside DAE, it is the Dell™ PowerVault™ 251F Deskside Storage System Installation and Service Guide (P/N 2867C).)

Select the automatic polling interval as follows:

From the Daemon window, follow this menu path:

Options � Automatic Polling Interval

1. From the submenu that appears, select the number of seconds or minutes that you want between polls or select Other to specify the number of minutes you want.

NOTE: We recommend you use a polling interval of 15 to 30 seconds.

At any time you can manually update the status information for one or all DAE-MON icons from the Daemon window by following these menu paths: Array � Select or Array � Select All, and then Array � Poll.

In the Daemon window, periodically look at the Array Status button.

If the Array Status button contains the word Normal - All managed DAEs are operating normally. If you want to determine the state of the CRUs for a specific managed DAE, follow these steps:

In the Daemon window, double-click the icon for the DAE whose CRU states you want to view.

The Equipment window for the DAE opens.

1. Check the color of the icons for each CRU (disk modules, LCCs, drive fan pack, power supplies).

If the icon for any CRU is grey, the CRU is operating normally. If the icon for any CRU is white, the CRU was not in the chassis when DAE-MON started managing the DAE.

For more information about a CRU's state, click its icon and look at the status window that opens.

If the Array Status button contains the word Fault - One or more of the managed DAEs is either inaccessible or faulted. Look in the Daemon window for inaccessible or amber array icons, and follow the procedure below for icon type.

For an inaccessible array icon

Follow the steps below for the DAE represented by the inaccessible array icon.

NOTE: Refer to the DAE installation and service guide for the proper procedures for setting a DAE's EA switch or replacing or installing its CRUs. (The installation and service guide for a rackmount DAE is the Dell™ PowerVault™630F and 250F Rackmount Storage Systems Installation and Service Guide (P/N 4867C); and for a deskside DAE, it is the Dell™ PowerVault™ 251F Deskside Storage System Installation and Service Guide (P/N 2867C).)

Make sure the DAE's enclosure address is unique.

1. Reinstall any disk module that was removed from slots 0-3.
2. Replace any disk module in slots 0-3 with its Check light on.
3. Reinstall any removed LCC.
4. Replace of any LCC with its Check light lit.
5. If the cabling for either LCC is removed or faulty, reinstall or replace it.

For an amber array icon

Double-click the amber array icon.

The Equipment view opens for the DAE represented by the array icon.

1. In the Equipment window, look for amber CRU icons.

The CRU represented by an amber CRU icon is in one of the states listed below.

Table 3-13. Meaning of an amber CRU icon

1. Look at the amber Check light on any CRU whose icon is amber.

If this Check light is on, the CRU has failed and will need replacing as soon as possible, as described in the DAE installation and service guide. (The installation and service guide for a rackmount DAE is the Dell™ PowerVault™ 630F and 250F Rackmount Storage Systems Installation and Service Guide (P/N 4867C); and for a deskside DAE, it is the Dell™ PowerVault™ 251F Deskside Storage System Installation and Service Guide (P/N 2867C).)

NOTE: If the drive fan pack is removed for more than two minutes, the FC-AL interconnect system continues to operate, but the disk modules power down. The disk modules power up when the drive pack is reinstalled.

If a CRU fails in a DAE that is not highly available (that is, one that has just one LCC and one power supply), the DAE may not be operable or accessible while the CRU is replaced. If a CRU fails in a DAE that is highly available (that is, one that has two LCCs and two power supplies), the DAE's high availability is compromised until the faulty CRU is replaced.

What next?

Continue to the next section to exit DAE-MON.

Exiting DAE-MON

From either the Daemon or Equipment window, follow this menu path:

File � Exit

Any open DAE-MON windows close, and you exit DAE-MON.
