Power Tool Tip Troubleshooting
If there is an issue with your power configuration, the system warns you by highlighting the problems in the tool tip. In this example, there is an issue with the potential failover load. There might be a problem even if there seems to still be power available. Follow the below instructions to troubleshoot.
To troubleshoot, enable the advanced power tool tip and see details about the phases and feeds. Select Tools>Preferences to access the Preferences dialog box.
Select Advanced Power.
Now, hover over the rack again and inspect the tool tip.
The tool tip reveals why the configuration does not provide enough power in case of a failover. This is a 3 phase configuration and phase L1 on the A-Feed UPS would be overloaded in case of a failover. This causes an issue regardless of the available power on the other phases.
If the estimated load would also be highlighted in red, there would be a similar issue with this value and the solution would be the same: to reconfigure the phase configuration.

What does the Power Tool Tip Tell Me?
Troubleshooting why Capture Index Values do not
Display
The cooling simulation updates based on the equipment placement. If your configuration is invalid, the tool tip will inform you of the problem. If the cooling calculations do not run, verify your configuration is not invalid due to one of the following:
The distance between the racks is insufficient (at least 2 feet). Hot air blows from one rack into the front of another rack. To make the cooling configuration valid, use the room layout icons and drag the row border to make the aisle wider.
1. 2.
There is a piece of equipment placed in the aisle between the rows. To make the cooling configuration valid, move the equipment out of the aisle.

Generating Reports on Linux
On some Linux distributions, generating reports might fail due to missing libraries or default settings.
If the client crashes during report generation or if this error message (see image) appears, this will fix the issue:
Open the StruxureWare Data Center Operation.ini file. The default location of the .ini file is C:\Program Files\StruxureWare Data Center Operation 7.4.5\application.
Write
Dorg.eclipse.swt.browser.DefaultType=mozilla
Dorg.eclipse.swt.browser.XULRunnerPath="/path/to/<xulrunner>"
If you do not have XULRunner installed, you can download it here. Version 1.9.x should work in most cases. Otherwise, check which version is supported for your version of Firefox.

Symptom Explanation Solution
Error message:
Could not connect to server at specified address. Ensure the specified server is running.
One or more of the following conditions might exist:
The specified server is not responding because it is not running. The specified server refused the connection request because it is not a Data Center Operation server.
Contact your Data Center Operation server administrator.
: Replace with the real path to the XULRunner on your machine.
Error Condition: The mobile device application cannot connect to or synchronize with the server.
If the mobile device is on a wireless network, that network may be experiencing problems, or the server may be off-line.
Ensure that the wireless network is enabled. Use the ping command from a desktop computer or through the network connection software on the mobile device to determine whether the server is operating correctly.
If the mobile device is in its cradle, one or more physical connections may be loose.
Ensure that the cable from the cradle is securely attached and that the mobile device is firmly in the cradle. Microsoft® ActiveSync® or Windows
Mobile Device Center (WMDC) for Windows Vista might be unavailable or not running.
Ensure that ActiveSync or WMDC is available and running on the computer.

Troubleshooting operational problems
How to correct problems that may occur when performing StruxureWare Data Center Operation: Mobile functions.
Symptom Explanation Solution
You experience frequent error messages, or your mobile device interface or the Strux
ap ureWare Data Center Operation: Mobile plication is frequently unresponsive.
You are working in server mode, and the network connection is unstable. StruxureW
can run are Data Center Operation: Mobile with a variety of other applications, but if other applications are too numerous or too large, insufficient memory can cause errors.
Check your wireless network connection, or connect through the cradle and switch to local mode to work in a mode that does not require network connection. (Remember to connect and synchronize regularly.) See your mobile device documentation for instructions on checking memory usage. If memory is insufficient, uninstall
unnecessary applications.

Troubleshooting virtualization issues
1. 2. 3. 4.
Type of events that you might see: Discovery
Monitoring Recovery
Why don't I see all my virtual machine hosts in the list in Microsoft System
Center Operations Manager?
The list of virtual machine hosts is not a complete list of all hosts monitored in Microsoft System Center Operations Manager. It is a list of those that have been associated with modeled objects in StruxureWare Data Center Operation.
StruxureWare Data Center Operation: PRO Pack retrieves data from StruxureWare Data Center Operation at a specified polling interval. If you do not see all the virtual machine hosts that you expect to see, wait for the specified period of time and the view will be updated with the latest data.
Discovery: 4 hours Monitoring: 30 seconds
I get many reports of impacted virtual machine hosts. What could be the
cause of this?
Ensure the configuration represents the real-world physical environment as accurately as possible. For example, the system will reflect the real-world more accurately if you configure power connections all the way down to the server level than if you stop at the rack PDU level. If the system is missing the server connection data, it will use the information available. It will report more impacts because it does not know which servers are connected to which rack PDUs.
If a rack PDU in a rack is critically impacted by an alarm, the system will assume that all servers are connected to that rack PDU are impacted by the alarm.
If there are two rack PDUs in a rack, the system will assume that all servers with redundancy are connected to these two rack PDUs are impacted by the alarm.
Virtual Machine Manager does not migrate virtual machines to a host. What
could be the cause of this?
If a host outside a cluster was previously impacted, StruxureWare Data Center Operation: PRO Pack changed the status of this host from available for placement to unavailable. Once you have resolved the issue and the host is healthy, you must make it available again: In Virtual Machine Manager, right-click the host in Virtual Machines > Host Groups, select Properties > Status, and select This host is available
.

Slow server/client connection
If the connection between the StruxureWare Data Center Operation server and client is slow, add an exception in the connection options for the StruxureWare Data Center Operation IP address.
The StruxureWare Data Center Operation client uses the proxy settings from the operating system. If you are running on Windows, you can configure the settings through the Internet Explorer connection options.
In Internet Explorer, select Tools>Internet Options. Select the Connections tab.
Click LAN settings.
In Proxy server, select Use a proxy server for your LAN. Click Advanced.
In Exceptions, add your exceptions separated by semi-colon.
Scaling client memory allocation for large solutions
Working with large solutions/rooms with many racks/assets, the client might run out of memory (java heap space error). To increase the amount of assets that can be loaded at the same time in the client, you can modify the configuration ini file.
Browse to C:\Program Files (x86)\<Operation version, e.g. StruxureWare Data Center Operation 7.3>\application
Open the StruxureWare Data Center Operation.ini file in a text editor, such as Notepad++. Edit the line
corresponding to an average of 1200 racks to -Xmx768M
which should double the memory (2400 racks). -Xmx1500M
There is an upper limit to how much memory could be allocated with the -Xmx parameter and in some cases, you will not be able to launch the client. In that case, decrease the value again.

When you use the StruxureWare DC Operation>Download Log Files option, the system includes the data from the Debug p age in the log. But first, you must open the Debug page.
Log on to Webmin using the user credentials created during the installation. In the left menu, select StruxureWare DC Operation>Debug.
You may also be asked to start the JVM logger (option at the top of the Debug page) while you are experiencing issues if the server is running out of memory.
The logger slows down the system so make sure to stop it again after troubleshooting. The data is stored on the server in /var/log/jvmstat.log.
