You can use the Server Snapshot feature in UCS SCU user interface to take a point-in-time inventory of a server. This feature allows you to compare inventories or components of a server over certain periods of time. Prior to initiating a server snapshot, ensure that you connect a USB flash drive into the server. Without a flash drive available, the log file created by the server snapshot is not saved.
When you initiate a server snapshot, UCS SCU retrieves information on the server components, and also runs a series of quick tests to determine the state of the server. Taking a server snapshot could take around 20 minutes. After the server snapshot process is complete, the log file is saved on to the USB flash drive that you specified. You can open this log file in any editor. For example, WordPad. To help compare server inventories across time periods, it is recommended that you store these log files in a location and archive it. When you have multiple logs files, you can use a comparison tool from the Internet to view differences in the server inventory.
To take a server snapshot, perform these steps:
Step 1 Connect a USB flash drive to the server or through vMedia.
Without this flash drive, you cannot save the server snapshot log file. Also ensure that there is adequate space on the flash drive to save the log file.
Step 2 Click the Server Snapshot icon in the UCS SCU interface.
A dialog box prompting you to insert the USB flash drive is displayed.
Step 3 Click Yes to continue.
A dialog box prompts you to select the USB flash drive in which you would like to save the log file.
Step 4 Choose the USB flash drive from the drop-down menu and click Save.
The Server Snapshot process is initiated. This process could last up to 20 to 30 minutes. A dialog box indicating the progress of the server snapshot process appears. During this process, you cannot perform any other tasks on the server. At any moment during the process, you can cancel the server snapshot process by clicking Cancel in the dialog box.
Note During the server snapshot process, if the KVM connection is terminated, it does not terminate the server snapshot process. When you login again to the KVM console, you will notice that the server snapshot process is still running or has completed. However, if the USB flash drive is connected through vMedia and the KVM connection is terminated, then the server snapshot process is halted as the connection to the USB flash drive is lost.
Step 5 After the snapshot process is complete, a dialog message appears to indicate that the server snapshot process is complete. Click OK.
The log file is saved on the USB flash drive. The log file is a text file and is saved with the server name and includes the date when the server snapshot was taken. For example: Server_C260-BASE-2646_FCH1234345_06_08_2011 is the log file name of a server snapshot taken for UCS C-260 server on August 6th, 2001.
Step 6 Open this log file with any editor. For example, WordPad.
Tip To compare inventory information of the same server over a period of time, it is recommended that you archive these log files so that they are always available for comparison.
The log file of the server snapshot process includes the following information:
•Chassis Summary
•BaseBoard Summary
•CIMC Summary
•Processor Summary
•Memory Summary
•Storage Summary
•PCI Adapter Summary
•Power Supply Summary
•Server diagnostics Quick Test Results
•Server Probe Data
Note The server snapshot feature, while running quick tests on the server, can only determine if a server component passed or failed a test. It cannot determine the reasons for a component not passing the quick test. While viewing the log file of the server snapshot process, if you notice that a server component did not pass the quick test, then check the quick test logs available under the Diagnostics Tools.
You can configure your server's BIOS boot order settings and perform RAID configuration using the Server Configuration function. To enter this function area, from the left navigation pane, click Server Configuration.
