Configuring a Network
Network configuration in the UCS-SCU allows you to configure the network by providing IP details, proxy details, cisco credential details and so on. It is a one-time process, and if you do not configure your network, you will be prompted to configure it during the following procedures:
When you are downloading drivers from the network share or cisco.com during the operating system installation. (See the Installation Drivers section).
To configure a network, follow these steps:
Click the Network Configuration button on the toolbar.
The Network Configuration dialog box appears.
In the Network Configuration dialog box, do the following:
Select IP Address from DHCP server or Static IP Address. If you select Static IP Address, do the following:
In the IP Address field, enter the IPv4 address.
In the Subnet Mask field, enter the subnet IPv4 address.
In the Gateway field, enter the gateway IPv4 address.
(Optional) In the DNS field, enter the DNS IPv4 address.
Go to Step b. if you want to download software and drivers from cisco.com.
Select Direct Connection to internet or Manual Proxy. If you select Manual Proxy, do the following:
In the HTTP Proxy Server URL field, enter the URL of the proxy server. The maximum limit is 45 characters.
In the Port field, enter the port number. The maximum limit is 5 characters. By default, it is 8080.
In the Proxy Server UserName field, enter the user name of the proxy server. The maximum limit is 45 characters.
In the Proxy Server Password field, enter the password of the proxy server. The maximum limit is 45 characters.
Click Configure to save the settings.
Performing Server Health Check
The Probe Server functionality allows to perform a health check of the server subsystems. When you click the Probe Server icon, the server health check is initiated.
To view the health check results, click the Server Health tab in the navigation pane.
You can use the Save Logs functionality to save your log files. Before using Save Logs, you must insert a USB flash drive or vMedia for storing the log files.
Using Server Snapshot
You can use the Server Snapshot feature in the 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. Before you initiate a server snapshot, be sure 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 can take approximately 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, we recommend that you store these log files in a location and archive it. When you have multiple log files, you can use a comparison tool from the Internet to view differences in the server inventory.
To take a server snapshot, follow these steps:
Connect a USB flash drive to the server or through vMedia.
Without this flash drive, you cannot save the server snapshot log file. Be sure that there is adequate space on the flash drive to save the log file.
Click the Server Snapshot icon in the UCS SCU interface.
A dialog box is displayed that prompts you to insert the USB flash drive.
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.
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.
During the server snapshot process, if the KVM connection is terminated, it does not terminate the server snapshot process. When you log in again to 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.
After the snapshot process is complete, a dialog box message appears to indicate that the server snapshot process is complete
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.
Open this log file with any editor.
To compare inventory information of the same server over a period of time, we recommend that you archive these log files so that they are always available for comparison
While running quick tests on the server, the server snapshot feature can determine only 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.
To know more about Diagnostic Tools, go to the Chapter 7, Understanding Diagnostic Tools.
The log file of the server snapshot process includes the following information:
PCI Adapter Summary
Power Supply Summary
Server diagnostics Quick Test Results
Server Probe Data

Synchronizing the Hypervisor Partition
On servers that support the Cisco FlexFlash SD card, UCS-SCU provides an option to synchronize the Hypervisor virtual disk, on the SD card, configured as a RAID-1 disk. This feature is available only when both slots of the Cisco FlexFlash SD card are populated. UCS-SCU detects the presence and absence of SD cards on the server.
When one member slot of the SD card is corrupt, use this option to synchronize the Hypervisor data across 2 members of the RAID-1 virtual disk. You can initiate this synchronization only if 2 cards are detected and RAID-1 is determined as unhealthy (one member is corrupt).
Click the Hypervisor Sync icon on the toolbar of UCS-SCU interface.
A dialog box prompts you to confirm that you want to synchronize the hypervisor RAID.
When the synchronization is complete, a dialog box indicating the completion of the synchronization is displayed.
After you click OK, the Hypervisor Sync icon on the toolbar is greyed out.
Restarting the Server
To restart the server, follow these steps:
Click the Reboot icon on the toolbar.
The Reboot dialog box appears.
Click Yes to restart.
The server restarts, and the UCS-SCU GUI reappears.
