Lab 1b BC-E management using the MM (Management Module) Web Interface

Introduction In this lab, you will use the features and functions of the BladeCenter management module Web interface. Note: For Virtual Classroom students, all features of this lab are available, except the ability to view the LEDs directly on the BladeCenter. This is done using the LED portrayals on your display. Because most service representatives perform support remotely without the chance for visual confirmation on the actual equipment, this is not a cause for concern.


z Manage the BC (BladeCenter) resources via the BladeCenter MM ( Management Module)

z Connect to the MM Web interface and use the management module monitors to view system status, the event log, LED status and the Vital Product Data.

z Use management module blade tasks to control a blade server. z Use the management module tasks to upgrade firmware z Use the management module switch tasks to configure the switch and perform routine

switch management including starting a browser session to the switch Web server

BladeCenter - E2E Support Training for RSC, Part II Lab 1B


Directions Start a Remote Console session into the Instructor designated, private LAN workstation. There are a number of the Workstations and servers in the Remote Lab. A quick review of a sample Net View command below shows ten (10) BC Workstations, six (6) Classroom Workstations, two (2) Domain Controllers, and two (2) Director Servers on this private network. NOTE: In order to see what is currently available, you may run the Net View command from a remote workstation after you remote connect into it (Step 3 below.)

Sample Output of NETVIEW Command



____1. In order to gain access to the Lab Workstations, your instructor will provide the hostname and lab IP addresses for the equipment you will use for your lab exercises.

Note: ONLY use the Workstation and Bladecenter that you are assigned, as other classes and students may be using some of the other equipment. Also these USER IDs / Passwords are to be used ONLY during your scheduled class. Since this a World Wide training center, ALL students must abide by these same rules in order to prevent training issues and conflicts during remote classes.

____2. Open a Remote Console session into your assigned workstation. (This is normally found in the Start/Programs/Accessories/Communication folder. It can also be run from a command line. Start, run, C:\WINDOWS\system32\mstsc.exe If it is not found on your machine, then perhaps you will need to install this windows component. (Start, settings, control panel, add/remove programs then select add windows components.)

____3. Once started, a window should open like the one below, where you enter the remote Workstation name or IP address.

____4. Enter your userid and password when prompted.



Congratulations! If all went well, you should now be controlling a computer with connection to the remote training Lab. This is the first step to working with one of the remote lab BladeCenters.



Directions Become familiar with the management module menu system Note: The default configuration of the external port of the management module is with

DHCP enabled. If the attempt to obtain an IP address via DHCP is NOT successful, the external port has the default address of 192.168.70.125 with the default subnet address 255.255.255.0 as its IP address.

On the remote management workstation, start your web browser. Perform the following steps:

____1. Enter the IP address of the management module Web server in the address bar and press . The logon screen will display.

____2. Enter USERID in The User Name field, enter PASSW0RD in the Password field and select . The default user ID and password are USERID and PASSW0RD (0 is a zero). These are case sensitive. Once you enter your user ID and password, you will be presented with a welcome window that displays where you are connected and where you can set the duration that your connection can be idle before being automatically disconnected.

____3. If the screen informs you that there is already a logon with the same ID, then double check your IP Address. It could be that you or someone else is on the wrong MM, or it could be that the last person to log on chose to never disconnect with inactivity, and then failed to log out. In either case, when you log on using the same ID, you will generally disconnect the other session using your same ID; however, if the IDs are different, it is possible for multiple people to be logged into the same MM at the same time.)



Active Session Notification

____4. Press . The BladeCenter Management and Configuration window opens. From the Management and Configuration program main menu, you can select settings that you want to view or change.



System Status View

____5. Looking down the left side, the choices are : System Status, Blade Tasks, I/O Module Tasks, MM Control, and LOG OFF (Note: If your BC- E has the newer AMM (Advanced Management Module ) there will also be a section called Service Tools .)

____6. In the System Status Summary section, Select the link. This will advance the screen down to the Blade Servers section. This section displays a table, which shows the status of all the blades in the chassis. The table has 14 rows for the 14 blade slots. The empty slots are marked as such.

____7. Select the green status indicator light < > for any installed HS20 blade. (Note: Observe how the curser changes from an arrow to a closed hand signifying that this is a link to a new page which contains additional information. Also Observe the Blade Status Summary and Environmentals



for the Blade Server. The blade needs to be Powered ON for the MM to measure the Blade Server Environmentals.)

____8. Return to the System Status screen by selecting System Status in the Monitors section on the left side. Select the link in the System Status summary section on the right side. This will advance to the I/O Modules section. This section displays a table, which shows the status of all the switch modules in the chassis. The table shows four (4) rows for the four (4) switch module bays.

____9. Scroll down to the section. This section displays a table, which shows the status of the management modules in the chassis. The table has two (2) rows for the two (2) management module bays.

____10. Scroll down to the Section. This section displays a table, which shows the status of the fans in the chassis. The table shows two (2) rows for the two (2) fan bays.

____11. Scroll down to the section. This section displays the ambient temperature reading for the front panel along with the warning and warning reset thresholds. If the temperature reaches the warning threshold, a warning event is generated. (Note: If the temperature goes above the warning threshold and then drops below the warning reset threshold, any active temperature events are then cleared.)



Directions View the event log On the left window of the display, make sure the Monitors menu is expanded. Select . The Event Log screen displays:

Question 1: What are the levels of severities that are available in the Event log?

Answer:



Note. The 'Sev', 'Source', and 'Date/Time' column headings are selectable. They can be used to sort the log entries in ascending or descending order of severity, logging source, and timestamp, respectively. Selecting on these column headings multiple times has the effect of toggling the sorting order. (top to bottom, or bottom to top)

The log entries can also be filtered using the log filter controls at the top of the page.

Under severity, Select , then Select . This will display the warning

events only.

To disable the current filter settings and view all log entries, select the button.

To save the entire event log entries in a text file on your computer, select the button.

To delete all the event log entries select the button. This operation cannot be undone. (It is important to save the file before clearing the log, else you and/or tech support will not be certain of the errors that may have occurred on this BC)

off). Notice the HS20 power indicators.

Enable or disable the local power control. When local power control is enabled, a local user can turn the blade on or off by pressing the Power-on button on the blade. (Remote users will have to take my word that the Power Button has been disabled/enabled in the next steps.)

A) Try to turn the Blade server on locally after you disabled the local power control

B) Enable the local power control, and then try to power the blade server locally

Enable or disable Wake on LAN. Notice the status on the table.

Restart the blade or the Blade System Management processor (now called a BMC) in the blade. (NOTE: This feature may NOT be available from all MM/AMMs depending on your code levels.)

Directions Set date and time It is very important to set the correct time on the management module in case of any problems. The event log will log events using the date/time set within the management module. (Note: This is especially important when troubleshooting, and you are



comparing events in the NOS logs, with information found from the BC Hardware Logs. NTP (Network Time Protocol) can also be used to synchronize the clock.) Make sure the MM Control menu is expanded, and then select .

Verify date and time. If they need to be changed, select . Enter the correct time and select .

____7. To complete the update process, select . A progress indicator will be displayed as the firmware update progresses.

____8. Remain on this page until the process is complete, at which point a status page will be displayed to indicate whether the update was successful. Additional instructions will be displayed on this page if necessary.

____9. Repeat the above steps for each packet on the diskette.

____10. After receiving a confirmation that the update process is complete, go to the Restart Management Module page and select



____11. Select to confirm that you want to restart the Management Module.

Note: The Management Module will restart. This will not affect the Blade server power on status.

Question 7: What is the build ID revision for each of the firmware type Answer:

Directions Manage a I/O Module Note. In order to have access to a switch module internal network link from the

management module external network link, the switch module and the internal and external network interfaces of the management module must be on the same subnet. Depending on which switches are physically located in your BladeCenter, will determine what Features are available from their Web Interface. For example, from the D-Link switch you can backup and restore the Switch Configuration file, from the Connectivity Module the address may be using PAT (Port Address Translation) For this class we will just do some very basic snooping on the Cisco Layer 2+ switch, and similar things on one of the Nortel Switches. (Note: Advanced Switch Configuration is taught in the XWI10 BC Class.)

____1. Make sure the I/O Tasks menu is expanded then select the

link. The I/O Configuration screen will display.

Directions Fuel Gauge BladeCenter Fuel Gauge - Overview: The Fuel Gauge presents overall power information based on projected power consumption for the system. Important Concepts

There are two power domains in the chassis. See Power Domain Details for the list of components powered in each domain.

There must be at least one functioning power supply in power module bay 1 or 2. Power modules must be the same rating in a power domain. Power Management Policy Settings available in Fuel Gauge allow the

administrator to decide how the system reacts per power domain upon the loss of a power module (AC source failure or power module failure).

The combination of the system's configuration, Power Management Policy Settings, and available power may cause blades to throttle or not power on.

When a 1200W or 1400W power module is installed in the domain the power management policy will not be applicable. In addition the power consumption in this domain will not be monitored.

Power Management Settings The settings are applied to each power domain independently. It is recommended that management module firmware, blade bios, and blade systems management firmware be maintained at current levels to insure accurate reporting of power information. There are three settings available:

Redundant without performance impact: Blades will power on only if they can operate without throttling if power redundancy is lost. The number of Blades allowed to power on is determined by the power available from one power module. If power module redundancy is lost, all the blades that are powered on will continue to operate at their un-throttled performance levels.

Redundant with potential performance impact: Blades will be allowed to power on as long as the power consumed is less than or equal to the "Total Power" under this policy. If power module redundancy is lost, processors on blades capable of throttling, will throttle in order to reduce the power consumed to less than or equal to the power modules rated capacity. Blades will power up in a throttled state in some configurations. Upon restoration of power redundancy, the blade processors will return to their un-throttled performance levels.



Non-redundant: Blades will be allowed to power on as long as the power consumed is less than or equal to the "Total Power" under this policy. If power module redundancy is lost, processors on blades capable of throttling, will throttle in order to reduce the power consumed to less than or equal to the power module's rated capacity. Processors return to their normal power states when power redundancy is restored. (Note: There may be certain configurations which may result in loss of power in the domain.)

The system utilizes power management technologies built into certain processors to throttle the blades. ____1. From the Monitors menu, select Fuel Gauge. Review the current settings

and scroll down to how much power each module consumes.

____2. Select .

____3. Scroll up and select .

____4. Read about the different Power Management Policy Settings and become familiar with the different options.

____5. Close the help window.

____6. Change the Power Management Policy Settings to for both domains.

____7. Try to power ON all blades within the chassis. This is the most restrictive setting.

BladeCenter management summary When a BladeCenter ships, it is configured with a number of default values for the management module and switch modules. This allows local access to configure the various shared components of the BladeCenter.



Both the management module and the switch module provide Web servers for local access through a browser. The management module external interface is enabled at all times but the external switch ports are disabled by default. There is an internal Ethernet connection between the management module and the switch module. In a customer environment, it is likely that the IP addresses of the management module and switches will be changed to meet customer needs. If the defaults have been changed, the customer should have a document with the new values. If you do not know the IP address of the external Ethernet port of the management module, it cannot accessed with a web browser. As the modules have browser interfaces, they are reasonably intuitive to use. The basic features of the management module are similar to the Remote Supervisor Adapter. The more advanced features are specific to the BladeCenter. You have now completed all the steps in this lab. You will find the answers to the questions in the appendix to this lab guide
