The BMC allows for remote management of the G8 server from a Web based UI. The advantages over using SSH are that you get access to things like the BIOS, the Console and can even start the server if it has done a power down. | The BMC allows for remote management of the G8 server from a Web based UI.

+ | ==== BMC Configuration ==== | ||
+ | \\ | ||
+ | \\ | ||
+ | Turn on the server from cold, and wait for the Boot Options page: | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | From this page select <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | After a short time, you will see the initial BIOS page. | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | From this page, move down to and select <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | When the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | From the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | The BMC LAN Configuration page shows two sets of IP Settings. Baseboard LAN Configuration and <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | It is the Dedicated Management LAN Configuration we need to set. If no BMC address has ever been configured, then it will be 0.0.0.0 for everything, you need to configure this for your network, in this example we have used the following: | ||
+ | < | ||
+ | IP Source - < | ||
+ | IP Address - 10.43.30.21 | ||
+ | Subnet Mask - 255.255.255.0 | ||
+ | Gateway IP - 10.43.30.254 | ||
+ | </ | ||
+ | \\ | ||
+ | Once the IP settings have been configured, you need to scroll to the top of the page, and select <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | Once the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | There are some pre-defined users - Anonymous, User2, User3 etc. I would avoid using Anonymous and configure <color # | ||
+ | < | ||
+ | User2 | ||
+ | Privilege < | ||
+ | User Status < | ||
+ | Username - root | ||
+ | User Password - envivio | ||
+ | </ | ||
+ | \\ | ||
+ | To finish the setup, press F10 (F10=Save Changes and Exit) | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | Press <color # | ||
+ | \\ | ||

+ | ==== BMC Useage ==== | ||
+ | \\ | ||
+ | \\ | ||
+ | Using a <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | You will see a login page (you will have to go through a browser challenge to get here) | ||
+ | \\ | ||
+ | \\ | ||
+ | Enter the username/ | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | You can now navigate around the BMC options using just a web browser. For me one of the most useful features is on the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | Click the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | Just under the title KVM/Console Redirection, | ||
+ | \\ | ||
+ | \\ | ||
+ | Depending on your browser, you might get a window asking for login details, use the BMC login, not the OS login. If you don't get this window, you just have to login from the command prompt. | ||
+ | \\ | ||
+ | \\ | ||
+ | {{ : | ||
+ | \\ | ||
+ | \\ | ||
+ | You can now use the console in the same way you use SSH, so this is really useful if the only available port to the G8 server is port 80 (ssh requires port 22 for example) | ||
+ | \\ | ||
+ | \\ | ||
+ | |||
+ | ---- | ||
+ | \\ | ||
+ | ==== Diagnostic Example ==== | ||
+ | \\ | ||
+ | \\ | ||
+ | When using the Web Console, there are many things you can do, one of these is to look at the server logs. Click on the second tab <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | Now click the <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | {{: | ||
+ | \\ | ||
+ | \\ | ||
+ | I had a server that would not install any OS, and kept rebooting. The install errors made little sense, so the Even Log was checked by a colleague, and here we can see that is is full of <color # | ||
+ | \\ | ||
+ | \\ | ||
+ | So if you have a server that is being troublesome, | ||
