Diagnostics and Troubleshooting Reference Manual – Virtual SAN Launching VSAN Observer without internet access In order to configure VSAN Observer to work without internet connectivity (offline mode) a number of files need to be modified. The html files which need to be modified are located in the following direcory on the vCenter Server Appliance: The files are: /opt/vmware/rvc/lib/rvc/observer/ graphs.html history.erb.html login.erb.html stats.erb.html This procedure will now show you how to modify the files so that VSAN Observer can work without accessing the Internet. JavaScript and CSS files downloads In each of the html files (graphs.html, stats.erb.html, history.erb.html and login.erb.html) there are external references to JavaScript and CSS libraries. The CSS libraries have reference to external fonts. The objective is to download these files locally so that RVC doesn’t need to pull them down from the internet. Here is an example of the files which have internet references and will need to be downloaded locally: # head -15 graphs.html.orig There are a number of javascript (js) files and CSS files to be downlaoded. In this example, a folder called “externallibs” is created under the directory /opt/vmware/rvc/lib/rvc/observer/ and is used to place the respective JavaScript, CSS, and font files in each subdirectory.

Diagnostics and Troubleshooting Reference Manual – Virtual SAN A very useful command for downloading the files is wget, which is shipped with the vCenter Server Appliance. Another option is to use cURL. Obviously this will mean that your appliance will need Internet connectivity in order to download the files. Simply change directory to the folder where you wish the file to be downloaded, and run as follows: # wget https://code.jquery.com/ui/1.9.1/jquery-ui.min.js --2014-12-05 10:31:57-- https://code.jquery.com/ui/1.9.1/jquery-ui.min.js Resolving code.jquery.com... 94.31.29.230, 94.31.29.53 Connecting to code.jquery.com|94.31.29.230|:443... connected. HTTP request sent, awaiting response... 200 OK Length: 237108 (232K) [application/x-javascript] Saving to: `jquery-ui.min.js' 100%[================================================>] 237,108 481K/s in 0.5s 2014-12-05 10:31:58 (481 KB/s) - `jquery-ui.min.js' saved [237108/237108] # If it is not possible to provide, even temporarily, Internet access to the vCenter Server Appliance, then an alternative method will have to be used to download the files and later transfer them to the vCenter Server appliance that is running RVC. Determining which fonts to download is a little bit more difficult. The fonts are found in the font CSS file. Look for the “url” keyword in the file to see which ones are need. The full list is in the structure below. VSAN Observer folder structure Here is the list of files, and where they need to be placed in the new folder structure: Top folder - externallibs Sub folders – js, css, font Sub folder - js angular.min.js bootstrap.min.js d3.v3.min.js jquery-1.9.1.min.js jquery-ui.min.js jquery.js Sub folder – css bootstrap-combined.no-icons.min.css font-awesome.css Sub folder – font FontAwesome.otf fontawesome-webfont.eot V M W A R E S T O R A G E B U D O C U M E N T A T I O N / 1 9 9
