vSphere Client Login UI customizations do not persist in VCSA 6.5 Update 1

08.03.2017 by William Lam // 3 Comments

The much anticipated release of vSphere 6.5 Update 1 just GA'ed late last week and like many in the community, I also went ahead and upgraded my home lab to this latest release. vSphere 6.5 Update 1 contains a ton of fixes as well as several new capabilities which you can read all about in the release notes here and here.

One neat little trick I take advantage of in my lab environments when deploying the vCenter Server Appliance (VCSA) is actually pre-filling out the credentials for the vSphere Client UI (not recommended for production environments of course) which I had blogged about here a few years back. Sine I have many different environments for different scenarios, I find myself being lazy and having to type in the credentials to each one of these environments. Instead, I can pre-fill either the username and/or password (which I will stress again, not recommended for production) within the vSphere Client Login UI page which is simply just using HTML.

After making the necessary changes to my VCSA 6.5u1 system, I needed to reboot my ESXi host and when everything came back up, I was surprised to find my changes to the vSphere Client Login UI had disappeared. It took me awhile to figure out why the changes were not persisting across reboots. There seems to be a change in behavior compared to prior releases of the VCSA (6.0 & 6.5) on when this capability was actually possible.

Erasing existing disk partitions now available in the vSphere Web Client (vSphere 6.0 Update 1)

09.29.2015 by William Lam // 9 Comments

One of the primary challenges when trying re-purpose existing storage devices is ensuring that all data and existing partitions have been completely removed. Often times, customers end up resorting to third-party tools like GParted which requires you to boot your server into the LiveCD before you can remove the existing partitions. This is less than ideal, especially if you need to perform this operation across multiple systems.

For customers who wish to re-purpose their existing storage devices for other use, including VSAN, there is now a new UI option in the vSphere Web Client introduced in vSphere 6.0 Update 1 to help assist with this procedure. I had not seen anyone talk about this feature yet and figure I would share some details as this is something I have heard customers ask for in the past. You can find this new option (icon with disk and eraser) by clicking onto a specific ESXi host and then selecting the Manage->Storage Adapters and then highlighting the specific storage device you wish to erase as seen in the screenshot below.

Once the erase partition icon or action is selected, you will then be presented with a summary of the existing partitions on the disk and then prompted to confirm that you wish to delete ALL partitions on the disk.

After the operation has successfully completed, you can now re-purpose the storage device for other use like VSAN!

For those of you who are interested from an Automation standpoint, this UI operation actually makes use of an existing vSphere API that has been for quite some time called updateDiskPartitions() under the StorageSystem manager of an ESXi host. To erase all partitions, you simply pass in an empty spec to the API method.

In addition, I also want to quickly mention that you will also have the ability to edit and erase existing disk partitions using the ESXi Embedded Host Client Fling which will be available in a future update. Below is a quick screenshot on what that would look like.

Getting Rid of the Inventory Tree in the New vSphere Web Client

11.26.2012 by William Lam // 2 Comments

I don't know about you, but I really like using the new inventory list compared to the old inventory tree when I need to find something in new vSphere Web Client. The inventory list does not rely on the static and limited hierarchical tree view to display your vSphere objects. Instead, it groups common vSphere objects together (works across multiple vCenter Servers) along with links to other related objects. This allows you to quickly navigate to a particular vSphere object and with just a click away to other related objects for further inspection. Finally, you will no longer have to worry about the "white screen of death" which was a common problem when trying to display huge inventories and sometimes even smaller ones while using the tree view.

To be honest, I was not a fan of the inventory list at first, but after spending some time with it, I quickly realized the benefits of moving away from the old hierarchical tree view. I actually like the new inventory list so much, that I personally wanted like to get rid of the inventory tree view as it is an extra mouse movement to get to the inventory list. I sometimes even accidentally click on the inventory tree when browsing too quickly through the vSphere Web Client.

I thought it might be a long shot to see if it was possible to remove the inventory tree since I assumed it might be part of the compiled code. Surprisingly, I found out from one of the developers, there was actually a pretty simple way (aka "hack") of removing the inventory tree.

Disclaimer: This is probably not officially supported by VMware, please use at your own risk.

In the example below, I am using the VCSA (vCenter Server Appliance) which has the vSphere Web Client installed by default but this should also work for a Windows vCenter Server that has the vSphere Web Client Server installed.

Step 1 - We need to make a backup of the following file /usr/lib/vmware-vsphere-client/plugin-packages/vsphere-client/plugins/inventory-viewer-war-5.1.0.war which contains the file that we need to edit. The command below will just make a backup copy called inventory-viewer-war-5.1.0.war.BAK

cp /usr/lib/vmware-vsphere-client/plugin-packages/vsphere-client/plugins/inventory-viewer-war-5.1.0.war /usr/lib/vmware-vsphere-client/plugin-packages/vsphere-client/plugins/inventory-viewer-war-5.1.0.war.BAK

Step 2 - Next, we will go ahead and extract the contents of the WAR file which is basically a zip archive in our home directory so that we can edit a file. Run the following command which will extract the contents into a directory called TEMP under /root.

unzip /usr/lib/vmware-vsphere-client/plugin-packages/vsphere-client/plugins/inventory-viewer-war-5.1.0.war -d ~/TEMP

Step 3 - Change into the ~/TEMP directory and you should see a file called plugin.xml which we will be editing. Use an editor such as vi and locate the following section and comment it all out using the notation as shown below
Step 4 - Once you have finished editing the plugin.xml file, go ahead and save the file. Now we will need to re-create the inventory-viewer-war-5.1.0.war file and to do so, inside the TEMP directory, run the following command:

zip -r inventory-viewer-war-5.1.0.war *

Step 5 - We now need to copy the modified inventory-viewer-war-5.1.0.war back into the vSphere Client Plugins directory. Run the following command to copy the WAR file into plugins directory:

cp inventory-viewer-war-5.1.0.war /usr/lib/vmware-vsphere-client/plugin-packages/vsphere-client/plugins/inventory-viewer-war-5.1.0.war

Step 6- Finally, for the changes to go into effect, we just need to restart the vSphere Web Client service by running the following command:

/etc/init.d/vsphere-client restart

If everything was successful, then you should be able to login to the vSphere Web Client and when you click on the main vCenter home on the left, you should no longer see the inventory tree view, just the inventory lists.

Even though we removed the inventory tree from the object navigator, you can still access the four tree views using the shortcuts found on the home page:

If you really want to disable those as well, you can comment out the following four sections:
OR better yet, re-link them to the main vCenter home view by adjusting the targetViewUid to point to vsphere.core.viHome.domainView
