If your ESX host has lost connection to the vCenter server, but you can still directly access the host's management, and can find nothing else wrong with the vCenter server or its network connection to the host, you may want to the free space on your ESX host.

Logs and other temporary files may have filled up one or more ramdisk partitions (e.g. when you don't have a persistent scratch partition, it gets mounted on /tmp). This can cause any of the following issues:

Connection loss between the ESX host and vCenter server;

Errors when attempting to reconnect or add an ESX host to a vCenter server;

Errors while attempting to activate or configure HA;

Other unexplainable errors...

When you enable the ESXi Shell or SSH on a particular host in a vSphere cluster, a warning will appear on a ESX host:

ESXi Shell for the host has been enabled

or SSH for the host has been enabled

This is normal behaviour, but you can turn off these warnings for each of the hosts.

Note that prior to vSphere 4.1 Update 2, it is not possible to suppress the warnings.

Open vSphere Client.

Select the ESX host. From the Configuration tab (right pane), click Advanced Settings.

Navigate to UserVars → UserVars.SuppressShellWarning.Set its value to 1.

Click OK to confirm. The warning will disappear immediately.

Log on to vSphere Web Client.

Select vCenter from the Home menu. Select Host  ...

The vSphere Web Client may display the following error:

Failed to verify the SSL certificate for one or more vCenter Server Systems: https://vCenter-Server-FQDN:443/sdk

or

Could not connect to one or more vCenter Server Systems:https://vCenterFQDN:443/sdk

Additionally, objects such as hosts or VMs are not displayed in the vSphere Web Client.

These errors usually occur with a re-installation or upgrade of vCenter Server, where the vCenter Server is registered to the same vSphere SSO more than once.

The faulty registration needs to be resolved by unregistered all duplicate vCenter Server instances from vSphere SSO, so only the correct registrations remain.

You will have to unregister al  ...

You may have noticed that running the VMWare vSphere client on a display with higher DPI settings causes problems with the mouse cursor alignment when working inside a VM. This is because of a mismatch between the DPI settings of the VM and the DPI settings of your computer.

To resolve, right-click the shortcut to the client, go to the Compatibility tab, and enable Disable display scaling on high DPI settings.

The downside of this method is that there will be misalignment of some parts in the client, but it is still workable and moreover, it solves the mouse issue in a VM.

When attempting to add an ESX host to vCenter, you may get one of the following errors:

Error #1
Cannot install the vCenter agent service: Cannot upload agent.

Or:

Error #2
Cannot install the vCenter agent service: unknown installer error

Below is a list of most common errors:

Check whether the host is accessible through port 902/tcp. Check the firewall settings and/or routing between the ESX hosts and the vCenter server.

Check whether there is sufficient space on the ESX disk. If there's not enough space, this often gets logged in /var/log/syslog.log during the installation of a VIB.
Usually the problem occurs with the tmp partition (i.e. scratch disk) being full or almost full. You n  ...

When attempting to install or upgrade VMWare vServer server or its components, you may get the following prompt:

Please insert the Disk: 1

If you click OK, the message reappears. Clicking Cancel results in the installation to roll back.

Resolution

Copy the entire installation files to a location on the local hard drive and run the install/upgrade from there.

When running the installation from the local hard drive, and you get the error Provided password is wrong or empty, reboot and re-run the install from the local hard drive.
