VM Server going to hung state due to snapshot backup failed

Guest OS VM sessions going into hung state or unresponsive state while taking snapshot backups. The reason being, while taking snapshot backups, if any more activities planned like running some batch scripts that might cause CPU spike.

This leads to more load on the VM session, the assigned resources are not available or in some cases, the data store got filled out fast.

In this scenario, we will have stop the VM snapshot backup and reboot the server and check the logs what is the reason the server went into hung state.

If the same issue getting repeated, VMware admins can do is, when you found the VM session in unresponsive state, move the VM into suspend mode and download the logs. Later can do the investigation if needed.

How to Upgrade or Uninstall DoubleTake Version 5.2 or later without being prompted for a Reboot?

Customer needs to perform upgrade or uninstall of Doubletake Availability, Move, or RecoverNow version 5.2 or later without being prompted for a reboot.

**Solution**

Version 5.2 or later of Doubletake uses mini-filter drivers and so does not require a reboot when upgrading or uninstalling.  In order to ensure that a reboot is not prompted during the upgrade or uninstall process, however, you must stop all Doubletake services and kill any Doubletake processes running under any user on the server.

If any consoles are open or if the Doubletake.exe process is still running, a reboot may be required or a false positive message stating a reboot is required may appear. 

Once all Doubletake services and executables are stopped, there will be no reboot required for Doubletake.

Note:

Doubletake does require certain C++ components and .NET 3.5.1 components for version 5.2 and later.  If these are not present then an upgrade my require them to be installed and those 3rd party installations may require a reboot outside the Doubletake upgrade process. 

This is rare as all C++ and .NET 3.5.1 compoenents should already exist on the server already running version 5.2 or later of Doubletake.

[Solved] Browsing datastores from VirtualCenter fails: Failed to log into NFC server

Why this error occurs and the symptoms:

Downloading a file to local machine with the vCenter clients datastore browser fails with the error: Failed to log into NFC server

Connecting vCenter client directly to ESX hosts works without error.

ESX host /etc/vmware/config files contain the lines:

authd.soapServer = "TRUE"
prefvmx.consolidateDeleteNFSLocks = "TRUE"authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc"
authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl"

Solution for this issue or error:

This issue occurs when a carriage return is missing from /etc/vmware/config. To resolve this issue, go to edit /etc/vmware/config:

1. Make a backup of this file from the path - /etc/vmware/config, by executing the below command:

cp /etc/vmware/config /var/tmp/

2. Edit /etc/vmware/config so that there is a carriage return after the line:

prefvmx.consolidateDeleteNFSLocks = "TRUE"

so that it reads the below:

authd.soapServer = "TRUE"
prefvmx.consolidateDeleteNFSLocks = "TRUE"
authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc"
authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl"
