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"

3. Restart the 'hostd management agent' and for more information, see Restarting the Management agents on an ESX or ESXi Server (1003490).

The system cannot find the specified path - EMC Grabs error

We are trying to run the EMCRPTS___.exe (x64 / x32 bit) version on one of the server, however it is throwing some error like 'The system cannot find the specified path' and come out without prodcuing a report.

Then we tried investigating why it is not running and not creating the report in c:\windows\EMCReports folder. Found that issue with the existing EMCReports folder which is causing the issue.

When we run the EMCRPTS__.exe file, it tries to create a folder called EMCReports in c:\windows path. Some times, this folder already exists and won't allow to overwrite information under this. Remove the EMCReports folder from the c:\windows directory and re-run the EMCRPTS.exe file.
