Patch ID: Patch_7_4_1_000165_3982647

* 3982647 (Tracking ID: 3982650)

SYMPTOM:
After an upgrade of InfoScale from 7.4 to 7.4.1 on Windows Server 2016, the existing Windows VSS (COW) snapshots stop working.

DESCRIPTION:
After an upgrade to InfoScale 7.4.1 on Windows Server 2016, the following error appears when you attempt to view the Shadow Copies tab on a volume: "No volume is eligible for shadow copies." This issue occurs because the existing Windows VSS (COW) snapshots fail to work.

RESOLUTION:
This hotfix updates an InfoScale 7.4.1 registry key on Windows Server 2016 and 2019 systems to address the issue. Restart the system when prompted by the hotfix EXE file.



INSTALLING THE PATCH
--------------------
This package contains self-extracting files that are specific to the processor architecture and operating system version.
Download the appropriate hotfix executable to a temporary location on your system.
You can install this hotfix using the GUI or the CLI. Instructions for both these options are provided below.


To install the hotfix on server systems using the GUI
-------------------------------------------------------------------------
1. Double-click the hotfix executable file to extract its contents to a default location on the cluster node.
By default, the files are extracted to:
"%programfiles(x86)%\Common Files\Veritas Shared\WxRTPrivates"

The Hotfix Installer Wizard is automatically launched after the files are extracted.

2. Click "Next" on the Welcome screen. 
The 'Hotfix Installation Task' screen lists the tasks that are performed by the installer.

3. Click "Install Hotfix" to begin the hotfix installation. 
The status of each installation task is updated as it completes.

4. After the tasks are complete, click "Next" and then click "Finish" to complete the installation process.

5. If this is a clustered configuration (VCS or MSCS), perform steps 1-4 on all the other nodes in the cluster.


To install the hotfix on server systems using the CLI
------------------------------------------------------------------------
1. Navigate to the following location at the command prompt:
"C:\temp"

2. Run one of the following commands to extract the hotfix files to the default location:
<Hotfix_BuildVersion_IncidentNumber_OS_Platform> .exe /x
or
<Hotfix_BuildVersion_IncidentNumber_OS_Platform> .exe /extract

3. Navigate to the default location where the hotfix files are extracted.
By default, the files are extracted to:
"%programfiles(x86)%\Common Files\Veritas Shared\WxRTPrivates\<Hotfix_BuildVersion_IncidentNumber> "

4. Run the following command to install the hotfix:
VxHF.exe /install:<Hotfix_BuildVersion_IncidentNumber>  /silent
Here, <Hotfix_BuildVersion_IncidentNumber> is the name of the hotfix file excluding the OS, platform, and .exe extension.

5. To complete the hotfix installation, follow the instructions that are displayed at the command prompt.

6. If this is a clustered configuration (VCS or MSCS), perform steps 1-5 on all the other nodes in the cluster.


NOTE: If your InfoScale cluster is not configured before the patch installation, the post-install task fails while updating the type definition for the new agents. If you encounter this situation, perform this task manually after you configure the cluster:
- To add the type definition for the InfoScale agents for Alibaba Cloud, run the batch file:
%commonprogramfiles(x86)%\Veritas Shared\WxRTPrivates\Patch_7_4_10001_3972341\InstallAgentType.bat


REMOVING THE PATCH
------------------
Additional Notes
------------------------
- To confirm the installation of a hotfix, run the following command:
vxhf.exe /list

On server systems, vxhf.exe is located at:
"%programfiles(x86)%\Common Files\Veritas Shared\WxRTPrivates\<Hotfix_BuildVersion_IncidentNumber> "

The output of this command lists the hotfixes installed on a system.

- The hotfix installer (vxhf.exe) creates and stores logs at:
"%allusersprofile%\Application Data\Veritas\VxHF"
