Storage Foundation for Windows (SFW) and Storage Foundation for Windows High Availability (SFW-HA) store Hotfix (HF) and Cumulative Patch (CP) information in the registry.
Location (x64): HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Veritas\VPI\{ProductGUID}\WxRTPrivates\CumulativePatches
Location (x86): HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\VPI\{ProductGUID}\WxRTPrivates\CumulativePatches
Note: This registry location is also captured in the Registry.txt file captured by VxExplorer
Below this key, any Cumulative Patches or Hotfixes installed will be listed.
Example of CP7 installed for SFW 6.01:

Cumulative Patch keys (i.e. CP7_SFWHA_601) also lists all hotfixes that are installed for this particular CP. That is stored under the HFInstalledByCP registry value.

If any Private Hotfixes are installed that are not part of a Cumulative Patch, there will be an individual registry key for that hotfix listed under CumulativePatches. If a Hotfix or CP is installed, but does not appear under this key, then it most likely failed during the install. The following location includes the installation logs for the Hotfix and CP installs:
%ProgramData%\Veritas\VxHF
- vxhf.txt includes the overall installation log of all hotfixes/CPs. This will capture the CP install process which essentially is a list of multiple hotfixes that are installed individually as part of the patching process.
- Hotfix_<version>.log files is an individual log for each hotfix that can be used to review when a specific hotfix fails to install.
