HTC resource probe operation fails and reports an UNKNOWN state

Last published : Oct 01, 2026
This issue occurs after successfully installing the HTC agent and creating a HTC resource. If you try to probe the HTC resource, the probe operation fails and the state is reported as UNKNOWN. This is because the existing HTC.dll in the VCS bin needs to be replaced with the updated Default50Agent.dll
Workaround: To resolve this issue, you need to replace the HTC.dll with Default50Agent.dll
Perform the following steps using the CLI:
  1. Stop the HTC agent using the following CLI command:
haagent -stop HTC -sys <systemname>
  1. Delete the existing HTC.dll from %vcs_home%\bin\HTC
  2. Copy Default50Agent.dll from %vcs_home%\bin to %vcs_home%\bin\HTC
  3. Rename Default50Agent.dll to HTC.dll in the %vcs_home%\bin\HTC folder.
  4. Start the HTC agent using the following CLI command:
haagent -start HTC -sys <systemname>
