You can enable debug logs for the VCS engine, VCS agents, and HA commands in two ways:

• To enable debug logs at run-time, use the halog -addtags command.

• To enable debug logs at startup, use the VCS_DEBUG_LOG_TAGS environment variable. You must set the VCS_DEBUG_LOG_TAGS before you start HAD or before you run HA commands.

  See VCS environment variables.

  Examples:

  # export VCS_DEBUG_LOG_TAGS="DBG_TRACE DBG_POLICY"
  # hastart
  
  # export VCS_DEBUG_LOG_TAGS="DBG_AGINFO DBG_AGDEBUG DBG_AGTRACE"
  # hastart
  
  # export VCS_DEBUG_LOG_TAGS="DBG_IPM"
  # hagrp -list
