Troubleshooting server-based I/O fencing
All CP server operations and messages are logged in the /var/VRTScps/log
directory in a detailed and easy to read format. The entries are sorted by date and

The following files contain logs and text files that may be useful in understanding
and troubleshooting a CP server:
■ /var/VRTScps/log/cpserver_[ABC].log
■ /var/VRTSat/vrtsat_broker.txt (Security related)
