Configure Snapshot and Direct I/O

To configure the Snapshot and Direct I/O features, follow these steps:

1. Enable the environment variable CAAGPERF_ENABLE by adding the following line in the agent.cfg file:

   ENV CAAGPERF_ENABLE=1
   

   Note: The agent.cfg file is in the /opt/Arcserve/ABcmagt directory.

   After you enable this environment variable, the client agent section of the agent.cfg file looks like this:

   [0]
   NAME		ABagentux
   VERSION		nn.nn.nn
   HOME		/opt/Arcserve/uagent
   ENV			LD_LIBRARY_PATH=/usr/local/Calib:/opt/Arcserve/ABcmagt
   ENV			CAAGPERF_ENABLE=1
   

2. Prepare the configuration file named caagperf.cfg in the /opt/Arcserve/ABcmagt directory. You need to specify the types of operations to be completed on the specified file systems in the caagperf.cfg file.
