For issues specifically related to SAN drives.
Server or share permissions prevent the monitoring agent from accessing a remove drive.
There are two requirements necessary to read remote share locations
To test the connection from the FglAM and agent to the remote folder:
Log in to the FglAM machine with the same user that is running the FglAM process
Open a command prompt
Run a DIR command to the share location => dir \\SERVERNAME\SHARED_FOLDER\
If any error message are encountered, add the username that is running the FglAM process to the shared location permissions.
