cvgather is a tool that can be used to “gather” up all the relevant information (cfg files, etc) on your Xsan and back them up to a specified location. Any time you will be fussing around with the SAN, etc. then you should run this first. Additionally the copy of the config files can provide you with an escape clause with regard to certain issues that could cause the volume to get destroyed so I would have a copy of all your info on a location other than the SAN at all times anyway. This isn’t to say that cvgather will actually back the SAN itself up. It very specifically does not back up your data.
